The reservoirs of Chang 4+5 and Chang 6 members in Hejiaji area are characterized by thick sand body, fine grain, faster change of sedimentary facies, and reservoir physical property has obvious heterogeneity in both the vertical and horizontal direction. Further research shows that reservoir factors that affect oil accumulation include petrological component, sedimentary facies, sand body distribution, diagenesis and physical property, etc., among which sedimentary facies is the most important one. Distributary channel sand bodies in deltaic plain are the main reservoirs. It is suggested that the next exploration should be in distributary channel sand bodies.
