摘要:
通过对岩石矿物、储层物性、油层敏感性和水驱油效果分析,在储层地质研究基础上,评价青平川油田 长2油藏注水开发效果。研究结果表明,长2油藏含油砂岩以细粒长石砂岩为主,粘土矿物中绿泥石含量较高。 储层物性差,属于典型的低渗透岩性油藏。水驱油实验结果表明,青平川油田长2油层水驱油效果较好,油田最 终驱油效率可达49.4%。先导性注水试验表明,注水开发可以使青平川油田产量在较短时间内得到大幅度提 高,在注水后的第4到第7个月达到产量高峰期,第8个月后进入稳产期。油田注水开发产量递减规律分析表 明初始递减律为0.0191(1/月)。根据青平川长2油藏实际情况,认为注水开发能达到提高采油速度和油田最 终采收率的目的。
Abstract:
Chang 2 reservoir of Qingpingchuan oil field, located in the eastern Shanbei slope of the Erdos Basin, is a typical low penetrability oil reservoir. Fine-grained feldspar sandstone is the main oil-bearing rock and chlorite is the dominant kind of clay minerals. Physical property is not nice for oil production because of low porosity and penetrability, however experiment of water injection shows that it has high water injection efficiency which is up to 49.4%. Results show that water injection can largely increase oil production in a short time stage. The peak production can be reached at the 4th to the 7th months after water injection, and the production would decrease after the 8th month. The initial production decrease degree of water injection is 0.019 1(1 /month). It indicates that water injection can increase both of oil production speed and oil recovery.
