The Demand for Mud Treatment inHDD Mud Recovery System

Cuttings Removal: The broken cuttings are transported from the bottom of the hole to the surface to maintain the cleanliness of the borehole and prevent sand buildup that can hinder drilling.

Wall Protection: It stabilizes the borehole wall during the drilling process.

Lubrication: Mud serves as effective lubrication during drilling and pipe pulling, particularly in hard rock formations.

Cooling: Mud plays a role in cooling and flushing the drill bit or reamer.

Pressure Balancing: By adjusting the mud density, it establishes a liquid column pressure balanced with the formation pressure to prevent formation collapse.

Xi’an KOSUN’s HDD mud recovery system is developed and designed to meet the requirements of non-excavation technology both domestically and internationally.  It is used to purify and process the mud returning from underground during horizontal directional drilling processes.  Through solid control equipment such as shale shakers and cleaners, large-sized cuttings are separated.  The required mud materials are added and uniformly circulated through the mixing device to meet performance requirements for reuse.  The mud is then pumped into the horizontal directional drilling system for repeated circulation.  Xi’an KOSUN’s HDD mud recovery system significantly improves mud processing efficiency, reduces the mud cost of horizontal directional drilling, and greatly enhances drilling speed.
