jet mud mixer

500GPM is the most popular capacity mud system for HDD, CBM and other trenchless activities. GN Solids Control dispatched a 500GPM mud system to clients.
Firstly, remove the shaker box locking device of shale shaker GNZS703E-HB and mud cleaner GNZJ703E-D8N (Please refer shaker user manual and mud cleaner user manual for detailed operation). Then have a trial operation to shale shaker and mud cleaner.
All valves for pipelines are on off state after dispatch from the manufacturer’s factory. Before start up the system, operator should open values first and ensure all of them unblocked.

Then, start up shale shaker GNZS703E-HB and mud cleaner GNZJ703E-D8N. After the shaker and mud cleaner is running stably, start up submersible slurry pump to feed for the shale shaker. It is the first stage separation. When the mud reaches to three quarters of the 1# compartment underneath shale shaker (about 1 minute), start up the desilter feeding pump (1# sand pump GNSB6x5A-12J). Mud will be transferred to the mud cleaner 4’’ desilter cyclone from the 1﹟compartment, at a pressure of 0.25~0.40MPa. It is the
second stage separation. The clean mud from 4’’ desilter cone flow to the #2 compartment. When the mud height reaches to the overflow pipeline, it will overflow to #3 compartment. The user-owned mud pump is connected to the suction line of the 500GPM mud system tank and transfer qualified mud to wellhead. The clean mud can also directly flow to outside storage tank through the desilter output pipe.
When needed, users can start up the mixing pump (2# sand pump GNSB6x5A-12J) and feed to the mixing hopper GNSLS35A. The weighted mud from mixing hopper flows to 3# compartment. The suction port and discharge port of mixing pump are equipped with T-pipe, it can also mixing/discharge mud from/to outside tanks.  
Pay attention to the performance of the desilter cyclone. Ensure it works properly. If not, adjust the cyclone adjustment cap for a better performance. Pay attention to the figures on the pressure gauge of desilter cyclone, ensure it is under the scope of the working pressure. The working pressure of 4’’ desilter cyclone is 0.25~0.40MPa.

As China top manufacturing on mud solids control and drilling waste management, GN Solids Control exported complete set solids control equipment for Russia customer.
The projects includes below solids control equipment:
1) Solids control shale shaker with linear motion, model GNZS594E.
Model clarification: GN means brand. ZS means linear motion. 59 means the screen width is 59cm. 4 is 4-panel screens. E means it is the E generation from GN Solids Control.

It is a 4-panel linear motion shale shaker can be used for both solids control. It can also be used as high G drying shaker while equipped with 1.94Kw vibration motors and with hopper feeding.
GN offers steel frame screen and composite material screens for GNZS594E 4-panel shaker.
2) Fixed speed decanter centrifuges for solids control and barite recovery. Centrifuge model: GNLW363CG. It is the most popular side decanter centrifuge for drilling rigs.
GN and LW means the brand and centrifuge type. 36 is the centrifuge bowl diameter: 36cm. 3 is the bowl length and diameter ratio. 3 is the most popular ratio for drilling rig decanter centrifuges.
3) Some mud agitators and centrifugal pumps.
Even for the accessory small equipment, GN all made per international high standard, with all materials chose from internal and international famous brand.
For mud agitator, GN chose SOG oil seal and FAG genius bearings.
GN centrifugal pump is equipped with mechanical seal. The material for mechanical seal is tungsten carbon for long time. Bearings are from worldwide famous brand FAG.    
Other solids control equipments can be offered by GN Solids Control:
1) Desander, desilter or mud cleaner with under flow shale shaker. GN do offer 2-panel, 2-panel, and 4-panel under flow shale shaker.
2) Poor boy degasser, it is also name mud gas separator. It is used before shale shaker but after BOP to kill the gas in the mud.
3) Vacuum degasser. It is used after shale shaker but before hydrocyclone separator to kill the very small size gas to protect the cones.
4) Jet mud mixer for barite and polymer mixture.

GN Solids America LLC’s parent company, GN Solids Control
LTD located near Beijing, China, is the solids control machinery manufacture
who exports to sixty plus countries around the world’s oil and other drilling
regions.  With many other solids control
machinery manufacture by GN Solids Control LTD, the GNSL series jet mud mixer
is widely used paired with other solids control machinery and/or system.

GNSL series drilling fluid jet mud
’s purpose mixes the drilling
fluid to many different add chemicals to change the density and viscosity of
the drilling fluid. This drilling fluid machinery can meet the demand of the
fluid weighting and mixing of drilling solids control system for many kinds of
depth of drilling. Jet mud mixer structure contain of one centrifugal pump, one
feeding hopper and the control panel (optional). Frankly, the pipes and valves
connecting all these parts, the mud hopper use of the jet mud mixer is either
4“and 6”
opening for additive chemicals.

The inner wall boundary, cavitation and
erosion; swirl mixer pressure can’t bigger than 30% outlet pressure; the value
of mixer should operate in flexible, able to seal and reliable; each hoop and
flange joint should be properly sealed for reliable working order and don’t
have leakage. It is integrated with Ventura hopper and mechanical seal, jet
mixing pump which are connected with manifold valve. 

The drilling fluid jet mud mixer can assist
rig workers  to get the ideal drilling
fluid with good properties by adding bentonite clay, polymer and other chemical
powder additives. The pump, hopper  and
the control panel all can be installed on a single skid, or on the skid tank end or separately with the hopper on a tank
top and the pump at tank side. 

Centrifugal pump can also be called sand pump. It is widely used for oil and gas drilling rig mud system. It can be used as mixing pump, desander desilter feeding pump, centrifuge feeding pump, trip pump, charging pump etc…

There are different functions of centrifugal pump in oil and gas drilling rig mud system

1) Centrifugal feeding pump
Centrifugal pump can be used as feeding pump for desander, desilter and decanter centrifuge. It is normally mounted on the slope tank or skid of the mud tank.

2) Mixing pump
Centrifugal pump can be used together with mixing hopper as the mud mixing system. There are 2 type of mixing mud system with centrifugal pump.
One kind of design is both the centrifugal pump and mixing hopper with ventury are mounted on a separate skid, they are connected through pipes and values. And then connected to mud tank.
Another kind of design is more compact. It is built-in design onto the system. The centrifugal pump is mounted on the same tank skid, while the mixing hopper can be mounted on the tank top or on the tank skid.

3) Trip tank pump
Trip tank (5~10 cbm) is normally equipped for oil and gas drilling rig mud system. It is before shale shaker tank. And a small motor size centrifugal pump is requested for the trip tank.

4) Degasser pump
For European made vacuum degasser, it is not self suction type. A separate degasser pump is requested to generate vacuum for the degasser.
Unlike European brand vacuum degasser, GN Solids Control made degasser is self suction type. It does not need degasser pump. It can save the power of the total mud system.

Customer can also use centrifugal pump with other functions. GN Solids Control makes centrifugal pump from 15hp to 100hp, with size vary from 4×3 to 8×6 to suits for different applications.

GN Solids Control is certified for manufacturing of explosion proof control panel. Both the centrifugal pump and control panel can be mounted on the same skid for easy movement. If you need other customization, you can contact GN group for help.
