Abstract: Xingliudong Block, having been developed for more than 40 years, finished its third infilling in 2007. Aiming at the problems of excessive layers, interlayer heterogeneity and great discrepancy of each layer’s producing extent, the waterflooding experiment of different permeability contrast combinations was carried out. Combining the adjustment research of layer series and well pattern, this reservoir is divided into three layer series which have a permeability contrast less than 6. Three corresponding well patterns are designed, which are significantfor the development of oil layers, especially the poor layers. With the numerical simulation technology, the best scheme is selected. According to the results, scheme 2, raising the oil recovery to 49.18%, is the best solution.

摘要: 杏北开发区杏六东区块于2 0 0 7年进行三次加密调整, 至今非主力层已水驱4 0余年。针对区块内油 层层数多、 纵向非均质严重、 各层动用程度相差大的问题, 开展了不同渗透率级差组合水驱油室内实验, 结合区块地 质特征进行了层系井网演变研究, 将每个层系渗透率级差控制在6以内, 把区块分为三个层系, 并针对不同层系设计 了相应的井网部署方案, 以此达到提高油层尤其是薄差层开发效果的目的。利用数值模拟技术优选所设计的井网 部署方案, 结果表明方案二将油藏最终采收率提高到了4 9. 1 8%, 为层系井网演变的最好方案。
