摘要： 通过原油生物标志物特征及其在追溯沉积环境、水体咸度、成熟度及母源先质等方面的分析,可将酒东盆地营尔凹陷原油分为两类：一类为营参1 井中沟组原油;另一类是以酒参1 井、长101 井和长2 井原油为代表的油。两类原油在成熟度和生物标志物特征等方面存在着显著差别。油源对比结果表明,营参1 井中沟组原油主要来源于中沟组源岩,是该套源岩未成熟- 低成熟阶段的产物,属未成熟- 低成熟油;而酒参1 井、长101 井和长2 井原油则主要源于营尔凹陷中南部的赤金堡组和下沟组下部的源岩,其源岩成熟度较高、沉积环境较偏酸性,含粘土的菌类沉积有机物是其主要生烃母源。

Abstract: Through analyses of the biomarker characteristic and its effect on sedimentary setting, water salinity, maturity and parent material, the crude oil from Ying'er sag in Jiudong basin can be classified into the crude from Zhonggou formation in Yingcan-1 Well and the crude from Jiucan-1 Well, Chang-101 Well and Chang-2 Well. These two types of crude oils are distinct in maturity and biomarker characteristic. The source correlation result shows that the former crude mainly originates in the source rock of Zhonggou formation, being a product of immature to low-mature phases, hence regarded as immature-low mature crude; the latter primarily originates in those of Chijinbu formation and Lower Xiagou formation in mid-south part of Ying'er sag, and high maturity, partial acid sediments and bacterium depositional organic matters with clay minerals are its major sources.

Key words: Jiudong basin, biomarker, source correlation, sedimentary environment
