渤海X油田注水井酸化问题分析及改进探讨

Analysis and Improvement of Acidizing of Water Injection Wells in Bohai X Oilfield

渤海X油田是注水开发油田,随近年油田提液生产,注水需求逐渐增加,注水井欠注问题愈加严重。通过对比近年注水井重复酸化后的增注效果变化情况,分析X油田注水井酸化增注措施存在的问题,并且据此提出针对性改进建议,为油田后期注水井酸化增注提供借鉴。

Bohai X oilfield is a waterflooding oilfield.With the increase of fluid production in recent years,the demand for water injection gradually increases,and the problem of under injection of water injection wells becomes more and more serious.By comparing the effect of increasing injection after multiple acidizing of injection wells in recent years,the problems existing in acidizing and increasing injection measures of injection wells in X oilfield were analyzed,and corresponding improvement suggestions were put forward,so as to provide some reference for acidizing and increasing injection of injection wells in later stage of oilfield developmemt.
