摘　　要：针对南堡凹陷高66X1断块沙河街组油藏的开发现状,通过精细地质研究成果,结合生产动态测试资料,分析影响油藏水驱效果的主要因素为受储层强非均质性影响,纵向上水驱储量动用程度偏低,平面上水驱波及方向单一,注水利用率低。根据剩余油分布特征提出了改善油藏水驱状况的调整对策,纵向上水井实施精细调配,平面上注采联动精细调整不同方向注采压差并配合合理储层改造措施,有效指导油藏高效开发。Aiming at Gao 66 X1 fault block in Nanpu sag shahejie reservoir development present situation, through the fine geologic research results, combined with dynamic production test data, analysis the main factors affecting reservoir water flooding effect is influenced by strong reservoir heterogeneity.The vertical water flooding reserves producing degree is low,flat water flooding affected direction, single water utilization rate is low.According to the characteristics of residual oil distribution, the adjustment countermeasures are put forward to improve the water flooding condition of the reservoir, such as fine allocation of vertical upper wells, fine adjustment of injection-production pressure difference in different directions by plane injection-production linkage, and coordination of reasonable reservoir transformation measures to effectively guide the efficient development of the reservoir.
