气举反循环钻进工艺在3512 m深的京热164号井中的应用

Application of Airlift Reverse Circulation Drilling in Jingre 164# Well of 3512 m Depth

摘要:

经过多次的技术改革和生产实践的检验，气举反循环钻探工艺目前已成功钻进至3512 m深度。与泥浆正循环相比，体现出了高效率、低成本和利于洗井、成井的特点，解决了目的层漏失的问题。

Abstract:

Through many times of technical innovation and production practice, 3512 m drilling depth has been achieved by airlift reverse circulation drilling technology. Compared with the slurry positive circulation, leakage in target layer is controlled with higher efficiency, lower cost, easy wellwashing and completion.
