| 摘 要： | 把沉积学与储层物性相结合,从流动单元体系的角度出发,提出了流动单元划分的新方案.在流动单元体系内部划分出流动单元、亚流动单元和渗流区3个不同层次.在储层精细小层对比的基础上,首先根据区域内连续分布的隔层把储层分成几个独立的流体压力系统,即流动单元;然后再根据不连续分布的隔层,把一个流动单元进一步分成若干个亚流动单元;最后根据储层物性的差别把流动单元/亚流动单元划分成不同的渗流区.按照这个思路,选取临南油田的典型高产区块———以三角洲前缘亚相沉积为主的夏52块砂三中段三砂组,进行了流动单元、亚流动单元和渗流区的划分,共划分出7个流动单元、7个亚流动单元和63个渗流区,这样划分出来的流动单元体系同时包括了油藏整体与局部细节的特征,为油藏开发提供了详细的地质依据,也在实际应用中取得了良好的效果.

| Abstract: | A new method for flow unit division is proposed which combines sedimentology and the physical properties of a reservoir. The flow unit system is sub-divided into three hierarchies: flow unit, sub-flow unit and seepage zone. On the basis of elaborate sandbody correlation and according to the continuously distributed insulating layers, the reservoir is divided into several individual fluid-pressure systems, namely, flow units. A flow unit is divided into several sub-flow units according to the discontinuously distributed insulating layers. Finally, a sub-flow unit or flow unit is divided into several seepage zones according to the physical properties of the reservoir. A typical prolific block in Linnan oilfield, Xia 52, was selected for this study. According to the dividing method, Xia 52 was divided into 7 flow units, 7 sub-flow units and 63 seepage zones. Such fluid unit system, which includes both frame and local detail characteristics of the reservoir, provides detail geological information for reservoir development. Good effect has been achieved by applying such method in Linnan oilfield. |
