河南油田采油二厂注入井套损原因初探

A Preliminary Study on the Causes of Casing Damage in Injection Wells of the Second Oil Production Plant of Henan Oilfield

河南油田注水老区,随着开发的不断深入,油田注入启动压力也逐年提高,在井底高压的条件下,注入井套管缩径、套漏、错断的情况也逐年增加。主要从地质和工程方面综合研究分析河南油田采油二厂注入井套损原因,为下一步套损防范措施提供理论依据。

In the old water injection area of Henan Oilfield,with the continuous development,the injection starting pressure has risen. The cases of injection well casing shape reduction,casing leakage and casing collapsing,which the excessive injection pressure caused,has also increased. This thesis aims to comprehensively research the causes of casing damage in the injection wells of the second oil Production Plant of Henan Oilfield from the aspects of geology and engineering,which lay foundation for further research of measures of casing damage prevention.
