安塞油田长10油藏于2009年开始采用大规模注水开发,从近几年开发效果来看总体形势较差,表现出见水速度快,自然递减率大的特点。为提高油藏开发效果,2012年开始通过室内细管驱替实验,分析认为注气要好于注水开发效果,随之在油气比较高的高52井区进行试验,并取得了阶段性的注气开发经验和认识。
The Chang-10 reservoir of Ansai Oilfield started to develop large-scale waterflooding in 2009 and the overall situation is poor in terms of the development results in recent years. It shows the characteristics of quick water seepage and large natural decline rate. In order to improve the reservoir development effect, the indoor thin-tube displacement experiment was started in 2012, and the gas injection is considered to be better than the water injection development effect, followed by the test in the high oil and gas high-52 well area and the gradual gas injection Develop experience and understanding.
