摘要
在分析海底天然气水合物赋藏区域地热场特征的基础上,借鉴盆地地热模型理论和方法,建立了海底天然气水合物赋藏区域的地热基本模型,并详细介绍了边界条件和导热系数的确定方法。由于天然气水合物的形成、分布与实际地质和地热条件密切相关,因此加强天然气水合物赋藏海域的地质与地热基础调查是构建准确可靠的地热模型的关键。
The analysis of the basic knowledge of geothermic field of natural gas hydrate reservoir regions in seafloor indicates that it is feasible to establish the basic geothermic field model of natural gas hydrate reservoir regions in seafloor following the theory and method of basin geothermic model. Then it discusses the method of confirming boundary conditions and coefficient of heat transfer in detail. Since the formation and distribution of natural gas hydrate is closely related to the geological and geothermic conditions, it is vital to intensify the basic survey of geological and geothermic conditions in those regions to establish an accurate and reliable model.
