摘　　要：明一西油藏是文明寨油田主力油藏之一,目前综合含水90.47%,采出程度45.72%,已进入高含水、高采出阶段,由于构造复杂、井况损坏严重等问题造成剩余油挖潜难度不断加大。通过密集井网开发区低序级断层精细解释微构造,以地震属性为主的单砂体地震定量描述,有效落实了10m级别的井间断层展布、定量描述了最大厚度5m以上的单砂体井间变化,为复杂断块油藏的开发提供有力支撑;根据剩余油分布特征,制定适合高含水期挖潜配套技术,实现了明一西油藏高效开发。Mingyixi reservoir is one of the main reservoirs in wenmingzhai oilfield. At present,the comprehensive water cut is 90.47% and the recovery degree is 45.72%. It has entered the stage of high water cut and high production.Through the fine interpretation of micro-structures by low-order faults in the dense well pattern development zone and the quantitative description of single sand body earthquakes with seismic attributes,the inter-well fault distribution of 10 m and the inter-well changes of single sand body with the maximum thickness of more than 5 m are effectively implemented,providing strong support for the development of complex fault block reservoirs.According to the distribution characteristics of remaining oil,the development of supporting technologies suitable for high water-cut period was carried out,and the efficient development of mingyixi reservoir was realized.
