原始语种摘要: Oil shale has a very important strategic value for energy safety, but in situ pyrolysis technology still faces both scientific and technical problems that urgently need to be overcome. Among the current world’s oil shale in situ conversion technologies, the Chinese in situ pyrolysis technique, which consists in injecting high-temperature water vapor, is considered to be one of the most efficient methods in this field. The thermal-hydraulic-mechanical-chemical (THMC) coupling model for this method is presented. Based on the model, the temperature distribution and permeability evolution were simulated. It was concluded that, first, due to the existence of prefracturing cracks, the pyrolysis front tended to be focused on both sides of the prefracturing cracks and the region had a relatively...
