This is a new kind of drilling rig designed and produced by our company. It is driven hydraulically for drilling and hoisting operations via gears and toothed racks and it is unnecessary to use drawworks, wire line, travelling block, hook block, and rotary tables on the drilling rig. Due to the simple design, it is easy to maintain and has a long working life. This kind of drilling rig is suitable for under-balance drilling, slim-hole operation, general workover/service, snubbing operation, heavy drilling operation and side tracking etc.
This kind of drilling rig is equipped with a hydraulic power end, hydraulic pipe handling tools and other automatic tools which can reduce heavy labor and achieve safety and high efficiency.
