HDD Solid Control
Horizontal directional drilling short name is HDD. HDD technology has the obvious in oil and gas pipelines crossing the rivers, lakes, highway, railway hub and other obstacles and important area. HDD site all is in the rivers, lakes, the traffic trunk line, neither dig in the excavation of large area nor make mud discharge randomly ; So it is very important to equip with mud recovery system.
HDD Mud Recycling System is made up of drilling rig mouth to return to mud of the ground through the mud into the mud pit, using liquid slurry pump or vertical sand pump the submersible supply to shale shaker,and then male the shale shaker removing out of solid phased particles, the processed mud fall into the mud tank having many separate space. Horizontal sand pump,making 1 # bulkhead mud supply to desander, and the mud through cyclone desander get rid of t 47-75 um solid particles. The processed mud fell into the mud tank bulkhead again, another horizontal sand pump, taking out mud and supply to desilter. Mud again through desilter processing, taking out more than 15 um of solid particles. The processed mud fell into the mud tank bulkhead, this time mud was already basic can be ready for using. If the mud weight is very high, also can using the centrifuge. But the centrifuge is not used generally in the HDD.
