1. Geological: before drilling to understand the types and distribution of geological, is the main geological strength, can is informed by geological report and core sampling geological limit bearing capacity, and the underground water level and deep pile diameter pile, etc., only after we fully understand the geology, mud to modulation, equipped with drill pipe drilling tool and tooth, using the appropriate operating mode.
2. Mud: the mud protects the drilling rig and ensures the quality of hole formation. After understanding the geological report, the mud is prepared according to the type and distribution of the ground quality and in combination with the geological strength and Party A's requirements.
