Decanter centrifuges are Specially Designed for the Drilling Mud Solids Control

Decanter centrifuge is the last stage equipment in drilling mud system for solids control and mud cleaning. The superiority of decanting centrifuge is embodied in the solids processing size. Decanter centrifuge could remove the solid particles with size 2-7 microns using the principle of centrifugal action, it is an ideal choice for separating particles in drilling mud.

The decanter centrifuge separates solid materials from liquids in slurry and therefore plays an important role in wastewater treatment, chemical, oil and food processing industries. There are several factors that affect the performance of a decanter centrifuge and some design heuristics to be followed which are dependent upon given applications.

Decanter centrifuges are specially designed for the drilling mud solids control. The effective centrifuging and fine drilled solids separation can remove significant quantities of inseparable solids. This significantly reduces the tranditional dilution requirements and drilling waste management volume.For drilling fulids processing there are two uses of decanter centrifuge. One is to remove solids from the mud while returning the liquid phase to the active system, such as when used with an unweighted drilling fluid. The other is when solids are returned to the active system and the liquid phase is discarded.

Hi-g dryer is the most important equipment used in Drilling waste management ( DWM )

Zero waste discharge still remains a bit away after going through the previous four steps, therefore solidification, thermal desorption, cuttings reinjection and biodegradation will be utilized to push towards the goal as the last step. Hi-G dryer: KOSUN Hi-G Dryer can recover water- and oil-based mud in drill cuttings with fluid phase down below 10% and remarkable reduction on waste discharge cost. It is especially good at managing oil-based drill cuttings.

Drilling waste management ( DWM ) is a new industry when environment is getting more important. KOSUN Solids Control is a leading supplier with a complete drilling waste management system including Hi G dryer, vertical cuttings dryer and decanter centrifuge. The Hi-G Dryer has been proved to be extremely effective in recovering the oil-based mud cuttings. It is a kind of shale shaker mainly used for drying the drilled solids. The feeder installed on such hi-g dryer is a little different from normal shale shaker, so as to achieve the best efficiency.

Another major benefit of the Hi-G dryer technology, sometimes overlooked, is the elimination of whole mud losses from the shaker. This historically has ensured that the shakers were never run at their optimum capacity and thus the solids control system efficiency was adversely affected. Incorporating the Hi-G dryer down steam allows the shakers to be run close to maximum capacity without the concern of whole mud losses.

KOSUN DWM Solids Control can Low Emissions and Land Dump Processing Costs

Low emissions and land dump processing costs, but also Desilter is comply with prevailing regulations. Therefore, the worker or service company, the actual amount of DWM Solids Control generated and subsequently discharged of drilling mud agitator is not of concern. In fact, there is a dispute arising from a service company to reduce the number of drilling mud agitator and waste and is harmful, because the number of these wastes of Shear Pump is the main basis for compensation. In the 20th century, Shear Pump's to the early 1990s, people understand the level of awareness among environmental issues has been greatly improved.

For DWM Solids Control characteristic sound technology research carried out drilling waste. Mainly in two steps: first, the laboratory successfully synthesized polymer organic cationic flocculant - Sand PumpIS diallyl dimethyl ammonium chloride - acrylamide copolymer (PDA), and with the use of inorganic flocculants, preferably a flocculation - settlement formula DWM Solids Control; and second, the drilling waste water flocculation - resulting sludge together with the waste drilling mud treatment for curing settlement, Sand Pump developed a recipe and construction program of drilling waste solidification process.

In recent years, forced the world demand for energy, leading to increasing types of drilling fluids, Drying Shaker additives and toxic ingredients are increasing, its composition is extremely complex. However, with the world to improve environmental protection requirements, sound management of drilling waste management system has become a serious problem. This DWM control analyzes the composition of the drilling waste from the drilling fluid and the harm to the environment, technology and methods for disposal of DWM Solids Control at home and abroad in recent years, various oilfield drilling were reviewed.If you want to know more about drilling waste system management,please write to me on [email protected].

