| 摘 要： | 北极地区具有超过4 000亿桶油当量的待发现技术可采储量, 是未来全球油气勘探与开发的重要增长点。本文按照地理和地质构造因素将北极地区分为北冰洋海盆区和环北极含油气区（含潜在含油气盆地）,按照板块演化及盆地发育历史将后者划分为北太平洋极地盆地群、俄罗斯极地盆地群和欧洲极地盆地群。根据大量文献和IHS数据, 结合生油层、储层、盖层及圈闭特征方面的研究, 系统对比、分析北极地区石油、天然气分布特征:北太平洋极地盆地群重要烃源岩形成于侏罗纪和白垩纪, 盆地群中重要储层大部分都分布于新生界布鲁克斯层, 油气系统以构造圈闭为主。俄罗斯极地盆地群中多数盆地具有古生代基底, 受斯堪的纳维亚早古生代造山期变形、西伯利亚板块古生代西部造山变形影响, 60%以上的烃源岩产自中生界, 储层以中生界前陆、克拉通盆地沉积物为主,盖层分布较广, 以中生界居多。欧洲极地盆地群受控于北大西洋洋脊的扩张和迁移, 各盆地烃源岩分布于中生界, 大部分储层分布于上白垩统—古新系, 自生自储、古生新储为该区域盆地的主要成藏模式。其中, 俄罗斯极地盆地油气储量最多, 占北极地区总储量45%以上且勘探潜力最大。

| Abstract: | As undiscovered, technically recoverable resources, there are over 400 billion barrels of oil(equivalent) in Arctic region which plays a significant role in future exploration and exploitation. This paper divided the Arctic region into Arctic sea area and circum-Arctic petroliferous basins based on geographic and geologic factor. Three basin groups- North Pacific basin group, Russian basin group and Western Europe basin group constitute the circum-Arctic petroliferous area according to tectonic evolution and the basin development history. Based on IHS data base and other information, this paper analyses the petroleum characteristics with paleoenvironment. The primary source rock in North Pacific basin group formed in Jurassic and Cretaceous. Main reservoir located in Brookian Sequence mostly. Basins in Russian basin group have Paleozoic basement. 60% of the source rock and major reservoir which composed by marine sediment are from Mesozoic while the significant cap rock located in Mesozoic. Western Europe basin group's source rock and reservoir both located in Mesozoic up to the expansion and move of North Atlantic Ocean Ridge. Self-generating is the main hydrocarbon accumulation mode. Russian basin group has a majority reserves which occupies over 45% in total reserves and contains great exploration potential. |
