Abstract
Oil reservoir numerical simulation technology is one research approach of stratum geology as well as oil reservoir development by applying mathematical methods, which establishes the simulation model of stratum oil reservoir through the oil reservoir geology model, permeability mathematical equation and numerical model. In this study, we want to seek for the oil-water distribution law as well as its characteristics in X block geology of an oil field by using the STARS model. In addition, the development history of the geology of this oil field was simulated and the development potential of this block was discussed. The results indicated that the geological model of 13 wells was extracted, which were divided into 7 simulation layer vertically with the grid system of 23×9×7 = 1449. According to the single well fitting, among the 9 producing wells in the testing well block, six wells achieved good fitting, occupying 66.67%, while the rest three wells achieved poor fitting, occupying 33.33%. The prediction result that on Oct., 2026, the recovery percentage of X block was 40.95%, the oil produced was 11.09×104 t and the residual geological reserves were 15.99×104 t.
