摘要

摘要: 通过对渤海湾盆地沾化凹陷富林洼陷原油的生物标志物分布与组合特征分析,认为该区主要存在3类原油:Ⅰ类原油主要分布于东次洼,呈植烷优势,伽马蜡烷含量高,重排甾烷与4-甲基甾烷含量较低,来源于东次洼本身的沙四上亚段烃源岩;Ⅱ类原油分布于中次洼洼陷内部,具有姥鲛烷优势、伽马蜡烷含量低、重排甾烷含量高的特征,纵向上不同储层油气来源存在差异,其中浅部储层油气来源于孤南洼陷沙三下亚段烃源岩,深部储层油气主要来自于富林洼陷沙三下亚段烃源岩;Ⅲ类原油分布于中次洼断裂带附近,成熟度较低,姥鲛烷优势,伽马蜡烷含量中等,C₂₈甾烷含量丰富,孕甾烷和重排甾烷含量较低,为孤南洼陷沙一段与富林洼陷沙三下亚段烃源岩所形成的混源油。

Abstract: Based on the studies of biomarker distribution and composition of crude oils in the Fulin sub-Sag of the Zhanhua Sag of the Bohai Bay Basin, there are 3 types of crude oil in the study area. The crude oils of type Ⅰ mainly exist in the east of the sub-sag, characterized by low Pr/Ph ratio, high gammacerence content as well as low diasterane and 4-methyl-sterane contents. They are originated from source rocks in the upper subsection of the 4th member of the Shahejie Formation in the east of the sub-sag. The crude oils of type Ⅱ mainly locate in the center of the sub-sag, featured by high Pr/Ph ratio, low gammacerence content and high diasterane content. The origin for oil and gas is different vertically. Hydrocarbon in the middle and shallow reservoirs is mainly originated from source rocks in the lower subsection of the 3rd member of the Shahejie Formation in the Gunan sub-Sag while hydrocarbon in the deep reservoir is mainly originated from source rocks in the lower subsection of the 3rd member of the Shahejie Formation in the Fulin sub-Sag. The crude oils of type Ⅲ mainly distribute around fault belts in the central sub-sag, featured by low maturity, high Pr/Ph ratio, medium gammacerence content, high C₂₈ sterane content as well as low pregnane and diasterane contents, which show mixed-oil characteristics of source rocks from both the 1st member of the Shahejie Formation in the Gunan sub-Sag and the lower subsection of the 3rd member of the Shahejie Formation in the Fulin sub-Sag.
