摘要：In the carbonate oil field offshore of Sumatra block in Sunda basin, RQI (Rock Quality Index) and FZI (Flow Zone Index) have proved to be effective method of dividing the flow units. The method utilizes the porosity and permeability of the core rock samples to divide the flow units of the K oil field carbonate reservoirs. The field consists of six flow units, and they represent different flow characteristics. The results show that each flow unit has a specific relationship of porosity and permeability and a specific capillary pressure curve (J function); this feature is related to the rock pore structure and pore size. In the application, the flow unit model is built by a stochastic modeling method, and the permeability model and the oil saturation model are built under the control of the flow unit model.
