空气钻进技术及其在内蒙古供水井施工中的应用

Application of Air Drilling Technology in Water Supply Well Construction in Inner Mongolia

摘要:

空气钻进技术可以极大提高钻进时效, 同时也可以降低钻井的整体施工成本。目前空气钻进技术不断完善并广泛应用于钻井施工中。对空气钻进的应用情况作了简要的介绍，对主要设备及工艺流程等作了一定描述，着重强调了空气钻进的优缺点。特别是针对内蒙古自治区东部区阿荣旗部分区域玄武岩层坚硬、严重井漏问题成效明显，获得了很好的技术与经济效益。

Abstract:

By air drilling technology, drilling efficiency can be greatly improved and the drilling construction cost can be reduced at the same time. At present, air drilling technology is continuously improved and widely used in drilling construction. The paper briefly introduces the application situation of air drilling technology, describes the main equipments and technological process and emphasizes the advantages and disadvantages of air drilling. The application effects are obvious in some parts of the eastern Inner Mongolia Autonomous Region, where there are hard basalt rocks and severe lost circulation.
