RC drill pipe 89/40mm Pipe Diameter R780 steel grade for water well
Product Description:
The high-pressure air and the gas pipe are transported to somewhere in the well. The high-pressure air and liquid are injected into the pipe through the mixer. Because the density of the mixed liquid is lower than that of the flushing liquid, the pressure difference between the pipe and the sample pipe causes the mixed gas and liquid to flow in the liquid. Under the action of the column pressure, it flows upward rapidly, and the cuttings particles are continuously brought out from the bottom of the hole to the ground.

Advantage
This series of reverse circulation pipes can increase the permeability of the lost stratum, reduce the consumption of drilling fluid, protect the reservoir stratum, and save the cost of other consumable tools. In addition, the pipeline can be drilled in two directions to control the drilling. The reverse circulation kill method can transfer heavy mud directly to the bottom of the well without periodic circulation, saving time.
