INTRODUCTION 4: GN Desilter’s Application in Treating the Drilling Fluid

Desilter, which is another kind of solids control equipment for treating the drilling fluid. In this article, we will mainly introduce the Desilter made by GN Solids Control. 

Actually compared with the desander, the desilter has the same working principle, similar structure and different configurations for customer option.

Usually desilter is matched together with the shale shaker and desander and used for doing the 3rd-stage separation with the drilling fluid. 

Most of the big sizes of drilling cuttings over 40μm will be separated after being treated by the shale shaker and desander. In next step the drilling fluid goes into the desilter and most of the solid particles over 20μm are separated out from the fluid and the drilling fluid become much more clear. 

The main part of desilter is also the hydrocyclones, but the size is different with the desander’s. Each hydrocyclone used on GN’s Desilter are 4 inches and its standard treatment capacity is 20m³/h. Usually 8 units, 12 units or 16 units of hydrocyclone are standard configuration on GN’s Desilter, the corresponding standard treatment capacity is 120m³/h, 240m³/h and 360m³/h. It is also customized and the customer could choose specific quantity of hydrocyclone for different treatment capacity. 

In most of the time the desilter is recommend by GN Solids Control to be combined together with 1 shale shaker (the desilter & shale shaker AIO), as the separated solids particles could be further dried by through the shale shaker’s screen and the drying effect could be better, especially for the weighted drilling mud.

Sometimes, the customer needs the desilter, shale shaker and desander to be combined together and turned into an all in one machine because of being limited to the space, Now GN has the “Mud Cleaner” for customer option.

INTRODUCTION 3.1: GN Desander’s Application in Treating the Drilling Fluid

In this article, we will mainly talk about the desander’s working principle. 

Desander, one of the most widely used solids control equipments used on treating the drilling fluid. 

As we know, with the drilling fluid circulates the drilling cuttings chipped away by the drilling bit continuously when the drilling rig is working, the different sizes of drilling cutting goes into the drilling fluid and the physical properties of drilling fluids will be changed, such as the density, viscosity, solid content, etc. The drilling fluid could not meet the further work demand. 

In order to save the cost and protect the environment, in most of the time the drilling fluid needs to be recycled. Now the Desander and some other necessary solids control equipments like Shale Shaker, Desilter, Decancter Centrifuge will be worked together for treating and cleaning the drilling fluid. By through treating the drilling fluid, the different sizes of drilling cuttings will be separated out and the physical properties of drilling fluid will be recovered.

According to the technical design, the Desanders made by GN Solids Control company are usually used for separating out the solids particles over 40μm in the fluid loop. 

Normally the desander is used for doing the 2nd-stage treatment with the drilling fluid that after the 1st-stage treatment by Shale Shaker. The main part of 1 desander is the Hydrocyclone. Its work principle is as below,

1.      Normally pumping the treated drilling fluid by Shale Shaker to the Desander and the fluid goes into the Hydrocyclones of desander; 

2.      Operated by the centrifugal force and as the centrifugal forces are different for the solid particles and liquid. 

3.      Finally, the solid particles will be drained out together with some liquid from the underflow port together; the clean drilling fluid will be drained out from the overflow port.

1. GN Shale Shaker & Desilter AIO (all in one machine)

Compared with separate shale shaker or desilter, this AIO machine’s function could be much stronger and the whole structure could be more compact. It has 2 stages function for treating the drilling fluid. 

The 1st stage is by using the shale shaker for separating out the solid articles over 100μm usually; The 2nd stage is by using the desilter for separating out the solid articles over 20μm usually; 

The quantity of the hydrocyclones of desilter is selectable based on different treatment capacity in unit time.

2. GN Shale Shaker & Desander AIO (all in one machine) 

This machine is the combination of shaker and desander. Compact structure and perfect work performance make it popular in all most all the drilling industries. 

The desander is usually for separating out the solid particles over 40μm in the drilling fluid. Firstly the drilling fluid is screened by shale shaker and then treated by desander. Based on the requirements for different treatment capacity in unit time, the quantity of hydrocyclones of desander could be selectable.

3. GN Shale Shaker & Desilter & Desander AIO (all in one machine) 

Actually this combination of shaker, desilter and desander is called “Mud Cleaner” in GN. Its advantage is also compact structure and has the complete functions for treating the drilling fluids with 3 stages. 

