中国西部地区石油资源潜力与开发前景

POTENTIALITY AND PROSPECT OF OIL AND GAS RESOURCES DEVELOPMENT IN WESTERN CHINA

中国西部地区是中国石油工业的发祥地 ,也赋存有丰富的油气资源。据估算西部地区有石油资源 41 5 9× 1 0 8t,占全国石油资源的 3 9 3 3 % ;西部地区有天然气资源 2 4740 0× 1 0 8m3,占全国天然气资源的65 1 %。而 2 0 0 0年西部地区的石油产量 2 80 5× 1 0 8t,仅占全国当年石油产量的 1 7 2 2 % ,与其资源不相匹配。目前西部地区石油资源平均探明率仅为 9 83 % ;天然气资源平均探明率仅为 5 9% ,油气资源勘探还有很大潜力。因此 ,加快西部地区油气资源的开发利用 ,可以部分弥补东部地区的石油产量递减 ,缓解我国石油需求增长与石油供给的矛盾 ,促进西部地区经济的发展。但是西部地区地面地形复杂、交通不便 ,生态系统脆弱 ,油气勘探开发技术难度很大 ,油气勘探效益难以保障。去年中央已制定了西部大开发的优惠政策 ,借“西部大开发”契机 ,在自主勘探开发的同时引进外部技术和资金 ,加快西部油气资源开发。同时应该严格执行环境保护和矿权管理法规 ,规范油气开发秩序 。

Being the origin of China's petroleum industry, the west of China is abundant with oil and gas resources. It is estimated that there are 415 9×10 8t oil resource and 247 400 ×10 8t gas resource in the west, accounting for 39 33% and 65 1% of China's total, respectively. While in regard of petroleum output in the west, it is only 2 805 ×10 8t and accounts for 17 22% of China's total, not matching with resources endowment. The rates of proved reserves for oil and gas resources in the west are only 9 83% and 5 9% respectively, which indicates that the potentiality of oil and gas resources in the west is great. Therefore, it argues that accelerating exploitation of west oil and gas resource will compensate for the oil production decline of eastern China, maintain petroleum production stable, bridge the gap between demand and supply of oil, besides, economic development of the west of China can be advanced. Furthermore, it suggests that regulations on environmental protection and exploitation rights should be strictly carried out and the order of oil and gas exploitation should be standardized.
