Research on Material of Solid Gas Coupling Similar Simulation

Based on the research of single-phase similar model materials, choosing paraffin, sand and oil as the aggregate and cementing agent to make triaxial test by a certain percentage, the research tests the compressive strength and it's permeability, and then comes out the ratio range which is similar to original rock compressive strength and permeability. Results show that with the continuous increase of the proportion of paraffin and sand, the compressive strength of materials increases; while test changes the amount of oil, the inflection point which caused the decrease of compressive strength keeps moving backward, this eliminates the weakness of compressive strength change of materials when the test simply uses paraffin and sand. The permeability of material is controlled by adjusting the ratio of paraffin and sand.
