天然气水合物数值模拟方法及其应用
Numerical Simulation Methods and their Application to Natural Gas Hydrate Exploration
摘要
Abstract
Before dril ing for natural gas hydrate (NGH), it is necessary to use a numerical simulation method to study its formation and/or decomposition, and to identify a suitable scheme for its exploration. According to both field and laboratory experimental data, numerical simulations can be used to quantitatively calculate the dynamic transformation relationships among pressure, temperature, and NGH, and to evaluate the potential for NGH production by predicting the thermal physical dynamic processes involved in its occurrence. The TOUGH+HYDRATE software is used to simulate the decomposition process of NGH with respect to multicomponent and multiphase flow. The basic principles and methods used in the software are described, and an example is given of the application of simulations using the software, including depressurization, thermal stimulation, and the combination of both. The paper discusses current research and numerical simulation work being conducted with regard to investigations of NGH in China.关键词
