摘　　要：中国近海海域主要含油气盆地目前找到的原油，依成熟程度可分为未成熟、低成熟、成熟和高成熟原油四大类。渤海湾盆地发现的原油从未成熟、低成熟至高成熟组成了一个完整的熟化序列；南黄海盆地、东海盆地和南海海域诸盆地找到的原油多数为成熟－高成熟原油，少数为低成熟原油，未成熟原油尚未找到。从有机质演化成烃的全过程分析，东海盆地、南黄海盆地和南海海域诸盆地具有寻找未成熟原油和低成熟原油资源的勘探潜力，应该引起应有的重视。Crude oils found in the major Chinese offshore petroliferous basins can be classified into four categories based on their maturity, i. e. immature, low mature, mature and high mature oil. Oils dis-coved in Bohai Bay Basin consist of a complete maturation series of immature, low mature, mature and high mature ones. Oils found in Sound Yellow Sea, East Sea Basin and Basins in South China Sea are mostly of mature to high mature ones, few low mature one and no immature one. It should be noted that there are exploration potentials to prospect for immature and few mature oil resources in South Yellow Sea, East Sea Basin and Basins in South China Sea according to the whole process of hydrocarbon evolution.
