The invention relates to a shale reservoir determination method and device, computer equipment and a storage medium, and relates to the technical field of petrochemical engineering. The method comprises the following steps: determining shale lithofacies of at least two shale samples; the at least two shale samples are shale core samples; obtaining experimental test results of the at least two shale samples based on a nitrogen adsorption method and a high-pressure mercury injection method; based on an experimental test result, obtaining a high-quality pore structure combination; based on the high-quality pore structure combination, screening the at least two shale samples to obtain a target shale sample; and determining the shale lithofacies with the highest lithofacies distribution frequency in the target shale sample as the high-quality shale oil reservoir. By means of the method, the problem that a macroscopic reservoir is difficult to guarantee in a microscopic experiment in determination of the mud shale
