Abstract
A method, system and device for predicting an oil accumulation depth limit of deep and ultra-deep marine carbonate reservoirs is provided. The method includes: obtaining geological factors acting on a porosity of a deep/ultra-deep marine carbonate reservoir, standardizing absolute values of the geological factors; calculating a porosity of the deep/ultra-deep marine carbonate reservoir; acquiring ratios of oil, water and dry layers in each M % porosity interval, and acquiring a relationship between a dry layer ratio and the porosity of the deep/ultra-deep marine carbonate reservoir; recursively obtaining a relationship between the dry layer ratio and the burial depth and determining the oil accumulation depth limit of the deep/ultra-deep marine carbonate reservoir. The method, system and device solves the problem that the prior art cannot by predicting the oil accumulation depth limit directly through the relationship between the dry layer ratio and the depth.
