Abstract

A simulation analysis method for an injection volume of alternate displacement of shale oil by carbon dioxide and nitrogen includes steps of simulating the alternate displacement of shale oil by carbon dioxide and nitrogen for multiple times through the core displacement simulation experiment, measuring the oil displacement efficiency change for every time, obtaining the porosity change in the entire displacement process through the porosity change before and after alternate displacement, and building the injection volume adjustment expression of alternate displacement of shale oil by carbon dioxide and nitrogen as a reference of the injection volume of alternate displacement of shale oil by carbon dioxide and nitrogen, so that the total displacement efficiency in the actual mining process is improved, thus increasing the production rate of shale oil and reducing the usage amount of carbon dioxide. A simulation analysis device is used to carry out the simulation analysis method.
