世界海洋油气资源勘探潜力及利用前景

Potential of Global Offshore Petroleum Resource Exploration and Utilization Prospect

世界海洋油气资源非常丰富。随着经济快速发展和陆上油气勘探的日趋成熟,对海洋油气资源的勘探与开发已逐步成为全球油气利用的热点。通过对美国地质调查局(USGS)和美国IHS公司等石油机构的数据库资料分析,认为目前世界海洋油气探明可采储量为13215亿桶(约1802.53×108t)油当量,占全球含油气盆地总储量的35.8%;主要分布在全球近海的12个区域。海洋待发现的常规油气资源分布很不均匀。通过对全球海洋重点盆地待发现油气规模与勘探状况分析,认为具有一类勘探潜力级别和二类勘探潜力级别的盆地或区带共16个;处于中等勘探程度的10个盆地待发现油气资源占全球海域油气资源总量的42%,展现出很好的勘探前景。

World offshore petroleum resource is abundant.With rapid economic development and onshore exploration becoming mature,the exploration and development for offshore petroleum resource has gradually become a hot spot.Two databases of IHS and USGS（United States Geology Survey） suggested that the recoverable oil and gas reserve would be 1321.5 billion barrels oil equivalent,about 35.8% of world total petroleum reserve.They are distributed in 12 regions around offshore.The undiscovered oil and gas resources in offshore are not uniformly distributed in the world.By statistics of undiscovered petroleum resources and exploration layers in the main global offshore basins,the first and second class potential exploration areas are 16 basins,10 of which was in the moderate exploration degree for undiscovered oil and gas resources,accounting for 42% of total resource.So it is good target for petroleum exploration.
