6BS 6BS gravel pump+6” centrifugal pump
1.It is suitable for drilling various industrial and agricultural well engineering, construction foundation, bridge foundation, oil field casing pipe, high pressure line pile, port wharf and dam foundation in Quaternary loose strata loose and gravel layer.
2.The rig uses mud as the flushing liquor with 6BS gravel pump to drill; the equipped vacuum pump system provides water for the gravel pump.
The rig equips with hydraulic system, hydraulic tower, hydraulic supporting legs.
3.The drill pipe is screw thread joint, with special unloading device, easy to change the drill pipe.
4.The appearance of rig is pretty; it has a high efficiency because of having larger torque; it is suitable for water well engineering, construction, building, bridge foundation, port, dam and so on; it is popular with the domestic and foreign clients.
5.The top head:
The power head is driven by two high-torque hydraulic motors. The spur gear three-stage reduction system (reduction ratio is 64), the central shaft can output low speed. At the same time, the torque is increased to meet the needs of large-diameter drilling. The power head core tube is sealed by a set of V-shaped rubber rings to ensure the airtightness of the pipeline. This power head can also be used as a drilling pressure counterweight to improve drilling efficiency in slipping formations.
Main functions of drilling:
1. Obtain underground physical data and obtain core, cuttings, oil, water, natural gas, etc. from the bottom of the well.
2. As a geophysical logging channel, obtain data on various geophysical fields of the rock formation, such as underground military fire tests.
3. As an artificial channel, observe the mineral, hydrological and geological structures in the stratum.
4. Comprehensive application, comprehensive exploration and acquisition, and the use of underground resources.
