Brief introduction for HDD

Horizontal directional drilling is called for short HDD, is a steerable trenchless method of installing underground pipes, conduits and cables in a shallow arc along a prescribed bore path by using a surface launched drilling rig, with minimal impact on the surrounding area.

Horizontal directional drilling is different with oil and gas drilling, water well drilling, etc. vertical drillings. So the mud process system or solids control system will be different also. The HDD mud process is called recycling since its point and issue is to recycle the drilling mud.

After processed by solids control equipments, some of drilling mud will be used again and some of waste subject will be treated accordingly or delivered to certain place for other application.

HDD working principle

HDD uses a drilling rig on the surface to install a drill pipe in a shallow underground arc. The drilling rig bores a pilot hole that’s filled with fluid and then uses a swiveling reamer to enlarge the hole to the final sewer pipe size. Sewer pipe is then pulled through the hole. Directional drilling often needs a large staging area so the pipe can be lined up before it’s pulled into the hole.

Main Components of HDD

1. Drill rig sized for the job at hand
2. Drill rods linked together to from a drill string for advancing the drill bit and for pulling back reamers and products.
3. A transmitter and receiver for tracking and recording the location of the drill and products drilling mud system
4. Drilling fluid recycling system
5. A pump for circulating the drilling fluid
6. Other components include bits, reamers, swivels and pulling heads

Mud cleaning system always contains shale shaker, mud cleaner, centrifugal pumps, mud agitator, mud tank, jet mud mixer, submersible slurry pump, electric control system, lighting system, ladder, slide walk, handrail valve, pipe line, clean gate, etc.
