| 中文摘要: |
| 20世纪 80年代，空气反循环连续取样技术( RC)作为多工艺空气钻探技术之一，被我国地矿部列入“七五”和“八五”国家科技攻关项目，自此开始了 RC技术引进和设备国产化科研攻关的进程。有色金属矿产地质调查中心率先引入了国产化设备，进行 RC钻探实践工作，依托于国产化设备、双壁钻杆等，有色金属矿产地质调查中心在国内外多个地勘项目中进行了 RC钻探的实际应用，对设备配置、工艺参数、操作技术、钻具级配等进行了探索和完善，形成了一支完备的 RC钻探施工力量。 |

| In the1980s, RC, as oneof the multi-process air drilling technologies, was included in the“Seventh Five Year Plan” and “Eighth Five Year Plan” National Science and Technology Project by the Ministry of Geology and Mineral Resources. Since then, the process of RC technology introduction and equipment localization research has begun. As a subordinate unit of the former General Bureau of Geological Survey of China Nonferrous Metals Industry Corporation, China Non-ferrous Metals Resource Geological Survey took the lead in introducing localized equipment to carry out RC drilling practices. Relying on localized equipment, double-wall drill pipes, etc., the company has carried out practical applications of RC drilling in a number of geological exploration at domestic and foreign projects, and explored and improved equipment con.guration, process parameters, operating technology, drilling tool grading, etc., Forming a complete RC drilling construction force. |
