NUMERICAL SIMULATION FOR HEAT-SOLID COUPLING OF COAL UNDER INJECTING HEAT

摘要：

Based on the mechanism for heat-solid coupling of coal under injecting heat,the numerical model for heat-solid coupling of coal under injecting heat has been established.The temperature field and stress field laws of coal body nearby the well casing with exploitation are found.The results show that the temperature of coal nearby the well is higher than it far away the well.The heat action on the boundary spread to interior of coal gradually along with time.The velocity of gas desorption increase tremendously because of augmenting of temperature gradient,and the gas will release hand over fist from matrix of coal and the surface of coal body.The reservoir stress extends from well to surrounding rock along with time.The simulation results could provide reference on heat-solid coupling of coal under injecting heat.