Hi-g dryer and VERTI-G Cuttings Dryer in Drilling Waste Management

As a result of a lot of barrels of DWM solids control were generated every year, principally together with drilling fluids and drill solids, particularly oil-contaminated drill cuttings. KOSUN Solids Control is the leading manufacture in China for solids control equipment, drilling waste management system is the new industy and few of China manufacturers build equipment for drilling wastement management equipment till now. Hi-G shaker is one of the equipment for drilling waste management system.

The following description will focus on the basic construction and spare parts of the Hi-G Dryer.The base of High-G Dryer is bigger than shale shaker. The difference between the shaker screen and Hi-G Dryer focuses their processing materials shale shaker processes the drilling mud and the High-G dryer deals with discharged drilling waste separated by solids control equipment. In drilling operations, typical solids control equipment discards 1-4 barrels of liquid for each barrel of solids removed. Studies have shown that the Vertical Centrifuge can recover one bbl. of fluid, for each 2.5 bbl. of solids exiting the Vertical Dryer. This recovery is measured after processing through the solid bowl-decanting centrifuge. The vertical centrifuge makes its contribution with its innovative process after the shale shaker completes its task. Cuttings that pass over the shaker typically have an average of 30% to 50% ROC (Retention on Cuttings) when they enter the proprietary auger system and begin to cycle through the VERTI-G cuttings dryer.

Hi-g dryer can also be used to recover the oil-based, water-based and synthetic-based waste in drilling cuttings. Various number of hi-g dryers can be equipped as per the conditions at drilling site. The hi-g dryer independently developed and manufactured by KOSUN features with high G-force vibration intensity (adjustable) and excellent screening and drying effect. The frame angle can be adjusted from -1° to +5° via AWD angle adjustment system in continuous operation state. The liquid ratio of drilling cuttings can be reduced to below 10% after treatment, significantly reducing drilling waste discharge costs. To develop zero contaminants discharge policy through implementing drilling waste management. The first move is to minimize as much as practical the amount of waste generated in solids control system processing. Then reduce the holes diameter (less cuttings generated & less mud to be disposed off) by optimizing the well casings program for every single well.

KOSUN Drilling Mud Solids Control Equipment Used in Drilling Engineering

In oilfields drilling plant, normal working state of any system equipment is the basic requirement of drilling. Solid control system is one of the most important circulation system in the drilling process, and in last essay, three kinds of common faults and according solutions have been described. In this essay we will mainly talk about another tips of drilling mud solids control equipment operation, which will improve drilling efficiency to a great extent.

If desilter and desander share the same suction tank, then half of the drilling mud is separated by the desilter and the other half by the desander. This is the common phenomenon in the total design and installation in solid control system. If the centrifugal pump pressure is 30 meters and the hopper nozzle flowing capacity is 25L/S, the 30 meters pressure head and the hopper nozzle speed is still the same as before.KOSUN sand pump is manufactured with tungsten carbide mechanical seal and the impeller can lower axial thrust loads and make it easier for installation, repairing and maintenance.This purchase contract refers to dozens sets of equipment, includind shale shakers, vacuum degassers, mud cleaners, decanter centrifuge, screw pumps, centrifugal pumps and more than 1000 pieces of shaker screens.

In conclusion, drilling mud is the blood of the whole drilling mud solids control engineering. If the solid particles contained in the drilling mud are too large and excessive, well blowout or jamming of a drilling tool may be caused, which is unfavorable to control of drilling speed and costs. KOSUN promised to send experienced engineers to the oilfield drilling site for excellent technical service and would provide more competitive price for future purchase, which will bring more benefit to both parties in this win-win relationship.

High G-force vibration of KOSUN Hi-G Dryer

Dryer shaker is popular used for water based mud drilling cuttings treatment. After Hi-G dryer, high speed solids control-centrifuge will be followed for further treating. After treated by decanting centrifuge, solids parts can be used for construction; liquid part can be further treatment by flocculent unit. Hi-G dryer is also can be used for oil based mud drilling waste treatment; vice versa, vertical cuttings dryer can also be used for water based mud drilling cuttings management. Based on this, KOSUN design it’s vertical centrifuge which can be used for both WBM and OBM drilling waste treatment.

