Quantitative Characterization Method of Internal Structures of Fault-Karst Reservoir Based on Division of Flow Units
摘要
Abstract
The characterization of fracture-cavity structure is crucial for the precise description of fault-controlled oil reservoirs.In the early stage,the characterization was carried out mainly through seismic geophysical method,and the correlation between this method and the development of dynamic data was not strong.Drawing on the concept of sandstone flow unit,by calculating the changes in flow coeffi-cient and storage volume,the division of flow units are carried out within the fracture-cavity unit and the fracture-cavity body,effectively highlighting the flow difference between different fracture-cavity structures.The quantitative characterization of fault-karst structure is a-chieved by transforming geological structure intoa numerical structure.The method was verified by applying it to modeling assignment and dynamic numerical simulation prediction of remaining oil.This method has good application effects and broad application prospects in improving oil recovery and increasing oil yield.关键词
