摘　　要：针对高含水期油藏剩余油分布特征,以油藏工程理论为基础,考虑经济因素,建立了特高含水期油藏剩余可采储量丰度分区划分方法,得到了整个油藏的高潜力区域与低潜力区域。结合油藏渗流状况划分出了油藏的高速流动区域与低速流动区域。综合考虑2种分区结果,进一步确定了不同区域的开发对策。在实际区块的应用结果表明,综合考虑油藏的高潜力区域与低潜力区域和地层渗流的低速流动区域与高速流动区域,可以与开发对策进行有效耦合,对特高含水期油藏调整开发对策具有实际指导意义。Aiming at the distribution characteristics of remaining oil in high water cut reservoirs, based on the theory of reservoir engineering and considering economic factors, a partitioning method for the abundance of remaining recoverable reserves in ultra high water cut reservoirs was established and the high-potential and low-potential area of the whole reservoir were obtained. The high-speed and low-speed flow area of the oil reservoir were divided according to the reservoir seepage conditions. Comprehensive consideration of the two zoning results further determined the development strategies for different regions. The application results in actual blocks show that comprehensive consideration of the high-potential and low-potential area of the reservoir as well as the low-speed and high-speed flow area of formation seepage can be effectively coupled with development strategies, which is useful for adjusting and developing strategies for ultra high water cut reservoirs.