The generation of fine solids are by far the largest concern within the industry. KOSUN HI-G Dryer provides the most cost effective solution to handling these fines. This proven technology consists of a High G-force vibration intensity (adjustable as per working conditions),Weir type feed box is more applicable to on-site process;Fast drilling cuttings conveying speed and high handling capacity;Screen frame tilt angle can be adjusted from -1° to 5°;Rapid screen tensioning system ensures easy screen replacement.

KOSUN Hi-G Dryer is used to recover the mud from drilling cuttings, so as to reduce the liquid/oil content in drilling cuttings to as low as about 10%(w/w) and recover part of the drilling mud, so that the drilling cost can be reduced and the drilling waste volume can be cut down, for the purpose of reducing environmental pollution.

During the traditional drilling process, waste pit is built at the drilling site for drilling waste management. That is, drilling waste management system is discharged to the waste pit at ground level for next-stage treatment, or even directly buried. This traditional discharge mode causes serious pollution and great harm to the environment and human life; therefore, State Environmental Protection Administration of China made a formal legislation in January 2015 to put forward stricter requirements and standards for drilling waste management.

Six Steps to Install Drilling Fluids Decanter Centrifuge

Decanter centrifuge is really one of the most useful machines, because it has found wide application in many industries. The commonest industries include oil well drilling, biological wastewater treatment, food processing, chemical slurry and other fields. It is used to extract particles from liquids.

KOSUN Drilling Mud Decanter Centrifuge efficiently removes undesirable solids from drilling mud in crude oil extraction. The decanting centrifuges are designed specifically to remove unwanted solids and fine particles from virtually all kinds of used drilling mud, including those based on water/synthetics and conventional oil-based drilling fluids.

Six Steps to Install Drilling Fluids Decanter Centrifuge:

1. Drilling solids decanter centrifuge ought to sit far from the inlet of mud pump for a full agitation in the mud.

2. Firm installation of drilling solids decanter centrifuge is important, so its 4 legs ought to be fixed on the surface of tanks with bearing bars.

3. Its installation also involves protruding the discharge groove from the tanks and connecting it with hydraulic supply line for a better performance of sand discharge.

4. Mud pump ought to stand behind desander and desilter, and connect tightly with feed pipes and inlet pipes.

5. Join together the flushing feed pipes and perforated pipes on inlet pipes and the tank.

6. Plug in and switch on all the parts of drilling solids decanter centrifuges for the sake of repairing safety.

Much current centrifuge application with drilling fluids is not only unproductive, but is counterproductive. One example of misuse is the practice of running two centrifuges in parallel to "recover the barite" with the first and "discard the drilled solids" with the second. The first stage is traditional centrifuging, returning the underflow to the active mud system. Rather than discarding the overflow, it is routed to the second centrifuge running at a higher speed, where the low-gravity solids supposedly are discarded and the "clean" liquid is returned to the mud.

Solids Control System can Effectively Treat the Harmful Solids

As well known everywhere that complete solids control equipment is an important demonstration of scientific drilling. The continuous enhancement within almost a decade remarkably brings about better drilling techniques, less maintenance on circulating system, faster drilling velocity and lower costs.

The key point for achieving drilling fluid recycling is to effectively treat the harmful solids contained within. Solids control system can effectively achieve such a goal. In the system, shale shaker can remove harmful solids with diameter ≥74μm, desander can remove those with diameter of 44~74μm, desilter can remove those with diameter of 15~44μm (high efficiency cleaner is a kind of equipment integrating both desander and desilter and can remove harmful solids of 15~74μm) and centrifuge can remove those with diameter ≥2μm. Mud density may not be too high during normal operation to reach its performance requirements, so the density must be reduced to a proper value, and solids with diameter less than 15μm need to be treated by centrifuge. If barite is required to be recycled while treating harmful solids, a high speed centrifuge is necessary.

