我国油气资源潜力及勘探领域

Oil & Gas Resources Status and the Exploration Fields in China

我国是一个油气资源比较丰富的国家,尽管一些长期勘探的主要含油气盆地的勘探程度较高,但剩余油气资源的总量还比较丰富,具有进一步加快发展的资源基础。经过几十年的油气勘探,我国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。未来我国油气勘探的领域还比较广阔,不仅有成熟盆地精细勘探、岩性、前陆及叠合盆地中下组合等四大现实领域,还有青藏、南海南部、海相碳酸盐岩及“低品位”资源等油气勘探新领域。

Oil and gas resources are abundant in China. Although the exploration extent of the main petroliferous basins is high after long time exploration, the amount of remained oil and gas resources is still large, and it has the resource base for further development. After oil and gas exploration in tens of years,the preservation conditions of remained oil resources become worse￡?and the proportion of low- quality resources was augmented,the remained oil and gas resources in subtle oil and gas reservoirs is enlarged￡?and oil and gas exploration is getting more difficult. Oil and gas exploration field in China will be broad in the future, not only has four big realistic exploration fields, include the fine exploration in mature basin, the litho-stratigraphic reservoirs, the foreland and the lower-medium combination of superimposed basin, but also has some new exploration fields like Qinghai and Tibet, the south of the South China Sea, the marine carbonate rocks and 'low-quality' resources.
