| Abstract:The Yunnan “hi-tech anti-drought well project” with pneumatic DTH and longitudinal slotted UPVC well pipe technology was introduced. The paper mainly presented the technical difficulties and drilling & well completion technologies of pneumatic DTH in the application for hydrological well in hard and broken bedrock, and according to the problems in drilling process, improvement measures were put forward to the drilling tool with obvious practical drilling effect. Drilling efficiency was improved in this project construction by DTH, the project cost was reduced, and the water output and quality also met the design requirement. |
