Double Deck shale shaker and cuttings dryer for Africa drilling company

One set of double deck shale shaker and one set of vertical cuttings dryer are ready for shipment to Africa for drilling cuttings treatment system.
The double deck shale shaker will be applied as high G force drying shaker to separate the coarse solids, it can be used for both water based drilling cuttings and oil based drilling cuttings. The anti splash cover on the top to prevent the drilling mud from splashing. The top layer and bottom layer total 6pcs shaker screens are composite material frame for longer working life and better separation performance.


The vertical cuttings dryer is ideal equipment to be used for oil based drilling cuttings treatment, after treatment, the oil content on the cuttings is below 5%, the fluids will flow to an intermediate tank, then feed the fluids to decanter centrifuge for further treatment, the fine solids will be separated out by decanter centrifuge, the fluids can be reused for drilling. Before treated by decanter centrifuge, the fluids can be treated by drying shaker to reduce solids content, it will increase the decanter centrifuge treating capacity and performance, also it can prevent the centrifuge bowl from damaged by the high solids content.


GN standard drilling waste management system GNCM-40A is consist of VFD decanter centrifuge, vertical cuttings dryer, flushing pump, centrifuge feeding screw pump, fluids collection tank, skid, electric control system, accessories. The compact design with small footprint is loaded into standard container.
Except for drying shaker and vertical cuttings dryer, GN solids control also produce drilling waste treatment decanter centrifuge, including high speed decanter centrifuge, VFD decanter centrifuge, Fully Hydraulic Drive decanter centrifuge, we provide different explosion proof standard for option, IEC EX, ATEX, CNEX. For more information about high G drying shaker and vertical cuttings dryer, pls contact with GN Solids Control.

The vibration motor and starter is explosion proof and we have CNEX, ATEX, IEC EX for option. The bottom discharge trough and side discharge trough for option according to site condition. Also we can provide linear motion or elliptical motion shale shaker as per client’s requirement.


The shaker screen is fixed by wedge and operated from the outside of the shaker deck, it adopts mechanical synchronous adjustment for shaker deck angle, it is made of stainless steel for better corrosion resistance. Wear resistant polyurethane rubber strip on the shaker deck for better sealing performance. The detachable and fast open splash proof cover is to prevent mud splashing to keep the rig site cleaning.


The mud cleaner is a combination of desander cone, desilter cone and bottom shaker, the treating capacity is 500gpm, 1000gpm and 1500gpm for option. The shaker screen for bottom shale shaker is same with double deck shale shaker for convenient inventory.
Except for shale shaker and mud cleaner for offshore drilling, we can also provide decanter centrifuge, vacuum degasser, mud agitator, centrifugal pump, mud transfer pump and other solids control equipments.

 

Workover Drilling Rig Mud Tank System for Africa

Recently one set of workover drilling rig mud tank system are ready for delivery to Africa. The technical configuration is as below:
1. 2 units of GNZS594J-SHBJ 4 panel shale shaker with possum belly flow divider, 4 pcs of composite material frame shaker screen are installed on the shale shaker, as the primary separation equipment of the workover drilling rig mud tank system.


2. 1 unit of GNZCQ-270B vacuum degasser, self contained, no need extra jet pump. The vacuum degasser is suitable for various mud recycling system to separate gas from mud, the purpose is to remain the specific gravity and mud viscosity, also to protect the centrifugal pump from damaged from gas cut mud. Under the atmospheric pressure, the mud enters the rotor hollow shaft through the suction pipe and ejected towards the tank wall through the windows around the hollow shaft. Due to collision and the action of the separation wheel, a thin layer of drilling fluid is formed, causing the bubbles immersed in the mud to break and the gas to escape. Through the suction of the vacuum pump and the separation of the gas water separator, the gas is discharged to a safe area through the exhaust pipe, and the mud is discharged from the mud outlet by the centrifugal force generated by the impeller driven by main motor.


3. 4 units of GNJBQ055G mud agitators installed on the mud tank for agitating of drilling mud
4. 1 unit of GNSB3X2C-9J centrifugal pump
5. 1 unit of GNSLH-110C jet mud mixer with mud mixing hopper and 11KW mixing pump installed on the skid
6. 1 unit of GNZYQ1000A mud gas separator
