中文摘要：
层重新聚集是在高水切割舞台根据物理性质和层的恢复百分比把所有层划分成生产系列的几个集合，它是一种重要技术为高水切割 multilayered 水库改进油恢复。不同重新聚集情形可以导致不同生产表演。基于不稳定的油水流动理论，一个多层的混合水库模拟器被修改生产裂口方法建立。考虑层性质的差别，包括渗透，油粘性，和留下的油浸透，假流动抵抗对比被建议用作层为高水切割 multilayered 水库重新聚集的一个典型索引。有不同假流动电阻的 multilayered 水库的生产索引与数据从 Shengtuo 油矿在被带的确定的模型一起被预言。当重新聚集的层被实现时，模拟结果证明假流动抵抗对比应该是不到 4。聚类方法的 K 工具，基于客观函数，被用来自动地执行重新聚集的层进程根据假流动电阻。研究结果在 Shengtuo 油矿被用于 Shahejie 形成的第二个成员的 IV-VI 沙组，有利发展表演被获得，并且油恢复被 6.08 % 提高。
英文摘要：
Layer regrouping is to divide all the layers into several sets of production series according to the physical properties and recovery percent of layers at high water-cut stage, which is an important technique to improve oil recovery for high water-cut multilayered reservoirs. Dif- ferent regroup scenarios may lead to different production performances. Based on unstable oil-water flow theory, a multilayer commingled reservoir simulator is established by modifying the production split method. Taking into account the differences of layer properties, including per- meability, oil viscosity, and remaining oil saturation, the pseudo flow resistance contrast is proposed to serve as a characteristic index of layer regrouping for high water-cut multilayered reservoirs. The production indices of multi- layered reservoirs with different pseudo flow resistances are predicted with the established model in which the data are taken from the Shengtuo Oilfield. Simulation results show that the pseudo flow resistance contrast should be less than 4 when the layer regrouping is implemented. The K-means clustering method, which is based on the objec- tive function, is used to automatically carry out the layer regrouping process according to pseudo flow resistances. The research result is applied to the IV-VI sand groups of the second member of the Shahejie Formation in the Shengtuo Oilfield, a favorable development performance is obtained, and the oil recovery is enhanced by 6.08 %.
