Mud Recycling Unit for overseas Trenchless Projects

Recently several sets of mud recycling system are ready for shipment to overseas trenchless projects.


The trenchless mud recycling system is a specialized equipment setup used in horizontal directional drilling (HDD) and other trenchless technologies. Its primary function is to clean drilling fluids (commonly known as mud) during the drilling process. The purpose is to use the trenchless mud recycling system is that the recycling drilling fluids can be used to lubricate the drill bit, stabilize the borehole, and carry cuttings back to the surface. These fluids need to be constantly circulated and maintained to ensure efficient drilling and environmental compliance.


Environmental Benefits: Recycling systems help minimize waste and reduce the environmental impact of HDD operations by reusing drilling fluids.
Operational Efficiency: By continuously recycling and maintaining drilling fluids, these systems contribute to the efficiency of trenchless drilling operations, reducing downtime associated with replacing fluids and improving overall productivity.
The basic configuration of a mud recycling system is consists of primary shale shaker, mud cleaner, feeding pump, centrifugal pump, mud agitator, decanter centrifuge, mud tank, etc.


The compact design mud cleaning unit consists of double deck shale shaker with hydrocyclones, the bottom layer shaker screen works as primary shale shaker to separate coarse solids from the drilling mud, the clean fluids dropped into the intermediate tank, the feeding pump feed the mud to hydrocyclones for second phase cleaning, the top layer shaker screen as mud cleaning drying screen to recycle more fluids. The clean fluids flow to client’s storage tank or mixing tank to prepare for new drilling fluids.
The hydrocyclone size is for optional for different applications, for TBM and Pilings, 10 inch, 12 inch or 20 inch can be selected; for HDD applications, 10 inch, 4 inch can be used. For more information, pls contact with GN solids sales.

 

Mini Desander and Desilter for Africa Drilling Company

Recently one batch of mini desander and mini desilter are ready for shipment to Africa drilling company. The technical configuration is as below:


The mini desander unit consists of 2ea 10 inch desander cone and mini bottom shaker drived by explosion proof vibration motor. GN own produced composite material frame shaker screen are produced comply with API RP13C standard. The mini desilter cone consists of 16ea 4 inch desilter cone with mini bottom shaker.
Generally, the combination of hydrocyclones above 6 ″is called desander, which is a secondary solid control equipment in drilling operations. 10”and 12”cones are commonly used to separate the particle size of drilling fluid from 44-74μm solid particles.
Compared with the desander and desilter without bottom shaker, the mini desander unit and mini desilter unit with bottom shaker can recycle more drilling fluids and dry the drilling cuttings, it can be installed after primary shale shaker on the solids control system.


Except for mini desander unit and mini desilter unit, GN also produce desander, desilter and bottom shaker 3 in 1 mud cleaner. By use different qty desander cone and desilter cone, the mud cleaner with 500gpm, 1000 gpm, 1500gpm treating capacity.
Features of GN mini desander, mini desilter, mud cleaners are as below:
1. Composite material frame screen and wedge type screen pressing device are applied for fast screen replacement.
2. International brand vibration motor , Martin motor or OLI motor is adopted.
3. International famous brand electrical components, Siemens or Schneider components.
4. The shaker deck bottom with a patented sealing design, with good sealing effect, long service life and easy replacement.
5. The shaker deck angle is adjustable mechanically synchronously, which is convenient and reliable.

Centrifugal Pump and Solids Control Centrifuge for Africa Client

Recently 2 set of 1500HP drilling rig solids control equipments are ready for delivery to our Africa client. The equipments list including:


6 units of GNZS594J-SHBJ linear motion shale shaker, which is a single deck 4 panel high G force shale shaker. 3 units shale shaker per rig, total treating capacity can reach at least 1500gpm. The shaker screen installed on the shale shaker is produced compliant with API RP 13C standard. Not only for OEM shaker screens for GN own shale shaker, we also produce replacement shaker screens for world famous brand shale shaker. Pls contact with GN solids control for more information.


3 units of GNZJ594J-2S12N linear motion mud cleaner, the bottom shale shaker is same with the linear motion shale shaker, combined with 2 ea 10 inch desander cone and 12 ea of 4 inch desilter cone, the treating capacity is up to 1000gpm. It can be also act as back up shale shaker if required.
16 units of centrifugal pump, the centrifugal pump can be used as feeding pump of desander cone and desilter cone, it can be also used as trip pump, mixing pump, transfer pump, super charging pump.


2 units of GNLW452 decanter centrifuge, this is a middle speed decanter centrifuge which can be used for barite recovery, the separation cut point is 5~7 microns. If for low gravity solids separation, we can utilize high speed decanter centrifuge to separate the fine solids, or VFD decanter centrifuge can be introduced to be used for both barite recovery and LGS separation.


Except for the above equipments, GN solids control also provide vacuum degasser, mud agitator, mud gun,mixing hopper, mud gas separator, mud tank system, etc. We also provide decanter centrifuge, vertical cuttings dryer, high G drying shaker , screw conveyor, etc. drilling waste management equipments.
