摘　　要：双河油田437块经过近23年的开发,目前含水已高达96％。从高含水期油藏的渗流特点出发,充分利用试井技术能求取地层径向渗流参数的特点,结合油藏工程学有关原理,从含油饱和度研究入手,对剩余油饱和度分布特征进行了深入研究,搞清了437块剩余油饱和度的分布情况,获得了对于特高含水期油田剩余油分布的规律性的认识,对老油田调整挖潜和三次采油具有重要的指导意义。Current water cut is up to 96% in the Block 437 in Shuanghe oilfield, which has been on production for 23 years. This paper studies on the characteristics of seepage flow in reservoirs at high water cut development stage. The features of radial seepage flow parameters are established by using well test technologies. The distribution characteristics of residual oil saturation are studied in detail on the basis of oil saturation and with reservoir engineering principles. The distribution of residual oil saturation in the Block 437 is determined and the pattern of residual oil distribution at super high water cut stage is understood. They have important guiding significances to production plan adjustment and tertiary recovery in oil oilfield.
