南美洲油气资源与勘探开发潜力

Oil-gas Resources and Exploration and Development Potential of South Africa

南美洲是世界上重要的油气产区之一,目前年产油气总量在3×108t以上(油当量),剩余探明原油可采储量为134×108t,剩余探明天然气可采储量为7×1012m3,储产比远远高于世界平均水平,其中委内瑞拉、巴西、厄瓜多尔、哥伦比亚、秘鲁等国具有较大的油气勘探开发潜力。通过讨论南美洲的地质背景,从盆地分析出发,将南美洲沉积盆地分为5个类型,并讨论它们的分布特征与含油气性的差别。根据南美洲各国油气资源状况和勘探程度,认为南美洲必将成为目前及未来若干年内全球油气勘探的热点;无论从资源状况还是投资环境看,南美洲各国均是中国在对外合作勘探开发的国家地区中占有极强吸引力的地区之一。

South America is one of the main oil and gas producing areas in the world,of which the annual oil and gas output(oil equivalent),residual proven recoverable crude oil and gas reserves are more than 300 million tons,13.4 billion tons and 7 billion cubic meters respectively,and the reserve-production ratio is far higher than the average world level.Such countries as Venezuela,Brazil,Ecuador,Colombia,and Peru have great potential for oil and gas exploration and development.Based on presenting the geologic background of South America,this paper divides the sedimentary basins there into five types and discusses the distribution characteristics and the difference of oil-gas resources of each type.South America is supposed to become the main area of exploration for oil and gas in the world in the future years on the basis of analyzing the oil and gas resources and their exploration in different countries in South America,all of which are the most appealing cooperators of China in oil-gas exploration and development in the world.
