摘要
目前PB油田已进入高含水开发阶段,属三角洲前缘亚相沉积,其水下分流河道内部储层非均质性是影响注入剂驱油效率高低的关键地质因素。应用地质、测井等资料,分析了一个典型多期次水下分流河道的内部储层模式及沉积结构特征,建立了该河道内部三维地质模型,一定程度上反映了河道内部储层及非均质性情况,对该类储层剩余油挖潜具有指导意义。
The PB Oilfield was at high water cut stage,and reservoir rocks were mainly composed of the delta front sandbodies.The heterogeneity of internal reservoir of the underwater distributary channel was a key geological factor influencing the displacement efficiency of injectant.The pattern and sedimentary architecture of internal reservoir were analyzed for a typical multi-cycle underwater distributary channel based on geological setting and well logging data.The 3D geological model of the internal reservoir is established to reflect the distribution of internal reservoir and heterogeneity to a certain extent.This indicated that 3D Geological Model is significant for tapping the potential of residual oil.
