Abstract: One of the means for accurately predicting remaining oil distribution is the numerical simulation of reservoir based on the fine description of the reservoir. The structure of faulted layered reservoir is more complex, and fault ridge has shielding action to the seepage flow of reservoir fluids. A processing method for correctly establishing the structural model of the reservoir and describing the permeability of the fault ridge is put forward in this paper, which is one of the two keys to the numerical simulation of the faulted layered reservoir; the other key is the fitting of reservoir production history. The idea is put forward that the production history of fault block is firstly fitted, and then the performance of individual well is fitted. This method is applied to the numerical simulation of remaining oil distribution of the faulted layered reservoir in western Wen-25 zone, which has been developed for more than 20 years.
