摘要：
The distribution of remaining oil and gas in reservoirs with gas cap and edge-bottom water is complicated after water injection, gas injection and degassing in oil ring. In view of the problems that only the saturation of remaining oil and gas cannot determine the change of the oil-water interface or oil-gas interface, and the influencing factors of remaining oil and gas are difficult to determine, we used the tracer simulation function of reservoir numerical simulation to label water injection wells, gas injection wells, water body area and gas cap area with different virtual tracers. Through the reservoir numerical simulation method, not only the influence of gas injection well and water injection well on remaining oil and gas can be determined, but also the sweep range of edge-bottom water and gas cap can be determined, so as to determine the changes of oil-water interface and oil-gas interface. This method deepens the understanding of remaining oil and gas potential.
