摘要
全球海洋油气资源丰富,海洋石油资源量占全球石油资源总量的34%,探明率在30%左右,尚处于勘探早期阶段。由于海洋特殊的环境,海上油气勘探的投资大幅增加,一般是陆地油气勘探投资的3～5倍。海洋油气勘探以海上拖缆地震勘探为主要手段。海上勘探阶段划分为初步勘探阶段和进一步勘探阶段。初步勘探阶段包括盆地评价、区块与圈闭评价、发现油气藏;进一步勘探阶段则以钻探井和评价井为主,以扩大含油气面积,增加和探明油气地质储量。墨西哥湾、西非及巴西等海域将继续引领全球海洋油气勘探潮流,发达国家的油气勘探技术日渐成熟。
Marine oil and gas resources are abundant and take up about 34% of the whole world.They are still in the early states of exploration with proven rate being 30%.Because of special marine environment,the investment on marine oil and gas exploration increases dramatically,generally three to five times higher than that on land-based exploration.Marine oil and gas exploration takes the marine towing seismic exploration as a primary means. The marine exploration phase is classified into the preliminary exploratio...
