mud mixing tank

Recently one unit of GNMS-1000D HDD desander plant and GNMS-500D HDD desander unit, one unit of dewatering centrifuge GNLW554E-VFD, three set of mud mixing and storage system, one unit of jet mud mixer are shipping to engineering company.


The HDD/ TBM desander unit are a compact design mud cleaning system, the technical configuration is as below:
Double deck shale shaker with hydrocylones as 2 phase cleaning equipment, the first phase cleaning is coarse solids separation shaker screen, normally we use API 40 or API 60 shaker screen; the second phase cleaning is fine solids separation by desander cone, the solids are drop down to the fine mesh shaker screen to collect more useful fluids. One feeding pump for desander cone are installed on the compact mud tank with electric control panel, cable connection, pipelines and accessories. The cut point of the desander unit is 40 microns. The GNMS-500D desander unit with one unit of desander cone, the treating capacity is 500gpm; GNMS-1000D deander unit with 2ea desander cone, the treating capacity is 1000gpm. The shaker screen installed on first layer and second layer are both composite material frame shaker screen, the screen locking way is by wedges.


The dewatering centrifuge GNLW554E-VFD is used after the desander unit, the separation cut point is 2 microns, it can separate most of the fine solids, the big bowl big volume decanter centrifuge can meet the requirement of big tdewatering capacity, the recovery fluids will be storage at the 3 mixing & storage tank, the jet mud mixer can mix the fluids with powder chemicals to prepare for new drilling fluids, which can be reused to save drilling cost. The pipelines between 3 mud tanks are in parallel connection, so that the jet mud mixer can mix in any tank. Each tank with its mud agitator for better mixing.

Recently one set of liquid mud plant are ready for shipment to South America. It is one of the three components of the complete liquid mud plant for this client, the client take this part as first phase project, it consists of mud mixing tank and storage tanks.


The mud mixing system is a square tank with 400bbl capacity, two each of special designed dust free mixing hopper are vertical installed on the mud tank and drived by 2 units of slurry pump for mud mixing. 2 units of mud agitator are agitating the mud to prevent it from precipitation in the tank bottom, the mud gun are installed as mixing and transfer of mud which is drived by centrifugal pump. The tank accessories including hand rails, pipeline, valves, walkway, stairs, and one unit of operation table, there is a stair to walk on and easily take the dry bulk chemicals and put it on the mixing hopper.


The mud storage system including 14 units of cylinder tanks in 2 rows and connected by pipelines and controlled by valves, the gun line outside the cylinder tank to transfer the mud flexible. The mechanical liquid level meter outside the vertical tanks can easily check the mud level by the operator.
2 units of centrifugal pumps are installed on both end of the storage system and connected by pipelines as transfer pump, they can transfer the mud from any storage tank to mixing tank, and transfer mud from mixing tank after mixing to any storage tank. All the gate valves, bufferfly valves, and all the rubber parts in the system are all oil resistant material for longer working life. The system color is customized blue color, we can also paint with client’s LOGO if required.
