Abstract: The physical simulative experiment and core analysis of contrast wells in different development stage were used to illustrate different type of reservoirs in continental faulted basin.The variable features of parameters in the different development stage of microcosmic reservoir were investigated,and the evolvement mechanism of microcosmic reservoir was revealed.The parameters in flow field of microcosmic reservoirs with different origin developed in continental faulted basin changed regularly with increment of water cut in oil field.The propping manner of granule in microcosmic skeleton field turned from close type into the unconsolidated one.The content of clay mineral and small particle in strata was reduced gradually and enriched in local area.The heterogeneity of microcosmic pore throat network field was enhanced.The parameters for controlling the ability of fluid flowing in seepage field were better.The lipophilicity of reservoir rock was weakened.The changing mechanism of lipophilicity of reservoir rock was unchangeable.
