在我国的钻探施工过程中,经常会遇到一些复杂地层如力学不稳地层、水敏地层、渗漏地层等,为解决复杂地层施工中经常遇到的钻孔坍塌、落块甚至烧钻等问题,需要大力发展复杂地层的护孔工艺。基于此,本文在探究各种复杂地层的技术难题的基础上,制定相应的护孔方案,以期为我国钻探施工提供坚实的技术保障。
In China’s drilling construction process, often encounter some complex formations such as mechanical instability stratum, water sensitive stratum, seepage stratum, etc., in order to solve the complex formation often encountered drilling collapse, falling block or even burning drill Problems, need to vigorously develop the complex formation of the hole protection process. Based on this, on the basis of exploring the technical problems of various complex formations, the paper developed the corresponding hole protection scheme in order to provide a solid technical support for the drilling construction in China.
