mud mixing system

This week GN solids control shipped 2 sets of HDD mud recycling & mixing system to India client for their HDD projects. This is not the first order from the HDD contractor, they bought the 350gpm mud recycling system and 500 gpm mud recycling system several years ago for their Vermeer rig. The technical configuration is as below:


One mud tank 9000x2300x2150mm which is customized design size to meet their storage capacity requirement. For compact design and better mud cleaning performance, we installed the double deck shale shaker with desilter cones to meet the client’s capacity requirement. A centrifugal pump as feeding pump of the desilter cone, one centrifugal pump as mixing pump for the venturi hopper. The mud agitator and mud gun installed on the mud tank for agitating the drilling mud and prevent the solids from silting. An extra submersible slurry pump is equipped as the feeding pump of the mud recycling system from the mud pit.
Features of the 2 sets of mud recycling system:
1) Compact design with the biggest storage capacity as per the client’s requirement
2) Container loading size for convenient transportation and cheaper sea freight cost
3) Mechanical seal centrifugal pump, the impeller and pump casing material is made from hard ductile iron alloy, increased abrasion resistant capability.


4) Double deck shale shaker with desilter cone for 2 phase cleaning and increase the reating capacity.
5) Pretensioned shaker screens with composite material frame for longer working life and better separation performance.
6) Explosion proof electric control system for better rain proof, sun proof and dust proof.

Right now, in GN head quarter near Beijing, in the ware house, there is a set of oil drilling mud system ready for shipment. This is a drilling mud system for a ZJ50 land rig and it will be used for India Drilling. This is for a complete drilling mud system with all necessary separation phases, the 4 phase of clarification and 5 phases separation.

The equipments in this drilling mud system include following:

  1. shale shakers of 3 sets, they are connected directly to the mud distributors and worked at same time. They are located on shaker tank. Recommended GN shale shaker.
  2. vacuum degasser, it follows the shale shakers and will be used to separate out the air bubbles from the drilling mud, it also plays a role as a big mud agitator and it helps to protect the centrifugal pumps for feeding the desander and desilter and also enhances the working efficiency of the hydrocyclone feeding pumps.
  3. desander and desilter, respectively of 10 inch cyclones and 4 inch cyclones. Recommended GN desander and desilters.
  4. decanter centrifuges, they are used for recovering the barite and for extra fine particles separation.

Besides mud solids control system for oil and gas drilling, mud plant, oil and gas waste management systems for drilling mud and drilling cuttings, GN products also covers the mud mixing  systems for the HDD drilling, CBM drilling, TBM projects and water well drilling. And some of GN clients are using GN Solids Control’s equipment in their industry sludge separation works.

In each year, GN engineer team makes new improvements for the existing equipments and also design and put into reality the new equipments to feed the new standard for the environment protection or the requests from the clients and end users. That’s why GN’s products such as shear pump, Mud Gas Separator , mud agitator , Vacuum Degasser ,etc. and fame are becoming better and better. In the past year, GN has put into use the solidification unit for the oil based mud cuttings and end users from both domestic and abroad give good feedbacks.
