摘要
对惠州凹陷HZ25-4-1井珠江组-文昌组砂岩储层进行了系统取样和生物标志物分析。利用烃类流体运移痕迹生物标志物分子示踪技术,结合生烃强度盆地模拟结果,初步判识惠州凹陷存在2类混源油,即文昌组中深湖相型原油与恩平组煤系型原油的混源和文昌组中深湖相型原油与浅湖相型原油的混源,证实了惠州凹陷文昌组浅湖相泥岩为有效烃源岩。这一认识对惠州凹陷成油体系的划分具有重要意义。
A systematic sampling and a biomarker analysis have been made in the reservoir sandstones of Pearl River-Wenchang Formation,well HZ25-4-1,Huizhou sag.It is preliminarily recognized,by using the biomarker tracing technique of hydrocarbons migration and combining with the basin modelling results of hydrocarbon-generation intensity,that there are two types of mixed-sourced oil in Wenchang Formation,Huizhou sag,which may be sourced from Wenchang Formation deep-lacustrine facies ＋ Enping Formation coal measures and Wenchang Formation shallow ＋ deep-lacustrine facies respectively.Therefore,the mudstone of shallow-lacustrine facies in Wenchang Formation may be an effective source rock.This perception is important to dividing petroleum systems in Huizhou sag.
