Although the major share of GN products are used for oil and gas industry, GN Solids Control also occupies the first place in market share in HDD, CBM ,TBM and Loop Zero Discharge System. And among all GN HDD mud recycling systems, the 500 GPM capacity is the most popular among the users.
Picture below is one set of GNMS 500GL HDD System for a jobsite inside China, this is the 3rd project this system is used to serve and GN Solids Control sent engineer to jobsite help to re-set up of the system.

GNMS series mud recycling system is high standard configuration of GN mud recycling systems, they are perfect solution for HDD projects because:
1. GNZS703E-DZ shale shaker is a mature design of GN Solids Control, it use 3 pcs of shaker screens and the screen area is 2.63 cbm. Same as all the GN Shale Shakers, GNZS703E-DZ shale shaker uses the patented technology for the deck sealing in order to prevent leaking of liquid. Shaker deck frame is Stainless steel to have stronger structure for a longer service life. Unless its peer model GNZS703E-HB which is designed for oil and gas solids control system, this model of shale shaker is suitable for get fed via a submersible slurry pump from a mud pit. It is designed especially for the HDD projects.
2. GNZS-703E 1S8N mud cleaner is a combination of the 2nd and 3rd separation steps with desander cone and desilter cones, and the shaker below is used as a under shaker for both desander and desilter cones. GN choose polyurethane cyclones as the desander and desilter cones, more wear proof and longer service life than the metal material ones.
3. As high configuration of GN mud recycling systems, GNMS 500 GL has mixing hopper and mixing pumps for adding new chemicals into the well cleaned drilling mud after recycled. And this 500 GPM system has a larger storage capacity comparing with the standard GNMS 500G system.

1. To make sure the operation of the shale shaker and normal usage life on screen, the operator need to make sure parts like wedges, screw cap bolt and springs on the shale shaker are installed correctly with no signs of wrongdoing. The operator installs the screens according the operation manual provide it from the seller.
2. To get full usage of the pre-tension shale shaker screen, operator need to ensure the rubber parts of the shale shaker is fully intact and show no sign of damage. Shale shaker screen is wear and tear parts and it will be needed for replacement after normal usage. If wear-down speed is faster than normal, then check all the moving parts of shale shaker is functioning properly and secure the screens correctly.
703 Shale Shaker 2
3. Lubrication and consist maintenance the shale shaker moving parts base on the operation manual is the must to ensure proper operation.
4. If the operator uses an OEM shale shaker screen that have not been pre-tension treatment, it is the must step that need to perform before usage.
5. If the drilling fluid flow out of the pore or damaged place, then cuttings can’t be removed. Any screen with holes or be damaged must be changed immediately, the hole and the damaged place can be sealed up by the panel. The screen must be changed as soon as possible, make a plan before the replacement to reduce the stopping drilling time, you should prepare the tools and screen before beginning to replace, if because the shale shaker is not operating, it will increase the cuttings content. It’s best to exchange the screen in a single period if possible. Need to stop the pump at the emergent time, stop drilling so as to replace the screen of shale shaker.
6. Any problem please fell free to contact us and learn to know our other products including mud agitator, decanter centrifuge, desander, mud tank ,drilling waste managent, drilling mud system etc.

It is widely acknowledged that solids smaller than 75 to 100 are removed by desanders, desilters and mud cleaner, all of which use a device called a hydrocyclone to separate out solids. GN polyurethane material hydrocyclone is able to handle with abrasive and coarse solids for long time service

Working procedures:

Mud Cleaner

Two desander and twelve desilter cones mud cleaner

Firstly, the mud is propelled at high speed into the top of an inverted cone along a tangent. The large and heavier solids is pressed to the side of cone under the centrifugal force then subsequently slowly drift down and are finally discard to the mud pit or on the shaker screen. Secondly, the remaining fluid and smaller particles are forced to the center of the cone and ejected out of the top. The same working principle is for the desander and desilter. Technically, there are 4 inch or 5 inch cone for the desilter and 10 inch or 12 inch for the desander. In theory, a 4-inch hydrocyclone discards particles as small as 15 microns, but de silter is down to the about 20 microns in the field statistics.

Hydrocyclone has several ways to install:

1. Desander comprises one(528GPM), two(1056GPM) or three large (1584GPM) diameter hydrocyclone on the tandem.
2. Desilter comprises several of 4 inch diameter cone 8(528GPM), 12(1056GPM) and 16(1584GPM). For HDD project or small bored pile system, GN can only install 4 or 6 desilter cone for processing.
3. GN provides the relative shale shaker matching with desander and desilter from two panels linear motion shale shaker to four panels shale shaker.
4. In order to save clients operating space, GN even put forward to double deck shale shaker, Bottom deck retain the big solids as the shale shaker, top deck with hydrocyclone working as desander or desilter. Double deck desander or desilter are widely used for the HDD or small drilling system.

