The Relationship between Oil Field Development and Pore Structure of Reservoir Rocks
Oil field development requires wide application of information on porestructure of reservoir rocks. This paper presents a method to compile a crosssection and isopleth map of pore structure, based on the theory of secondarymigration of hydrocarbons. This method can be used in research for oil-watercontact, identification of oil layer and water layer, trend of bottom waterconing and fingering during water flooding; and it can also be used to providethe basic map for establishing a 3-D model of pore structure in a reservoir.In addition, methods to determine the lower limit of reservoir rocks, relatedto calculations of reserves and methods in research for the relationship betweenpore structure and water-flooding recovery in oil field development, areintroduced. The article points out that pore structure data must be used withother geological information, though it is significant for the development of oilfields.
