摘要

地质钻探成本高,选址较难,所以对单孔成井有较高的要求,而钻探施工常常会发生一些事故,不仅会造成较大的经济损失,而且对后期使用也有一定的影响。本文中结合实际工作经验,系统的分析了在泥页岩地层中钻进造成井塌事故的原因,并提出合理化建议及时做出预防措施。
        Geological drilling costs are high and location is difficult, so there are higher requirements for single hole completion, and drilling construction often occurs some accidents, which will not only cause greater economic losses, but also have a certain impact on later use. In this paper, combined with practical work experience, the causes of well collapse accidents caused by drilling in shale formation are systematically analyzed, and reasonable suggestions are put forward to make timely preventive measures.