Thus it can be seen that drilling fluid can be recycled through the above sequential treatment by solids control system, which greatly saves drilling cost and enhances drilling profit. Xi’an KOSUN Machinery, Co., Ltd. has been dedicated to research and design of solids control system and equipment since 1992. KOSUN has possessed fairly mature technical system through over 20 years of experience and is capable of designing reasonable and effective solids control system solutions according to customers’ requirements.

How to reasonably layout solid control equipment in mud cleaning system?

Drilling mud solids control process request main equipment including shale shaker, desander, desilter, decanter centrifuge. All other equipments in drilling fluid system are assistant ones. The mud equipments improvement should be based on certain well drilling condition and mud conditions. Such as decanting centrifuge process. Sometimes, we need high speed centrifuge to process finer particles but sometimes we need middle speed ones to process larger quantity drilling mud with larger cuttings.

How to reasonably layout solid control equipment in mud cleaning system is very important. If the performance solid control equipment is good but layout is not very good, the function is only a half even have not functions. If the layout or performance is unreasonable, the content of solid phase in drilling fluid will increase. So we must dilute and use large chemical agent to process it and increase the cost of drilling fluid maybe led to well mouth appears complex accidents.

As everybody knows, solids control equipment is one of the most important systems in the petroleum drilling engineering. For the last few years, the solids control equipment taken place a great changes, and the changes speeded up the drilling industry development process. KOSUN as the pioneer in this industry they organized technology team to development and improved all the solids control system equipment and drilling waste management equipment which can better used in domestic and foreign industry experts.

Now, solids control equipment in the oil drilling solids control application include: shale shaker, desander, desilter, mud cleaner,shale shaker screen,horizontal spiral centrifuge, vacuum degasser,liquid-gas separator,drilling waste in drilling companies, mud stirred , a jet mixing devices, electronic ignition devices, drilling waste in drilling companies,mud gun, desilter,mud agitators,screw conveyor, sand pump, cut pumps. While being widely used in sorting ore, coal washing, dewatering and starch separation industry.

The essential style consists of enormous, flat sheets of wire mesh screens or sieves of varied mesh sizes that shakes or vibrates the drill cuttings. Commonly, in shale shaker, the drilling fluids flows across and off the shaker screens and back to the drilling fluids process system that is commonly known as a mud system. This separates the drill cuttings, usually known as solids, from the drilling fluids in order that it will be recirculated backtrack the well bore. In field business, linear motion shale shaker is wide used for lubricating substance solids management of oil &gas well drilling for rig.

Vertical Cuttings Dryer System can treatment the OOC is lower than 5%

As is well-known, vertical cuttings dryer is the mostly used important equipment for drilling waste management. It is also called VERTI-G cuttings dryer. KOSUN vertical cuttings dryer has been proved with excellent performances during drilling waste disposal process. The vertical cuttings dryer is a machine designed to reduce the operator’s total fluids cost and limit waste disposal volumes.

The VERTI-G dryer system catches any lost mud and returns it to the active mud system. The recovery systems work well with diesel, mineral and synthetic oil based mud. The system has proven to be more efficient with synthetic systems due to the ease of oil separation from larger cuttings. Synthetic systems also have a higher mud value, which makes the machine more attractive from an economical point of view. In addition, the system reduces the amount of wastes at the rig site and the resulting disposal costs.

Cuttings dryer can effectively treat the water-based, oil-based, and synthetic-based drilling mud, generate very dry drilling cuttings, reduce the discharge volume of drilling cuttings and recover precious drilling mud, so as to improve comprehensive drilling cost-effectiveness. The vertical centrifuge independently developed and manufactured by KOSUN features with mature performance, including super strong separation ability. With top feeding mode and built-in high speed centrifugal drum, it can achieve the maximum handling capacity of 60T/h, and the OOC of drilling cuttings after treatment is lower than 5%.

