摘要

摘要: 通过详细的油气地质特征研究及油(气)源对比,确定了珠三坳陷的主力生、储、盖层。根据广义的油气系统概念和研究方法,结合构造和沉积特征分析,对坳陷进行了油气系统研究。研究表明,在不同的地质历史阶段,珠三坳陷中油气系统发育具有不同的特征,即早期(渐新世晚期—早中新世)只在文昌A凹陷中发育一个石油系统,而到了晚期(中中新世—上新世)则在多个凹陷及凸起上发育多个油气系统。此外,对每个油气系统的特征及其中的油气运移规律和成藏特征进行了探讨,并提出了勘探建议。

Abstract: Based on the study of petroleum geological features in Zhu-Ⅲ Subbasin of South China Sea,the authors determined the main sources,reservoirs and caprocks in the subbasin by analysizing the relationship of oil(gas)and source rocks in this paper.Moreover,according to the newest definition of petroleum system,the author identified the petroleum systems in Zhu Ⅲ Subbasin by analysizing the characteristics of its tectonics and deposition.The study indicated that there were different oil(gas)systems in Zhu Ⅲ Subbasin at different periods.Namely,there were only one oil system in Wenchang A depression in the early and five oil(gas)systems in the whole subbasin in the late.Finally,the authors also studied the rules of oil(gas)migration and the features of pool forming in these systems.
