Part 1 [6] presented an algorithm for modeling the process of pyrolysis of a hybrid system, including kerogen, tar-asphalt compounds and light oil, in the presence of hydrocarbon solvents. In addition, the previous article discussed the first stage of building a hydrodynamic model (HDM), namely, the choice of the physical modeling results in autoclaves and pyrolytic studies for debugging the model.

The present article considers the second stage of a HDM building for the process of kerogen conversion under the exposure to hydrocarbon solvents and temperature based on a set of laboratory core tests, namely, the process of creating a HDM in the CMG STARS software is described. The article also presents the dependence of the degree of involvement of the non-drained part of the section in the development on temperature, which is taken into account at the third stage of modeling. Within the framework of the described approach, a model of chemical transformations (MCT) during heating of the drained and non-drained parts of the Upper Jurassic section is presented with a description of the selected pseudo-components and kinetic parameters.

The developed model will allow in future to calculate the heating of the Upper Jurassic deposits, which results in the extraction of generated synthetic oil by hydrocarbon solvents as well as to consider various heating strategies and well configurations to select the most effective development method.
