70 m 70 m drilling drilling rig structure structure consisting of machine: Trailed, vehicle type, vehicle type back machine. Generally composed of 70 m drilling machine: diesel engine, friction clutch, transmission, transfer case, drive shaft, mud pump, water pump, vacuum pump, turntable, faucets, winches, hydraulic system, control mechanism, mast, drill, car racks. Work drilling machine works 70 m 70 m drilling machine is pumping reverse circulation type. Its working principle is: the role of atmospheric pressure, circulating liquid by sedimentation through ring back to the ditch along the bottom of the wellbore flow gap, then the turntable drive drill, drill driven rotary drilling conducted by the mud pump aspiration to establish a negative pressure suction drill mud debris cavity, and then rose to 200 faucet drilling rig, mud pump into the sedimentation tank by circulating liquid precipitation continued to flow into the well bore after, again and again, forming a reverse circulation The drilling work. Well drilling rig industry toward higher direction rotary drilling rig has been developing rapidly in recent years, 200 drilling rig equipment, developing faster and faster, trends continue toward depth, capacity, efficiency, degree of automation direction 200 wells rig production lines, continuous development goals, so that the development of rotary drilling rig is getting better, after years of constant development, is now focusing on the development direction, is moving full hydraulic top drive power head in the direction of well drilling rig. Currently, the design, development, manufacture and application of rotary drilling rig, and are the first to achieve economic and practical, scientific and rational, high-speed and efficient production requirements, and time in production, but also according to the actual production needs rotary drilling rig will a variety of drilling rig equipment series grading operations where to sell 200 drilling rig, drilling rig after different grading operation, you can improve the basic parameters of the drilling rig, the formation of different series of standard drilling rig, which is the development of rotary drilling rig the goal. For rotary drilling rig, the standardization and serialization of production operations, are the basic steps to be traversed, the cornerstone of rapid development, so that rotary drilling rig in the right direction.
