Reservoir Modeling and Numerical Simulation Controlled by Flow Units

Abstract:

Geological model controlled by sedimentary microfacies can not able to accurately reflect the actual seepage characteristic, How to apply the static flow units to the dynamic reservoir numerical simulation is the advancing edge of petroleum industry. The method of reservoir geological modeling controlled by flow units is proposed. Firstly, the 3D models of flow unit should be build, secondly, the 3D porosity and permeability model are established controlled by the model of flow unit, thirdly, the 3D fluids saturation model is calculated by Leverett J function based on porosity and permeability mode. Selecting different relative permeability curves according to different flow units in history matching. which realizes the dynamic (development geological) and static (reservoir engineering) combination. The oilfield examples shown that the velocity and precision of history matching can be significantly improved by using the method mentioned. Flow units were proposed by Hearn in 1984^[. Study on flow units, which could not only deepen the understanding of reservoir geology, make reservoir evaluation more reasonable and reduce the heterogeneity impact on oil development, but also could be of great significance to improve oil field development effect especially for tertiary oil recovery^[. Previous studies mainly focused on defining the concept of flow units, divide method of flow units and so on, but few studies on how to apply the study results of static flow units to the dynamic reservoir engineering and reservoir simulation^[3-. Our research aimed at how to connect the static flow units and the dynamic reservoir simulation closely so as to achieve "dynamic and static combination".
