【Abstract】 By using the two layer geological model that reflects the strata heterogeneity,this paper presents an analysis solution to the cycle flooding of stratified sandstone reservoir.Then studied the dynamic parameters(e.g.surge range and surge frequency)which have effect on cycle flooding.The result shows that the maximum of the surge range if possible should be reached and the value of the relative surge frequency should be equaled to two in order to get the best development effect in practical of cycle flooding.Therefore,the optimum parameters should be selected to carry on cycle flooding in stratified sandstone reservoir.更多还原
