注水开发是对油藏补充能量的重要措施,是油田提高采收率的有效手段。因此,对于注水导致油井水淹问题,有必要开展专项研究。在对油藏精细描述、测试资料分析和生产动态研究基础上,准确判断出水层及剩余油分布规律。通过采取对油层平面、层间和层内调整改造,尽可能地使水淹井恢复生产,以提高油井利用率,并使未被水淹的油井得到进一步的稳油控水,提高油田水驱效率和最终采收率。开展水淹井综合治理技术研究,旨在探索出一条油田预防水淹、治理水淹的新思路和新方法,使油田注水开发产能建设上,以较小的投资成本,获取较大的经济效益。
Waterflooding is an important measure to replenish the reservoir and is an effective means to enhance oil recovery. Therefore, it is necessary to carry out special research on water flooding caused by flooding. Based on the detailed description of the reservoir, the analysis of the test data and the production dynamics, the distribution rules of the water layer and remaining oil are accurately judged. Through the adjustment of the reservoir plane, interlayer and strata, the flooding wells can be restored to production as much as possible so as to improve the utilization ratio of the wells and to further stabilize the oil and improve the water flooding of the flooded wells Efficiency and ultimate recovery. To carry out research on comprehensive treatment technology of water flooding wells aims to explore a new idea and a new method for preventing flooding and water flooding in oilfields so as to make greater economic benefits in the construction of oilfield waterflood development and production capacity with less investment cost .
