%X 自2012年我国开始进行大规模的页岩气商用开发活动以来，在页岩气水平井水力压裂过程中，套管变形问题频繁发生。尽管目前学者对其中机理进行了深入研究，但仍有很多问题亟待解决。本文在现有文献的基础上，对套管变形相关的研究现状进行了总结分析。结果表明，四川盆地页岩气开发中的套管变形率高于其他地方，且以剪切变形为主。影响页岩气水平井套管变形的主要因素有套管抗挤强度减弱、地质因素、水泥环质量、压裂施工参数等。本研究可为页岩气水平井水力压裂过程中套管变形的防治提供一定的参考。<br />
Since the large-scale commercial development of shale gas began in China in 2012, casing deformation issues have frequently occurred during the hydraulic fracturing process of shale gas horizontal wells. Despite in-depth research by scholars on the underlying mechanisms, there are still many unresolved questions. Building upon existing literature, this study provides a summary and analysis of the current research status related to casing deformation. The results indicate that the casing deformation rate in the Sichuan Basin shale gas development is higher compared to other regions, with shear deformation being predominant. The main factors influencing casing deformation in shale gas horizontal wells include weakened casing extrusion resistance, geological factors, cement ring quality, and fracturing construction parameters. This study can serve as a valuable reference for preventing and addressing casing deformation during the hydraulic fracturing process of shale gas horizontal wells.
