HDD is short of horizontal direction drilling, this is widely used in municipal project and also oil gas industry for pipeline laying etc. In most HDD project there will generate large drilling sludge, in some special project, these slurry also mixed much chemical medicine to improve the drilling efficiency and protect the rig. However these slurry is very expensive and also has big pollution to environment if we directly dump. Recycle the involved slurry in drilling sludge is very necessary to reduce the drilling cost and protect environment.

Last week we delivered one set HDD mud reclaimer to abroad project. This system include 2 unit GN mud recycle and one unit mud mixing tank. GN mud recycle unit is a small comprehensive system, which equipped GN shale shaker, hydrocyclone and also mud tank. This is double deck shaker, sludge was feed on the bottom shaker first, which can remove out the big size particle, liquid through shake screen and down to bottom tank. Centrifuge pump transfer slurry from tank into hydrocyclone, under the rotating liquid flow, solids will discharged from bottom of hydrocyclone , and recycled liquid will discharged out the system from top end, this discharged liquid is clean enough for reusing. Solids discharged from cyclone will drop on top layer shaker screen. This screen is higher mesh to separate out small size particle, liquid go through top and bottom shaker screen , finally down to bottom tank. Centrifuge pump it again into hydrocyclone. After a entire loop treatment, we get clean slurry and dry solids.

In this project, we also customized produce mud mixing tank for client mad drilling mud. From photo you can see it has big tank to store cleaner water and also a feeding hopper. Pump water from tank, through venturi principle, chemical medicine will be feed from hopper and mix with water. This design is convent for client to supplement new mud when they need.

GN has more than 15 years manufacture experience in separation equipment.If your project have demand on this kind equipment ,welcome to contact us.
