Reservoir heterogeneity; oil reservoir; heterogeneity characterization.Abstract
Reservoir heterogeneity is an important influencing factor that affects the development effect of oil and gas reservoirs and improves the recovery rate. In recent years, the research methods and techniques of reservoir heterogeneity have made remarkable progress. The definition and development status of reservoir heterogeneity are systematically elaborated through literature research, and it is believed that reservoir heterogeneity is mainly researched from the aspects of macro and micro heterogeneity at present. Combined with the current research hot spots, the paper focuses on the principles and application examples of field outcrop profiling, high-resolution sequence stratigraphy, non-homogeneous composite index method, reservoir flow unit method, experimental data analysis and Lorentz curves, and reservoir geologic modeling, etc., and summarizes the main factors affecting reservoir non-homogeneity. This paper aims to deepen the understanding of reservoir non-homogeneity research and further provide theoretical reference and technical support for oil and gas reservoir development.
