HDD Mud Recycling System

HDD mud recycling system is design for Horizontal Directional Drilling ( HDD ) rig. Depending on drilling mud requirement, a HDD mud recycling system can including shale shaker, desander cyclone, desilter cyclone, decanter centrifuge, mud tank, mud agitator, mud gun, transfer pump, etc. The shaker screen mesh size will depending on a shaker performance for mud flow and drilling mud separation at different mud requirement.

HDD Mud Recycling System Working Procedure

1. 1. There is a drill pit at each side of drilling hole, a set of vertical slurry pump will set on top of mud pit for feeding shale shaker. The shale shaker screen will separate drilling cuttings and discharge out, fluids part will drop into sand trap through screen hole.
2. 2. 1 or 2 or 3 sets of desander cyclone sit after shale shaker, one set of centrifugal pump will feed desander cyclong for second phase separation, solids out of desander will be discharge to shaker screen or cutting box directly and fluids over flow from desander will flow into desander compartment.
3. 3. A quantity of desilter cyclones will sit after desander for fine solids separation, solids out of desilter will discharge to shaker screen or cuttings box, fluids over from desilter will drop into desilter compartment.
4. 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.
