GAS FRACTURING DEVICE FOR INCREASING PERMEABILITY OF ROCK, AND METHOD FOR EVALUATING INCREASE IN ROCK PERMEABILITY USING SAME

摘要

The present invention relates to a gas fracturing device using gas to increase the permeability of a rock, and a method for evaluating an increase in rock permeability using same and, more specifically, to a device which can gas-fracture a rock by using gas to increase the permeability of a rock, and a method for evaluating an increase in permeability using same, which are capable of precisely simulating actual in-situ stress and temperature conditions with respect to a cylindrical or hexahedron-shaped rock sample extracted from underground bedrock.
