摘　　要：随着采出水注入开发时间的延长,高压欠注井日益增多,近几年已成为影响油藏开发效果的主要因素,针对此类开发矛盾,实施了注水井降压增注措施效果分析及评价,通过不断的工艺改进、对比、分析及评价,近几年实施的新工艺降压增注效果较好,为后期油田开发的欠注井治理工作开启了新思路。With the extension of the development time of produced water injection,the number of high-pressure under-injection wells is increasing,which has become the main factor affecting the reservoir development effect in recent years.In view of such development contradictions,the effect analysis and evaluation of depressurization and injection increase measures for water injection wells have been implemented.Through continuous process improvement,comparison,analysis and evaluation,the new process implemented in recent years has achieved good results in depressurization and injection increase.It opens a new idea for the treatment of under-injection wells in later oilfield development.
