What method is used for the operation of a water well drilling rig
The working process of water well drilling rig is inseparable from the use of pump, which is used for reverse circulation operation. 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, which goes on and on, Reverse circulation drilling work has been formed. Mud or water enters from the drill pipe and flows out from the wellhead. It is a positive circulation drilling machine. Mud or water is sucked out from the drill pipe and flows in from the wellhead. It is a reverse circulation drilling machine. Positive and negative circulation refers to the circulation mode of drilling fluid in the drilling machine. It is said that the drill bit of the drilling machine will produce muck, slag and stone during drilling, which can be brought out by mud through positive and negative circulation.
