威远页岩气水平井压裂套变原因分析

Analysis on the causes of fracturing jacket variation in Weiyuan shale gas horizontal well

本文对页岩气水平井的压裂过程做了深入分析,同时结合威远地区储层的地质特点,利用现有的水平井压裂套变资料,对套变产生的特点和导致套变问题出现的原因进行了深入分析。希望借助此次研究能够给套变预测以及预防提供一定指导。

This paper makes an in-depth analysis of the fracturing process of horizontal shale gas Wells.At the same time,combined with the geological characteristics of the reservoir in Weiyuan area,using the existing fracture casing data of horizontal Wells,the characteristics of casing deformation and the reasons leading to the occurrence of casing deformation are analyzed in depth.It is hoped that this study can provide some guidance for the prediction and prevention of nesting changes.
