Mud Treatment in Directional Drilling Construction
Horizontal directional drilling machines operate using a cantilevered method, where the drill bit is laterally excavated to the desired drilling position through a guidance system. As the drill bit rotates, it is hydraulically advanced using a drill stem. This method enables the drill bit to progress in the required direction, continuously expanding the diameter of the borehole to the desired size.
Applications of horizontal directional drilling machines include:
Foundation engineering and metro tunnel construction
Treatment of mud generated during directional drilling construction:
Mud is a necessary material in the process of horizontal directional drilling, used to carry cuttings back to the surface, cool the drill bit, and provide lubrication. Mud is a mixture of bentonite and water in certain proportions. Xi’an KOSUN’s mud recovery system is designed to remove sand and silt from the returned mud for the purpose of reuse. Reusing the mud can reduce the amount of residual mud that needs to be processed. The primary material filtered out by the recovery system is drill cuttings generated from cutting through rocks, consisting mainly of sandstone, mudstone, siltstone, and shale fragments. These are classified as category II solid industrial waste, with no significant environmental hazards. After completion of the project, the remaining drill cuttings are transported by specialized vehicles to designated locations specified by the environmental protection department and processed according to their specific requirements.
