HDD Mud System

 

What is HDD mud system

 

HDD mud recycling system is designed for Horizontal Directional Drilling (HDD) rig. Depending on drilling mud condition and recycling requirements, a HDD mud recycling system generally includes shale shaker, desander cyclone, desilter cyclone, decanter centrifuge, mud tank, mud agitator, mud gun, transfer pump and etc. How to decide the shale shaker scree mesh size depends on both the shale shaker performance in mud flow and the drilling mud separation at different mud requirement.

 

Working Procedure

 

1. There is a drill pit at each side of drilling hole. A set of vertical slurry pump will be on top of mud pit for feeding shale shaker. The shale shaker will separate drilling cuttings and discharge out, then the fluids will drop into sand trap through screen.

2. 1 or 2 or 3 sets of desander cyclone sit after shale shaker. One set of centrifugal pumps will feed desander cyclone for second phase separation. Solids out of desander will be discharged to shaker screen or the cutting box directly and fluids over flow from desander will flow into desander compartment.

3. A quantity of desilter cyclones will sit after desander for fine solids separation. Solids out of desilter will be discharged to shaker screen or cuttings box and fluids over from desilter will drop into desilter compartment.

4. A mixing pump sit on tank skid for drilling mud transfer and feed mud into mud hopper for new mud remix by new chemicals. The mixing hopper can sit on top of tank or tank skid as per client’s demand.
