摘　　要：随着时代的不断发展,对天然气的需求越来越大,页岩气钻井作业项目也越来越多。然而,在页岩气井的实际钻井过程中,由于各种因素的影响,井壁稳定性导致的井眼坍塌事故时有发生,对工程作业产生重大影响。因此,笔者将在本文中探讨页岩气水平井井壁失稳的影响因素及对策,希望对页岩气的钻井作业起到积极的作用。Shale gas drilling projects are increasing as the demand for natural gas increases. However, in the actual drilling process of shale gas Wells, due to the influence of various factors, borehole collapse accidents caused by wellbore stability often occur, which has a great impact on engineering operations. Therefore, the author will discuss the influencing factors and countermeasures of shale gas horizontal well wall instability in this paper, hoping to play a positive role in shale gas drilling operations.
