摘要
油气资源量是一个动态的量值,世界油气资源评价结果总体上随着时间的推移而呈逐渐增多的趋势,而且随着科技的不断进步和经济条件的改善,扩大了油气资源的领域,世界油气储量和产量保持了持续增长的态势。1991年-2008年期间,世界石油和天然气剩余可采储量分别增长了39.80%和39.56%,石油和天然气产量分别增长了24.27%和53.16%。随着勘探、开发、储运和加工配套技术的进步,天然气将继续得到快速发展,21世纪初是天然气发展的黄金时期,预计在2025年前后世界能源消费将由石油时代进入天然气时代。预计今后相当长时间内,世界油气剩余可采储量仍将保持上升态势,21世纪世界油气资源总体上是充足的,不会出现油气短缺,油气产量完全可以满足经济发展的需要。
The amount of petroleum resources is a dynamic value,which can be changed with development of theory,increases of knowledge,progress of technical methods and changes in economic conditions.According to the results from the world oil and gas resources assessment by United States Geological Survey（USGS）,the world oil resources increased from 233.75 billion tons in 1984 to 410.85 billion tons in 2000,an increase of 75.74%;natural gas resources increased from 210.4 billion tons of oil equivalent in 1987 to 419.2 billion tons of oil equivalent in 2000,an increase of 99.24%.Moreover,with technological advances and amelioration of economic conditions,exploration of petroleum resources has been expanded.The oil and gas reserves and the output maintains sustained growth.The world remaining recoverable reserves of oil increased from 138.05 billion tons in 1991 to 192.99 billion tons in 2008,an increase of 39.80%;the world remaining recoverable reserves of natural gas increased from 132.58 trillion cubic meters in 1991 to 185.02 trillion cubic meters in 2008,an increase of 39.56%;the world oil production increased steadily from 3.162 billion tons in 1991 to 3.929 billion tons in 2008,an increase of 24.27%;the world＇s natural gas production rose rapidly from 2.0015 trillion cubic meters in 1991 to 3.0656 trillion cubic meters in 2008,an increase of 53.16%greater than that of the oil.With the progress of supporting technology in exploration,development,transportation,storage and processing,natural gases were exploited fast in the past,indicating that the ratio of natural gases in primary energy consumption increased from 21.7%in 1991 to 24.1%in 2008.However,the ratio of oil in primary energy consumption decreased from 38.6%in 1991 to 34.8%in 2008.It is expected that the beginning of the 21st century is a golden development age for natural gases.The world energy consumption will be at the age of natural gases around the year 2025.Since then over a very long period of time,the world energy constitution structure will be dominated by utilization of natural gases.Other traditional sources of energy（e.g.,oil and coal）and new energy are expected to co-exist and complement with each other.The world remaining recoverable reserves of oil and gas will keep rising in quite a long period.It was projected that in the 21st century petroleum resources in the world would be essentially sufficient.There would not be short of oil and gas,fully satisfying needs for social and economic development.
