Abstract:The distribution of remaining oil in the west of South-eight Block has been analyzed by using the method of numerical simulation according to dynamic and static data provided by the 2nd Oil Production Factory in Daqing oilfield.Three sets and 30 schemes of perforation adding about the timing of water injection,injection intensity,and orthogonal scheme have been designed aiming the tapping of remaining oil.The optimization results are:the best water injection intensity is 9,the best timing of water injection is 93%of water cut,and best orthogonal scheme is that when the water injection intensity is 9 and timing of water injection is 93%.
Keywords:Numerical simulation  secondary reservoirs  remaining oil  perforation
