Abstract:

Petroleum is the important strategic material related to the security of national politice,economy and military affairs,and it is also the power of economic development.The indemnification of petroleum supply and demand directly influences the stabilization of the state economy and the safety of society to a large extent.Oil and gas resources are abundant in China.The amount of remaining oil and gas resources is still large although the exploration extent of the main oil-bearing basins onshore is high.After oil and gas exploration in tens of years,the preservation conditions of remaining oil resources became worse,and the proportion of low-quality resources was augmented.The concealment of remaining oil and gas resources is boosting up,and oil and gas exploration is getting more difficult.Therefore,the oil and gas exploration in future should depend on the advancement of science and technology as well as reduction of cost,in order to increase the reserves and benefits.

Key words: oil and gas resources, remaining oil and gas resources, exploration potential, oil and gas distribution, assessment

摘要：

石油是国家政治、经济、军事安全的重要战略物质,也是国民经济发展的动力资源.石油的供需保障程度在相当大的程度上直接影响着国家经济的稳定和社会的安危.我国油气资源比较丰富,尽管陆上主要含油气盆地勘探程度较高,但剩余油气资源的总量不少.经过几十年的油气勘探,剩余油气资源的赋存条件变差,低品位资源所占比例增大,剩余资源的隐蔽性增强,勘探难度增大.因此,未来油气勘探必须依靠科技进步,并注意降低成本,才能实现油气勘探增储、增效.
