| [摘 要]在目前已有的主要水合物开采方法研究的基础上,进一步研究了天然气水合物加热开采法的机理。研究认为,水合物是加热分解、热传导和含化学分解的液、气两相渗流流动,它们之间既相互独立,又相互联系。并将水合物区划分为分解区和未分解区,将分解区前缘作为可移动的分界面,分区建立了加热分解热传导数学模型及含分解化学反应的液、气两相渗流流动数学模型,为加热开采水合物气层过程进行深入研究奠定了基础。 |

| Abstract:Based on current existing methods of hydrate exploitation,this paper further studies the mechanism of the hydrate heating exploitation method. It is considered that the hydrate is the result of heating decomposition,heating transfer and two-phase seepage flow of fluid and gas with chemical decomposition,which are not only mutually independent but also interconnected. Hydrate areas are divided into decomposition and non-decomposition areas.
The front edge of the decomposition area is used as a mobile interface. Mathematical models of heating decomposition,heating transfer and two phase seepage flow of fluid and gas with chemical decomposition in decomposition area were established,which lays a foundation for further study of the hydrate heating exploitation process. |
