Abstract | 沉积层中水合物分解可能引起多种形式的地质灾害.针对水合物加热分解,尤其是快速加热条件下,可能引起的沉积层破坏方式及破坏条件进行了模型实验.模型实验分别在一个矩形模型箱中和一个圆柱形模型箱中进行,以模拟二维和一维情况.实验结果表明,随着水合物分解条件(如缓慢加热,快速加热)和水合物沉积层与覆盖层情况的变化(如地层非均匀,盖层可渗透和封闭等),沉积层在水合物分解后可能出现多种破坏方式,如滑塌缓慢破坏以及分层和喷发等强烈破坏,这些破坏均可对工程实践带来严重的危害,是水合物开发和深海油气田开采首要解决的问题之一 |
Other Abstract | Hydrate dissociation in marine deposits may cause large disasters.Experiments are carried out to study the failure conditions and modes caused by the dissociation of hydrate.A rectangular model box and a cylindrical model box are designed to simulate the two-dimensional and one-dimensional conditions respectively.It is shown that kinds of failure modes,including slowly sliding and settlement,layered destruction and burst,occur with the thermal dissociation of hydrate happened fast or slow and for different hydrate deposit and cover deposit(such as the heterogeneity of the deposit,permeability of the cover layer).Each kind of these failures is a severe threat to engineering. |
