◆ Product introduction ◆
➣It integrates mud drilling, air drilling and foam drilling, and is equipped with complete air drilling equipment and other geothermal well testing equipment to meet the requirements of multi-mode geothermal well drilling process;
➣It can realize the step-by-step guide rail sliding cluster well, and the mast hydraulic cylinder can be moved quickly;
➣The mast and substructure can rise by multi-stage hydraulic cylinder, which can be operated remotely;
➣Equipped with automatic pipe handling system (PRS), power elevators, iron roughneck and other automation equipment to reduce work intensity.
➣Equipped with ahigh-voltage room, so the drilling rig can obtain electricity from the industrial grid.
