The present paper gives a detailed description of interstratal, intrastratal and planar heterogeneity and its main influencing factors in the fluvial reservoirs of the 34 reservoirs in the 2nd member of the Shahejie Formation in the 2nd district of the Shengtuo oil field in the light of reservoir architectures and logging interpretation by using the entropy’s method. The 34 reservoirs are turned out to be moderate to highly nonhomogeneous, and become progressively higher with the increase of water injection. The planar heterogeneity tends to be higher than the interstratal and intrastratal ones. The reservoir heterogeneity is believed to be controlled by reservoir architectures, and more complicated by diagenesis.
