生产测井资料在严重非均质油藏剩余油研究中的应用

Application of Production Log Data in Remaining Oil Study of Heterogeneous Reservoir

针对胡状集油田储层非均质性严重,储层纵向及平面渗透率变化大,难以准确建立地质模型,油藏数值摸拟准确率低的问题,根据水驱油动力学原理,把生产测井资料与流管法结合起来,利用生产测井资料提供的产液量和含水率及分层注入量等资料,确定油藏内任意一点上的剩余油饱和度及其分布,对油藏的开发调整和三次采油提供科学理论依据,为生产测井资料应用开辟了一个新领域。

This paper defines the remaining oil saturation and its distribution at any point of reservoir in view of the reservoir heterogeneity and longitudinal-plane permeability variation which causes to establish the geological model with difficulty or with lower accuracy of reservoir numerical modeling. It aslo points out that production log data should combine with the stream-tube method based on water oil displacement principle of dynamics, and use the fluid production and water cut date provided by production log data. This method provides the scientific theory basis for reservoir development adjustment and tertiary recovery, which opens a new field for production log data application.
