Abstract: The vertical and horizontal heterogeneity of the reservoir in Bohai Q oilfield is strong, so it is difficult to accurately establish the geological model, and there is a problem of low fitting accuracy in the history of reservoir numerical simulation in ultra⁃high water cut period. Based on the theory of percolation mechanics, production logging data and streamline simulation are combined. The combination of the pipe method and the use of production log data to provide the amount of liquid production and water content and stratified injection amount to determine the residual oil saturation and its distribution at any point in the reservoir. By using this method, the measures of flow field regulation of water injection unit and water blockage of local well group are proposed. The output of oil wells is increased by 14 times, and the annual oil production of oilfield is negatively decreasing. The practice shows that the combination of production logging data and streamline simulation can effectively identify the remaining oil distribution, and provide scientific theoretical basis for the development and adjustment of highly heterogeneous reservoirs in ultra⁃high water cut stage.

摘要： 　渤海Q油田储层纵向及平面非均质性强，地质模型建立难度大，且存在特高含水期油藏数值模拟历史拟合准确率低的问题。基于渗流力学理论，生产测井资料与流线模拟相结合，利用生产测井资料提供的单层产液量和含水率及分层注入量等数据，判断流体运移规律，确定油藏内任意一点上的剩余油饱和度及其分布。应用该方法，渤海Q油田进行注水单元流场调控，提出增注、卡层、堵水等措施，单井产量增加14倍，油田年产油量负递减。实践表明，生产测井资料与流线模拟结合可有效识别剩余油分布，为特高含水期强非均质油藏的开发调整提供科学理论依据。
