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.

Different
customers have different requirements with the desander, like different
treatment capacities, different configurations and so on, in this article we
will mainly talk about the different types of desanders made by GN Solids
Control Company for customer option. 

1. Firstly we will
talk about the different options of treatment capacity with the Desander. 

As we know, the
main part of 1 desander is the hydrocyclone. For GN’s desander, each
hyrocyclone is 10inch and the treatment capacity is 120m³/h. So the quantity of the hydrocyclone is
optional based on customer’s requirements. Such as below,

2. Sometimes, the
customer needs compact structure as limited by floor space but complete
functions, GN could also provide different corresponding configurations for
customer option, the details are as below,

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

The desander could be
combined together with different types of shale shaker.

·For the Oil & Gas Drilling with small
rig, CBM drilling, HDD, water well drilling and so on, customer could choose
the desander combined together with a mini shale shaker to get an economic
choice and acceptable drying solids;

·When customer needs the big treatment with
compact structure, like for the Oil & Gas Drilling with big rig, large HDD
rig, Tunneling Boring Machine and so on, the densander combined together with a
big shale shaker is available. 

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

As we introduce it
before, this machine is also called “Mud Cleaner”. Different types of desander,
desilter and shale shaker are combined together and many different
configurations are gotten for customer option. The details are as
below,

Besides, while the
3 equipment are combined together, but they all work independently and the
desander and desilter are demountable when customer only needs the shaker.

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.

In
this article, we will mainly talk about GN shale shakers’ different combinations
with Desander or Desilter, Desander and Desilter together are also available
for customers. The details are as below, 

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.  

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
