本刊讯为提高深井钻探施工效率和经济效益,在深井钻探技术工艺方面有所突破,贵州省地矿局成立了深井钻探技术攻关领导小组,加强对新技术新工艺攻关的领导。攻关小组参考国际、国内先进钻井工艺,结合贵州地层裂隙溶洞发育、破碎、软硬互层、水文地质情况复杂等特点,选定应用空气钻井(空气欠平衡钻井技术和空气潜孔锤钻井技术)和螺杆钻井新工艺,同时研究适合贵州地层的泥浆技
In order to improve the efficiency and economic benefits of deep well drilling construction, a breakthrough has been made in deep well drilling technology and technology. Guizhou Provincial Bureau of Geology and Mineral Resources has established a leading group for drilling deep well drilling technology and strengthened its leadership in tackling key problems related to new technology and new technology. With reference to the international and domestic advanced drilling technologies, the research team selected the application of air drilling (air underbalanced drilling technology and air hammer drilling technology) based on the characteristics of crack formation, fracturing, hard and soft interbedded layers and complicated hydrogeology in Guizhou. And screw drilling new technology, at the same time for the study of Guizhou formation mud technology
