Most of the domestic oilfields are developed by water flooding. The long-term erosion of injected water will transform the reservoir and change the physical properties of the reservoir. These changes continue to progress slowly, but the cumulative change range cannot be ignored. The reservoir physical property changes will affect the oil-water movement ability, and have a great impact on the oilfield development influence and the distribution of remaining oil in the later period. However, the mainstream commercial numerical simulation software at present fails to fully consider the time-varying phenomenon of reservoir physical property. According to the literature review, the numerical simulation methods considering the time-varying reservoir physical properties have some defects in continuity representation, directional representation and stability of calculation results. To solve this problem, it is necessary to establish a numerical simulation method based on the time-varying reservoir parameters. In this paper, a useful attempt is made to solve this problem, and an Eclipse-based time-varying simulation program is developed. Through the verification of various examples, all functions meet the design requirements and can realize time-varying simulation under different conditions.
