Overview of Research Methods of Microscopic Pore Structure with Material Properties in Reservoir Rocks

Article Preview

Abstract:

Pore reflects fluid storage capacity of the rock, while the shape and size of the throat, together with the pore throat ratio, control the permeability and fluid reservoir capacity. There are mainly two aspects in microscopic pore structure characteristics evaluation at present: experiment and theoretical modeling. In this paper, several experimental methods and modeling methods that currently exist were compared and analyzed. The analysis shows that in the aspect of experiments, the domestic basic research in the field of three-dimensional pore structure model reconstruction technique is still relatively weak under limited conditions of equipment and technology, while in the aspect of models, the current domestic research is still relatively rare. A conclusion is drawn that the main problems in the study of microscopic pore structure at home are still the degree of improvement in the accuracy of the experiment and the model upgrade.
