应用气举反循环钻进工艺成功解决钻井施工疑难技术问题

Application of Air-lift Reverse Circulation Drilling Technology for Resolving Well Drilling Problems

摘要:

基岩钻井施工中，常规正循环钻进方法往往会遇到一些非常棘手的技术难题，使钻进施工几乎无法进行。介绍了应用气举反循环钻进工艺解决这些疑难技术问题的成功案例。

Abstract:

During well drilling in rock by conventional techniques, some involved problems are often met to stop drilling. The paper introduces the typical examples for resolving these problems by air-lift reverse circulation drilling technology.
