中国陆上剩余油气资源潜力及其分布和勘探对策

我国陆上油气资源十分丰富，经过半个世纪的勘探取得了举世瞩目的成就。但总体上看，资源探明程度还不高，油、气探明率分别为26.9%和5.4%，未探明的资源量还很大。石油剩余资源的42.4%分布在东部的裂谷盆地，46%分布在西部的叠合盆地；天然气剩余资源的37%分布在中部的四川盆地和鄂尔多斯盆地，28.1%分布在西部的塔里木盆地。剩余油气资源虽丰富，但质量偏差，勘探难度大，勘探成本高。21世纪前十年的油气勘探将面临诸多严峻挑战。为确保石油天然气工业的持续发展，不仅要开展基础理论研究，还必须建立、健全风险勘探机制和经济评价决策系统，进一步发展先进适用的勘探技术，开辟新的勘探领域，发现更多的商业储量，确保我国油气产量稳中有升。表4参9（窦立荣摘）

Potential, distribution and exploration strategy of petroleum resources remained onshore China

Petroleum resources onshore China are abundant, through half century of exploration a great achievement has been made in China. However, its exploration degree onshore is not high, the proved ratios of oil and gas are 26.9% and 5.4%, respectively. The undiscovered resources are still very large. About 42.4% of remaining oil resources is in the rift basins of East China and 46% in the superimposed basins of West China. About 37% of remaining gas resources is in the Sichuan and Ordos basins of Central China and 28.1% in the Tarim basin. Although the remaining resources are abundant, their quality is relatively poor, the exploration difficulty is big, and the exploration cost will increase greatly. As a result, the petroleum exploration will face a great challenge in the next decade. In order to keep the sustainable growth of petroleum industry and open new exploration frontiers to find more commercial oil and gas reserves, basic theory research should be carried out, risky exploration mechanism and economic evaluation and decision making system should be established and strengthened, and advanced and practical techniques should be developed.