GN Provide a variety of desander, desilter and mud cleaner solutions for the specific mud recycle project. GN you best partner

Obviously, drilling conditions and cuttings volumes change constantly during the course of constructing a wellbore. Dual-function and small space equipment is recognized by the most project contractor. GN 705E Double deck with multi function dynamically manages fluid quality throughout the drilling process. The double deck shaker with de sander or de silter is widely applied for the HDD and well drilling field

 1.Double deck shaker with one de sander hydrocyclone cone

Fluids will firstly be pumped onto the bottom shaker, the shaker screen is small API number to separate the lar123ge particle from the fluid. Secondly, GN high effective centrifuge pump will transfer the fluid to de sander cone for second step process. The top deck will handle the fluids from apex of de sander cone.

 2   Double deck shaker with 4,6 or 8 sets of de silter cone

The working principle is the same as the de sander. But the feeding type is very simple way in which can save the working space. Higher mesh shaker screen is applied on the shaker than de sander shaker. It is effective for the 250GMP and 350GPM capacity

GN double deck shaker delivers the flexibility required to optimize fluids capacity and fluids recovery. Also, it fits well within tightly constrained workspaces. For your jot site, GN double deck shaker is very smart plan.

To clean the mud from the slurry used complex mechanical devices such as shale shaker, mud cleaner,centrifuge and cutting dryer

Mud Cleaner with Desander and Desilter

Mud Cleaner with Desander and Desilter

GN Mud Cleaning is Including Hydrocyclones and Shale Shaker

There are parallel hydrocyclone ( Desander and desilters ) in the mud cleaner.  Hydrocyclone installation is used as second and third mud cleaning equipment. Their operating principle is based on the separation of the suspended particulate under the action of inertia forces arising in a vortex flow of the hydrocyclone. For separating sludge from drilling fluid, the second stage is called desander cyclone separator for oil & gas drilling un-weighted drilling mud, and the cyclone is 10”.  Desander cyclone is focused on cleaning the mud from cuttings particle size between 70 microns and 40 microns in drilling oil and gas project.

Desilters are devices for circulating and cleaning the drilling mud processing as the same as the desander. Desilter with hydrocyclone 4 “is the third stage in the circulation system for cleaning mud at oil and gas drilling, is used to separate the solid particles with an average particle between 40 microns and 20 microns.

GN mud cleaner offer the 528GPM, 1056GPM and 1584GPM treating capacity for customer. Please contact with us if you are interested in our equipment

Typical application of solid-liquid separation is in the process of oil drilling mud solid-liquid separation. Used for separating solid particles in drilling fluid, according to the diameter size of hydrocyclone can be divided into desander. Desilter and micro cyclone three categories. 1 the desander In 150 ~ 300 mm diameter cyclone called desander. When pressure is 0.2 MPa, the capacity of a single hydrocyclone is 20 ~ 120 m3 / h separation size in 40 ~ 74 microns. In the design selection using, 125% of the rated capacity shall be the largest drilling fluid displacement. (2) the USA desander  A diameter of 100 mm and 125 mm called desilter of hydrocyclone When pressure is 0.2 MPa, the capacity of a single hydrocyclone for 10 ~ 15 m3 / h normal work, desilter can remove 95% larger than 40 microns of drilling cuttings and 50% greater than 15 microns of drilling cuttings, and at the same time to remove 12 ~ 13 mu m barite, therefore cannot be used to deal with increase in the use of design model selection of drilling fluid, the frontal go capacity shall be the biggest displacement of drilling fluid 125% ~ 150% (3) the micro cyclone Known as a diameter of 50 mm hydrocyclone

The significance associated with drilling liquids

The  USA desander  is  a  important  mud  weapons  is  mostly used in  oil  drilling  mud  management  The  machine  a fundamental element of gas and oil drilling: with regard to maintaining down-hole demands, lubricating the actual exercise chain, air conditioning the actual little bit, cleaning up the underside pit, moving the actual cuttings towards the area, stopping nicely blowouts as well as supplying geologists having a way of sample the actual development thats becoming drilled via. Within directional drilling, its dirt which becomes the actual exercise little bit. Drilling dirt wouldn’t end up being removed therefore optimizing as well as managing each one of these features demands steady tools.
