CMG-STARS (Computer Modelling Group-Advanced Processes & Thermal Reservoir Simulator) was chosen to simulate the process of thermally-induced hydrate dissociation owing to its robust reaction kinetics and geomechanics tool and its feasibility has been validated by many researchers. A 2D symmetric cylindrical numerical simulation model was developed. A vertical well was centrally positioned in the model and was used to simulate thermally-stimulated hydrate decomposes. The mesh division of the

摘要：

Natural Gas Hydrate (NGH) is characterized by large reserves and cleanliness, which has attracted wide attention around the world. Thermal stimulation is considered to be one of the possible methods to facilitate hydrate dissociation. In this paper, the hydrate is dissociated through injecting hot water. In order to reveal the influence of the speed and the temperature of injected hot water on the temperature distribution, hydrate dissociation front, gas production rate, and cumulative gas production, a 2D cylindrical mathematical model of thermally-induced hydrate dissociation was established...