The 1st stage is by shaker, usually the solids particles over 100μm in fluid could be separated out;

The 2nd stage is by desander, usually the solids particles over 40μm in fluid could be separated out;

The 3rd stage is by desilter, usually the solids particles over 20μm in fluid could be separated out; 

This machine has 2-layer screens. The lower screen is used for doing the 1st stage separation, the upper screen is used for further screening the separated solid particles by desander and desilter and reducing the water in the solid particles.

INTRODUCTION 1.2: GN Shale Shaker’s Application in Treating the Drilling Fluid

In this article, we will mainly talk about GN shale shakers with different treatment capacities, different types of Shaker Screen for customer option. 

1. GN Shale Shaker with different Treatment Capacities.

As decided by different drilling rigs and well depths, the needed drilling fluid volumes are also different. GN’s Shale Shakers have different drilling fluid treatment capacities for customer option. 

2. GN Shale Shaker with different types of Shaker Screen.

As the necessary part of 1 complete shale shaker, GN has many different types of shaker screen with high quality and competitive price for customer option. Besides, the shaker screens that GN manufactures could not only be used on GN’s shaker, but also could substitute most of the screens made by other solids control companies on the global market.

If customer has the requirements for substituting the other company’s shaker screen by using GN’s, it is just needed to provide the specific dimensions, the mesh number, the original shape, and the free samples could be sent for trying. The details are as below,

2.1.GN Steel Frame Screen

The steel frame screens are most applied to the shale shaker. The screen frame adopts high-strength square steel tube welded to multi-ribbed construction. They are sturdy and reliable. The screens are constructed with 2 or 3 stainless steel layers bonded to a steel support plank. 

2.2. GN Pyramid Screen

This type of screen is the replacement product of flat screen. The effective area is 125% to 150% of flat screens. Without changing the construction of shakers, the using of the screens can improve the quality of drilling fluid and increases the production. Screen has typical mesh cloth that appears regular waves. And it can be mounted on suitable shaker by hookstrip or wedge-shape fastening device. As compared to flat screens, this screen has higher treatment capacity by reason of more useful area. 

2.3.GN Composite Screen

INTRODUCTION 1.1: GN Shale Shaker’s Application in Treating the Drilling Fluid

With the development of drilling technology, and the idea promotion of environmental protection and cost saving, GN Shale Shaker has been more and more widely used in drilling industry for cleaning the drilling fluid. GN Shale Shaker widely services the global customers like from Oil & Gas Industry, HDD & CBM industry, with the customers of HALLIBURTON, BAKE HUGES, SCOMI TOOLS and so on. 

Drilling fluid, known as the mud, has several different functions to drill an oil or gas well, including subsurface pressure control and cuttings removal, which also reduces the friction between drill bit and the wellbore. 

When the Drilling rig is working, the drilling cuttings that chipped away by the bit goes into the drilling fluid and its technical parameters like density, viscosity and special gravity will be changed and could not meet the drilling’s requirements, seriously the Well Kick or Well Blowout could be happened. 

The drilling fluid circulated the cuttings to the surface, as the sizes of cuttings in the drilling fluid are different, in order to promote the treatment efficiency and effect, usually the cuttings needs to be separated out by adopting multiple-stage separation. The Shale Shaker is matched together with the Desander, Desilter and sometimes the Decanter centrifuge is also equipped, to treat the drilling fluid and recover its physical properties. 

Normally the Shale Shaker is used as the 1st-stage drilling fluid purification equipment. It is mainly used for screening out the big size cuttings like over 100μm. The working principle is as below, 

1.      The fluid pump circulates the fluid from the fluid pit to the Shale Shaker;

2.      There are vibration motors installed on the Shale Shaker. The motors produce shaking force and the fluid moves on the Shaker Screen.

3.      The big size cuttings could not go through the Shaker Screen and are discharged. The treated drilling fluid will go to the next-stage for continuous cleaning. 

Based on the different requirements of customers from different industry, GN could provide the standard shale shakers and customized ones for customer option. Such as different treatment capacities, different types of shaker screen, different combinations of Shale Shaker with Desander or Desilter, Desander and Desilter together.
