岩芯钻探技术中的护壁堵漏方法

Breast Wall Plugging Method in Core Drilling Technology

在钻探工程中,护壁堵漏问题一直是业界的难题,尤其是针对复杂地层的钻探工作,更是为护壁堵漏工作增加了难度。本文立足于实践,对复杂地层岩芯钻探的护壁堵漏问题进行了分析,并对其护壁堵漏方法进行了实践探讨,希望能够对相关工作人员有所启发。

Breast wall plugging has always been a difficult problem in drilling engineering, especially for drilling work in complex formation, which increases the difficulty for plugging and protecting work. Based on practice, the breast wall plugging problems of complex formation core drilling are analyzed, and the breast wall plugging methods are discussed. It is hoped that this paper can provide some reference for the related staff.
