坚韧+HYDRATE v1.0是一个新的水合物地质系统动态模拟程序。通过求解质量和热量平衡的耦合方程,坚韧+HYDRATE可以模拟常见天然CH{sub 4}水合物沉积物典型条件下的非等温气体释放、相行为和流体流动以及热量(即,在永久冻土和深海沉积物中),在任何尺度(从实验室到水库)的复杂地质介质中,达西定律是有效的。坚韧+HYDRATE v1.0包括水合物形成和分解的平衡和动力学模型。该模型考虑了热量和多达四个质量分量,即,水、CH{sub 4}、水合物和水溶性抑制剂如盐或醇。它们被分成四种可能的相(气相、液相、冰相和水合物相)。氢的解离或形成,相变和相应的热效应进行了充分的描述,因为是抑制剂的影响。该模型可以描述所有可能的水合物分解机制,即,降压、热刺激、盐析效应和通道诱导效应。坚韧+HYDRATE是坚韧+的第一个成员,是TOUGH 2的继任者[Pruess等人,1991]劳伦斯伯克利国家实验室开发的多组分、多相流体和热流的代码族。它是用标准的FORTRAN 95编写的,可以在任何有这种编译器的计算平台(工作站、PC、Macintosh)上运行。
TOUGH+HYDRATE v1.0 is a new code for the simulation of the behavior of hydrate-bearing geologic systems. By solving the coupled equations of mass and heat balance, TOUGH+HYDRATE can model the non-isothermal gas release, phase behavior and flow of fluids and heat under conditions typical of common natural CH{sub 4}-hydrate deposits (i.e., in the permafrost and in deep ocean sediments) in complex geological media at any scale (from laboratory to reservoir) at which Darcy's law is valid. TOUGH+HYDRATE v1.0 includes both an equilibrium and a kinetic model of hydrate formation and dissociation. The model accounts for heat and up to four mass components, i.e., water, CH{sub 4}, hydrate, and water-soluble inhibitors such as salts or alcohols. These are partitioned among four possible phases (gas phase, liquid phase, ice phase and hydrate phase). Hydrate dissociation or formation, phase changes and the corresponding thermal effects are fully described, as are the effects of inhibitors. The model can describe all possible hydrate dissociation mechanisms, i.e., depressurization, thermal stimulation, salting-out effects and inhibitor-induced effects. TOUGH+HYDRATE is the first member of TOUGH+, the successor to the TOUGH2 [Pruess et al., 1991] family of codes for multi-component, multiphase fluid and heat flow developed at the Lawrence Berkeley National Laboratory. It is written in standard FORTRAN 95, and can be run on any computational platform (workstation, PC, Macintosh) for which such compilers are available.
