摘要

In recent years, the exploitation of shale gas in southwestern Sichuan, China, has increased significantly. But with the deepening of strata, the geological conditions become complex, and the mechanical properties of shale change with the increase of ground stress and geothermal. Creep is one of the important mechanical properties of rock, which affects the long-term stability of rock engineering. Therefore, this paper carried out triaxial creep test with the rock mechanics test system, and obtained the rock mechanics characteristics of shale under different conditions. The research results are of great significance for elucidating the creep deformation and failure characteristics of shale under high temperature and high ground stress conditions, and can provide important basic information for the exploration and development of shale gas reservoirs.
