Underground directional drilling theory
Sep 05, 2017

Underground directional drilling technology is based on real-time regulation of the dip angle and azimuth to accomplish precise control of borehole trajectory. It can ensure the borehole trajectory effectively extend in the objective layer, and can be carried out many sidetracks construction.

The system  consists of capable directional drill rig, downhole motor, real time survey tools (MWD), modular electrical connected cable assembly (MECCA) drill rod and mud pump crawler. 

The system has capable for sub-horizontal precise directional drilling operations with borehole depths of 1500 meters, and has been widely used to drill boreholes in gas drainage, water hazard control, geological exploration and other accurate drilling fields.
