油田开发后期强化注水工艺技术

在油田注水开发的后期,油井的含水率随注水量增加而升高,注水井与采油井的连通状态发生动态改变,产量进入快速递减阶段,因此必须动态监测油水情况,实施有助于提升油田采收率的措施和工业技术,才能减缓产量递减速率,使油井维持长期稳定生产能力,获取油气产能的最大效益,达到开发后期油藏生产指标。本次对开发后期油藏开采工作中所面临的难题进行了相应的分析,以提高剩余油的开发率,达到油田开发指标。

Enhanced water injection technology at the later stage of oilfield development

in the late stage of oilfield water injection development, moisture content increased with the increase of water injection Wells, injection Wells and production Wells connected state of dynamic change,production has entered into the phase of rapid decline, dynamic monitoring oil and water, so you must help to improve oil recovery measures and industrial technology, in order to slow down production decline rate,make the well to maintain long-term and stable production capacity, achieve the maximum benefit of the oil and gas production capacity, the goal of maximizing the oilfield development economy. Therefore, this paper mainly aims at the problems occurred in the later stage of oilfield development, and studies the enhanced water injection technology in the later stage of oilfield development and production, so as to improve the development rate of remaining oil and reach the oilfield development index.
