油水井堵塞原因分析及解堵方案

Analysis of reasons for plugging of oil and water Wells and solution of plugging

通过深入分析油井堵塞机理,明确了固相粒子堵塞,采油作业系统及生产进度,污物堵塞以及外部流体-岩石失配对油井造成的影响。并以此为基础提出各种解堵方案,主要有化学解堵技术和物解堵技术。这些解堵方案经试验证明是可行有效的,可供油井工程参考使用。

Through in-depth analysis of the mechanism of oil well clogging,the effects of solid particle clogging,oil production system and production schedule,dirt clogging and external fluid-rock mismatch on oil well are clarified.Based on this,various plugging solutions are proposed,including chemical plugging technology and physical plugging technology.These plugging solutions are proved to be feasible and effective by experiments,and can be used for reference in oil well engineering.
