摘要

垦利16油田为莱州湾凹陷高含硫油田,原油普遍具有混源现象,而原油混源程度及分布特征并不明确。针对以上问题,综合运用生物标志化合物和饱和烃碳同位素法判识混源油,并对其混源程度进行定量分析。结果表明:垦利16油田原油普遍具有混源特征,平面上原油混源程度基本相当,纵向上原油混源程度与地层层位具有相关性,其中,沙三上亚段咸化型原油混入比例最高,平均值为89%,而沙三下亚段咸化型原油混入比例最低,平均值为25%。垦利16油田混源油的发现,证实了莱州湾凹陷主洼沙四段咸化烃源岩的贡献,预示着主洼及南部斜坡带深层沙四段蕴含着巨大的勘探潜力;首次明确南洼生烃和供烃能力,进而有望打开南洼围区的勘探局面。

Abstract

Kenli 16 Oilfield is located in the Laizhouwan sag with high sulfur content. Crude oil generally has mixed sources, but the degree and distribution characteristics of mixed sources of crude oil are not clear. In view of the above problem, biomarker compounds and saturated hydrocarbon carbon isotope methods were comprehensively used to identify mixed-source oil, and the mixed-source degree is quantitatively analyzed. The results show that the crude oil in Kenli 16 Oilfield generally has the characteristics of mixed sources, and the mixed-source degree of crude oil is basically the same on plane; in vertical direction, the mixed-source degree of crude oil is correlated with the strata. In which, the mixing proportion of salinized crude oil in the upper sub-member of the third Member of the Shahejie Formation is the highest, with an average of 89%; while that in the lower sub-member of the third Member of the Shahejie Formation is the lowest, with an average of 25%. The discovery of the mixed-source oil in Kenli 16 Oilfield confirms the contribution of salinized source rock to the fourth member of the Shahejie Formation in the main trough of the Laizhouwan sag, and indicates that the deep fourth member of the Shahejie Formation in the main trough and the southern slope zone contains great exploration potential. For the first time, the hydrocarbon generation and supply capacity of the southern trough is clearly defined, which is expected to open up the exploration situation in the periphery zones of the southern trough.

Key words： mixed-source oil; biomarker; carbon isotope of saturated hydrocarbons; source rock; quantitative judgment; Laizhouwan Sag
