摘要
北极海域赋存丰富的油气和天然气水合物资源,也是全球环境变化的一个重要窗口,北极巴伦支海西南部陆架已发现大量天然气水合物赋存的识别标志,笔者综述了巴伦支海西南部海域陆架区水合物形成的条件和已发现的天然气水合物分布情况和泄漏特征,总结影响巴伦支海西南陆架区天然气水合物形成和分解的各项因素,评价北极巴伦支海西南部天然气水合物资源前景。掌握北极巴伦支海及其周边区域的水合物资源情况是提升中国在北极事务话语权的必要内容之一,北极海域水合物动态变化对于全球气候变化具有十分重要的指导意义;这类极地低温海域水合物流体聚集和运移特征十分特殊,对丰富水合物成藏研究有重要的理论意义。
There are abundant petroleum and gas hydrate resources in the Arctic,which is also an important window to the study of global environmental change.A large number of methane leakage activities have been found in the southwest Barents Sea.This contribution is devoted to a review of published literatures from previous investigations,so as to sum up the resource indicators,leakage characteristics and spatial distribution of gas hydrate found on the continental shelf of the southwest Barents Sea,reveal the controlling factors of gas hydrate formation and decomposition and evaluate the resource potential of gas hydrate.It is important to ascertain the hydrate resources in and around the Barents Sea to enhance China′s voice in Arctic affairs,put forward the research on global climate change and develop the geological theory on gas hydrate reservoirs in high-latitude waters.
