| 摘 要： | 文章通过对天然气水合物资源及其赋存区典型地貌体特征的分析,梳理了天然气水合物赋存区和麻坑地貌体的地质灾害类型,阐述了由于天然气水合物分解释放造成海底滑坡、滑塌和甲烷气体大规模逸散,继而引起海底输电或通信电缆毁坏、海洋石油钻井平台垮塌,甚至海啸和全球气候变暖等严重灾害。为天然气水合物勘探和开采提供有益参考。

| Abstract: | Based on the analysis of natural gas hydrate resources and the typical geomorphology features of their occurrences,the paper combed the geological disasters of natural gas hydrate occurrences and pockmark geomorphology.The effects were introduced including natural gas hydrate decomposition and release on submarine landslides,collapse and large-scale escape of methane gas which in turn led to the destruction of submarine transmission or communication cables,offshore oil rig collapse,and even tsunamis and global warming and other serious disasters.A scientific basis for gas hydrate exploration and exploitation was also provided. |
