Zusammenfassung: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. La présente invention concerne un dispositif de fracturation utilisant un gaz pour augmenter la perméabilité d'une roche, et un procédé d'évaluation d'une augmentation de la perméabilité de la roche l'utilisant et, plus spécifiquement, un dispositif qui peut fracturer au gaz une roche en utilisant un gaz pour augmenter la perméabilité d'une roche, et un procédé d'évaluation d'une augmentation de la perméabilité l'utilisant, qui permettent de simuler avec précision des conditions de contrainte et de température réelles in situ par rapport à un échantillon de roche cylindrique ou hexaédrique extrait du substratum rocheux souterrain. 본 발명은 암석의 투과도 증진을 위해 가스를 이용한 가스파쇄 장치 및 이를 이용한 암석 투과도 증진 평가 방법에 관한 것으로서, 더욱 상세하게는 지하 암반에서 채취한 원통형 혹은 육면체형상의 암석 시편에 대하여 실제 현장(In-situ) 응력 및 온도 조건의 정밀 모사가 가능하며 암석의 투과도 증진을 위해 가스를 이용하여 암석의 가스파쇄가 가능한 장치 및 이를 이용한 투과도 증진 평가 방법에 관한 것이다.
