辽河油田带压修井作业技术现状与应用

Current Situation and Application of Workover Treatment under Pressure in Liaohe Oilfield

目前国内共有油水井21.6万口,年修井量在20万井次以上,且每年以近2万井次速度增长。如此浩大的作业量普遍采用常规修井技术施工,即采用放喷降压和洗压井方式作业,对油气田开采成本和环境影响构成了巨大的压力。辽河油田自主研发的带压修井工艺技术,正是转变发展方式,改进作业手段,走高效、低耗、零排放的一项最佳采油工程技术。

Currently in China, there are a total of 216,000 oil-water wells, workover wells are more than 200,000 every year, and growing rate nearly 20,000 wells every year. The conventional workover technology is used in workover, namely blowout and pressure-relief and pressure washing treatment, which affects the cost of extracting oil and gas fields and the environment. The workover treatment under pressure researched and developed by Liaohe Oilfield is a best oil recovery engineering technology with changed treatment way, high efficiency, low energy consumption and zero release.
