Abstract
A method and device for obtaining microscopic occurrence characteristics of oil stored in a shale, where the microscopic occurrence characteristics include the adsorbed oil film thicknesses in the shale and the oil distribution in the shale. The method includes four steps. The first step is an experiment step in which a N-Hexane vapor adsorption experiment is performed on a sample made from a shale. The second step is a first obtaining step for calculating and obtaining the adsorbed oil film thicknesses in the shale. The third step is a first calculating step and the fourth step is a second obtaining step. They aim to obtain the oil distribution in the shale.
