摘要
辽东湾海域在不同的构造部位及同一构造的不同层系，原油的物理化学性质差异很大．不同层系及同一层系生油岩的生物标志化合物特征亦不完全相同．以生物标志化合物的分布特征为基础，并综合其它资料，对辽东湾海域的原油及生油岩特征进行了分析．结果表明，在该区不仅有低成熟原油、成熟原油，并且还发现有未成熟原油．这可作为今后勘探的目标之一．该区沙三段生油岩分布广，沉积厚度大，母质类型好，成熟度高，为主要生油层系．
The physical and chemical properties of the crude oil are different considerablyin different strata of the same structure at Liaodong Gulf. Also, the characteristics of the biological markers are not alike in different strata,as well as in the same stractum. According to the distribution of the biological markers and other data,the characteristics of the crude oil and the source rocks are analysed, and a systemetic classification of the crude oil is present.It is sure that Es_3 section is the main source rocks in the sea area.
