Water Well Drilling Method

The drilling machine is mainly used to develop groundwater resources, including domestic water, agricultural water and industrial water. At the same time, it is also suitable for hydro-geological exploration, construction engineering, bridge foundation drilling, etc. The structural forms of well drilling machine include traction type, vehicle mounted type and vehicle mounted back type. The general well drilling machine consists of diesel engine, friction clutch, gearbox, transfer case, transmission shaft, mud pump, clean water pump, vacuum pump, rotary table, faucet, winch, hydraulic system, operating mechanism, mast, drilling tool, frame, etc. The working mode of the drilling machine is pump suction reverse circulation type. Its working principle is that under the action of atmospheric pressure, the circulating liquid flows from the sedimentation tank through the return ditch to the bottom of the well along the annular gap of the well hole. At this time, the rotary table drives the drill pipe and drives the drill bit to rotate for drilling. The negative pressure established by the suction of the mud pump sucks the debris mud into the inner cavity of the drill pipe, then rises to the faucet, and is discharged into the sedimentation tank through the mud pump. The precipitated circulating liquid continues to flow into the well hole, and so on, Reverse circulation drilling work has been formed. The working mode of the drilling machine is pump suction reverse circulation type. Its working principle is that under the action of atmospheric pressure, the circulating liquid flows from the sedimentation tank through the return ditch to the bottom of the well along the annular gap of the well hole
