| Abstract: | It has been proved by a construction test that by means of air foam DTH drilling, the borehole structure can be optimized and drilling parameters can be adjusted to improve ancillary equipments and construction technology. Especially rapid cuttings discharging can be realized for large diameter deep bedrock wells in drought and water shortage area, which can further improve the drilling efficiency to have higher market competition ability. |
