葡南扶余油田注水开发实践表明:油层吸水能力差,注水压力高,注水开发效果差,采收率低;又由于该类油层中天然裂缝的普遍发育,加剧了油层平面的非均质性,给油田注水开发带来了许多因难,本文针对扶余油层开发中的主要矛盾,对注水开发问题进行了探讨,提出了适合扶余油层开发特点的注水调整对策,改善注水状况,优化水动力学驱油方法,为下一步开发扶余油层做好工作。
The practice of waterflooding in Funan Fuyu Oilfield shows that the reservoirs have poor water absorption capacity, high water injection pressure, poor water injection development results and low oil recovery. Due to the widespread development of natural fractures in these oil reservoirs, the heterogeneity of the oil layer is aggravated. In this paper, according to the main contradictions in the development of Fuyu oil layer, this paper discusses the problem of water injection development, puts forward the water injection adjustment measures that are suitable for the development of Fuyu oil layer, improves the water injection status, and optimizes the hydrodynamic drive Oil method, do a good job for the next step to develop Fuyu oil layer.
