Abstract：This paper presents the principle and method of the depositional process-based reservoir stochastic modeling.Compared with conventional stochastic modeling methods，the depositional process-based method，which efficiently integrates empirical observation and expert knowledge with respect to depositional process，enables the geologically realistic reproduction of reservoir architectural elements(such as channel fill，lateral accretion，levee，and crevasse splay)geometries and interrelationship，as well as how they are deposited over time（such as avulsion and meandering fluvial migration）.As to well conditioning，a new conditional method is adopted to improve the efficiency，while retain complicated geometries and interrelationships.Through theory and experimental results analyses，the depositional process-based reservoir stochastic modeling integrates more geological information，can represent reservoir heterogeneity more precisely.Finally，some present problems and future work are discussed such as the generation of channel centerlines，the representation of lateral accretion shale beddings in point bar，and well conditioning.
