油田长停井复产探讨

Discussion of Recovery of Lasting Shut-down Oil-Water Wells

随着油田开发时间的延长,井况不良井、高含水井以及因其它因素引起的不能正常生产的油水井越来越多,长停井比例越来越大。大量油水井长期停产停注,一方面限制了油田采油注水能力,另一方面导致油田注采系统不完善,两者均严重制约了油田的高效开发和正常生产。通过对长停井状况、停产原因、复产潜力及复产方法等进行研究和探讨,旨在最大限度地利用现有资源和设备来提高油田油水井利用率,改善油田开发效果,提高油田经济效益。

Continuous development brings about more wells of bad condition,more high water-cut wells and more un-normal production wells,resulting in more lasting shut-down oil-water wells.Long shutdown of oil-water wells not only limits the oilfield injection-production capacity,but also leads to imperfection of its injection-production system,imposing restrictions on its high-efficient development and normal production.The purpose of discussing the conditions and reasons of long shut-down wells and their recovery potential and means is to furthest utilize the available resources and equipments to increase utilization of oil-water wells,improve development effect and gain more economic benefits.