Since the waste to be disposed contains much water and consumes lots of chemical agents, the solution costs much, achieves unsatisfactory results and fails to completely eliminate pollution risks. Facing local governmental requirements on environmental protection, domestic onshore oilfields now attach more and more importance to harmless drilling waste treatment and as a result, the disposal technology with solid-liquid separation as its core is applied to the drilling waste management, which replaces the out-dated direct solidification with the process integrating chemical method, solid-liquid separation and solidification method.

KOSUN VC-1000 series Vertical Centrifuge can meet the Drilling Waste Treatment

As well know,vertical cutting dryer is also called vertical centrifuge, it is a very important part for drilling waste management on treating oil-based mud.KOSUN Vertical Centrifuge has been done strict balance testing for all major rotary components to minimize vibration and noise. The Vertical Centrifuge is the ideal products for oil-based drilling waste management.

KOSUN VC-1000 series Vertical Centrifuge produced by KOSUN is a type of vertical centrifuge, which can perform solid/liquid separation through centrifugal separation. The vertical cuttings dryer can effectively recover the liquid phase in drilling cuttings, making the solid phase become very dry. It is suitable for water-base mud, oil-base mud and synthetic base mud. By recovering the mud in drilling cuttings, the vertical cuttings dryer can reduce the drilling cost and cut down environmental pollution. With handling capacity of 40-60 T/h, the oil on cuttings (OOC) of drilling cuttings can be reduced to lower than 5% (w/w) after treatment, meeting the international emissions standards and environmental protection requirements. The vertical centrifuge can also be applicable for drilling waste management in onshore and offshore drilling.

VERTI-G Cuttings Dryers uses centrifugal force to dry drilled solids in oil or synthetic base fluids. A stainless steel screen bowl traps “wet” solids and accelerates them up to 900RPM with G force up to 420. Liquid is forced through the screen bowl openings, while “dry” solids are extracted by the angled flights attached to the cone, which rotate slightly slower than the bowl. Tungsten carbide protects the flights from abrasive solids and ensures long operational life. This aids in maintaining a constant gap between the scroll and screen bowl, which is crucial for vertical cutting dryer proper operation.

With the growing market for drilling waste management, now KOSUN has developed the vertical centrifuge. In China, KOSUN is the only API-certified company who can provide cutting dryer. As one of the first company who develop the drilling waste management products, KOSUN has already developed the vertical cuttings dryer in 2011 which is much earlier than our competitors. More important, KOSUN has a lot of successful cases for the waste management products around the world.

#Vertical Centrifuge

VERTI-G Cuttings Dryers System is the Ideal Drilling Wast System Equipment

KOSUN vertical cuttings dryer is that the ideal product for oil based mostly drilling waste management. A chrome steel screen bowl traps “wet” solids and accelerates them up to 820 rev with G force up to 360. Liquid is forced through the screen bowl openings, whereas “dry” solids ar extracted by the angular flights connected to the cone, that rotates slightly less slowly than the bowl.

The vertical cuttings dryer could be a machine designed to scale back the operator’s total fluids price and limit waste disposal volumes. This is often achieved by directly sick the fluids from the cuttings, and by sick any weighted mud from the shaker screens avoiding that it is lost thanks to a failure of the shaker, a movement of the rig or the occlusion of the screen. The machine helps meet sure fluid-on-cuttings discharge necessities that has to be abided by.

Vertical Centrifuge (VC) could be a continuous screen sort centrifuge with automatic feed management designed for liquid-solid separation. The VERTI-G cuttings dryer is meant to recover the liquid section of the lubricator from trained solids by exposing the latter to terribly high centrifugal acceleration forces that improve fluid separation from the drill cuttings.

By additional informative the expensive liquid section which may be came to the active lubricant system, the machine helps save cash on the expensive drilling fluids. Usually shaker screens get clogged and, as a result, expensive mud is lost overboard. The VERTI-G Cuttings Dryers system catches any lost mud and returns it to the active mud system. The recovery systems work well with diesel, mineral and artificial oil based mostly mud.
