Abstract
A method for correcting a movable hydrocarbon content of high gas-oil ratio shale oil based on phase behavior and rock pyrolysis includes: S1, simulating and preparing a fluid under original formation conditions based on formation fluid properties of a target block; S2, performing a pressure-volume-temperature (PVT) experiment and a fluid property test on the fluid prepared in the step S1 to obtain a composition of well fluid and a deviation factor; S3, establishing a theoretical shale movable hydrocarbon content prediction model to calculate a shale theoretical movable hydrocarbon content and a light hydrocarbon correction factor, and S4, determining, based on the light hydrocarbon correction factor obtained in the step S3, a restored light hydrocarbon content of shale oil and a restored original total oil content. This method, considering geological conditions and fluid properties of various shale oil reservoirs, corrects the movable hydrocarbon content of high gas-oil ratio shale oil.
