Working Process Of Water Well Drilling Rig

Water well drilling rig is a convenient, efficient and multifunctional rock drilling equipment. it can be used for air, foam or mud to make rotary or impact drilling according to different geological conditions. water well drilling rig is widely used in agricultural water conservancy projects, drilling rock wells, testing wells and other exploration wells, especially for geothermal heating holes.

The operation of the water well rig is inseparable from the use of the pump. It mainly uses a pump for reverse circulation operation. Under the action of atmospheric pressure, the circulating fluid flows from the sedimentation tank to the bottom of the well along the annular gap of the wellbore through the backwater channel. At this time, the turntable drives the drill pipe to drive the water drill bit to rotate and drill. The negative pressure established by the mud pump draws the debris mud into the inner cavity of the drill pipe. Then it rises to the faucet and is discharged into the sedimentation tank through the mud pump. The circulating fluid after the sediment continues to flow into the wellbore, so that the well drilling rig forms a reverse circulation drilling operation.
