摘　　要：D油藏属于深水油藏,平面上存在严重的非均质性,导致开发过程中注采不均衡,同一井网中生产井见水的时间也存在很大的差异,这些都会导致非均质油藏出现最终采收率低的问题。根据矢量井网井距的理论公式,依据相似准则建立了D油藏平板模型。应用数值模拟方法将优化井网与现有井网进行对比分析,结果证明了矢量井网可以大大提高该油藏平面上的波及系数,提高驱油效率。D reservoir is a serious heterogeneity planes deepwater reservoir, the development process is not balanced, there is a big difference in the same network production wells of the water breakthrough time,all this will lead the low ultimate recovery of heterogeneous reservoirs.Based on the theoretical formula of vector well pattern and similar criteria,a flat D reservoir model was established.Comparison and analysis were carried out between optimized vector well pattern and the original one by using numerical simulation method. The results have proved that,the vector well pattern can greatly improve the reservoir sweep efficiency and displacement efficiency.
