摘　　要：为了解决X气田开发当中超深水平井水平段长、非均质性强、裸眼完井实施机械封隔风险大、笼统改造不能实现均匀酸化等问题,进行多级暂堵转向酸化研究。基于暂堵转向酸化作用机理,探索多级暂堵转向酸化工艺,利用可降解暂堵剂对高渗储层进行暂堵,使酸液转向,从而实现整个长水平段的均匀布酸。This thesis aims to solve the problem of ultra-deep horizontal well in X field brought by the long horizontal segment,the strong heterogeneity,the risk in using mechanism packers for the open hole completion and the difficulties for the uniform acid distribution. On the basis of temporary blocking of the steering mechanism of acidification,this paper explores a multi-level steering temporary blocking acidification process,which uses the biodegradable temporary to block the hypertonic reservoir,making the diversion in order to achieve a uniform distribution acid-fracturing for the long horizontal segment.
