Abstract: Taking fluvial and deltaic reservoir in Shengli Oilfield as an example and applying the multi-subject theory and many methods such as core rock analysis,log evaluation,physical simulation and numerical simulation on reservoirs,the characters and rules of variation of macro parameters for the reservoirs in the process of water flooding development in continental faulted basin were investigated.The mathematical model and predictable model for calculating macro parameters of reservoir flow field in special high water cut development stage were built up.The variation mechanism of macro parameters for reservoir flow field in the period of water flooding development was discussed.The research result shows that the development liquid has a great effect on permeability of reservoir while it has no effect on the porosity of reservoir.The dynamic geological process is the main factor resulting in the change of macro parameters of reservoir.
