摘要: 应用生物标志化合物分析技术,对胶莱盆地白垩系莱阳组烃源岩的甾萜烷和芳烃化合物进行了测试。结合分析结果对烃源岩的有机质生源构成、沉积环境和成熟度等进行了讨论。研究结果表明该烃源岩发育的沉积环境为缺氧还原的微咸水-咸水的半深湖-深湖环境;有机母质来源主要以低等水生生物,尤其是原生生物和细菌为主,混有少量陆源高等植物;烃源岩的成熟度明显已进入生油窗,逍仙庄段以成熟晚期和高成熟为特征,水南段正处于最佳生油期。

Abstract: The steranes, terpenoids and aromatic compounds from source rocks of Cretaceous Laiyang formation in Jiaolai basin were measured by means of technologies of biomarkers analysis, along with discussion of organic matter constituents, sedimentary environment and maturity of the source rocks. Study results show that the depositional environment for source rocks development is a reducing brackish water-saline half deep lake-deep lake one; the organic source materials originated from lower aquatic organ-isms (especially protist and bacterium) mixed with few terrestrial higher plants; the source rocks have maturities of entering oil threshold, such as that Xiaoxianzhuang member is characterized by high maturity and up to late maturity; Shuinan member is just in stage of the best oil generation.

Key words: Jiaolai basin, Cretaceous, source rock, biomarker compound
