摘　　要：西南巴伦支海是挪威北极圈的一部分,具备天然气水合物富集成藏的有利地质条件,且存在明显的天然气水合物识别标志。本文收集和整理了巴伦支海西南地区与天然气水合物相关的资料,发现BSR、空白反射带和浅部气体聚集异常反射等地球物理标志主要在Loppa高地西部和Hammerfest盆地西部广泛分布;麻坑、气烟囱、断裂及其他气体渗漏构造地质标志主要在Asterias复合断裂带附近和Hammerfest盆地西部密集分布。因此,西南巴伦支海天然气水合物的有利勘探目标区主要是Loppa高地西部和Hammerfest盆地西部。结合区域地质背景分析上述各种识别标志的平面分布特征,推断该区天然气水合物的富集成藏与有效的含气流体运移通道密切相关。The Southwestern(SW)Barents Sea is a part of the Arctic Ocean located north of Norway.The geological conditions in the SW Barents Sea are suitable for the formation of gas hydrate.There are obvious identification marks of gas hydrate.The data related to gas hydrate in SW Barents Sea are collected and sorted in this paper.The finds are concluded as following.Geophysical signs are pointed in the western part of the Loppa High and the western Hammerfest Basin,such as the bottom simulating reflectors(BSR),enhanced reflections,and shallow gas accumulations.Pockmarks,gas chimneys,gas leakage faults and other geological signs also distribute in Asterias Fault Complex and in the western Hammerfest Basin.Therefore,the western part of the Loppa High and the western Hammerfest Basin of SW Barents Sea are the main gas hydrate favorable exploration target areas.The analysis of all kinds of identification markers of gas hydrate and geological conditions infer that gas hydrate deposits are closely related to the fluid migrating pathways in the SW Barents Sea.
