Reservoir Heterogeneity

Abstract

Description and characterization of reservoirs, a direct target stratum for petroleum exploration and development, are at the center of petroleum reservoir research, whose core lies in the research on reservoir heterogeneity. This is because heterogeneity in reservoir characteristics is closely related to oil and gas reserves, stored energy, yield, and productivity. The first technical problem to be solved is accurately recognizing the various characteristics of petroleum reservoirs during their development. Only through scientific, systematic, and quantitative studies of the heterogeneous characteristics of reservoirs, the benefits of petroleum exploration and development can be improved, the position of development wells selected optimally, and a scheme for improving the hydrocarbon recovery ratio be designed reasonably.
