Description

114mm 4 1/2" remet double-wall pole reverse circulation


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. This drilling method has the advantages of high drilling speed, good hole quality, and less hole collapse in loose formations.
