中文摘要：

渤海湾盆地断裂系统极其复杂,盆地内JZ油田太古宇潜山油藏平面上按断块系统可分为多个油区,由于潜山裂缝油藏储层强非均质性,油区内、油区间油藏连通关系难以明确。尝试利用石油色谱指纹技术对油田不同油区原油分别开展原油族群划分、原油生物标志化合物分析、原油同源性对比分析,根据单层原油指纹差异及混合原油的指纹变化特征,最终确定了JZ油田不同油区潜山油藏储层纵横向的连通性,有效指导了油田后续开发方案部署。

英文摘要：

The fault system of the Bohai Bay basin is famous for the complexity. The Archean buried hill reservoir of JZ oilfield in the basin can be divided into many areas according to the fault block system. The connectivity in and between the areas is difficult to define because of the strong heterogeneity. In this paper, with the help of oil chro-matographic fingerprint technology, we carry on experiments and analysis about the crude oil group division, bio-marker ,homology and so on. Finally we determine the vertical and horizontal connectivity of different areas in Archean buried hill according to the crude oil fingerprint differences and the fingerprint characteristics of mixed crude oil.
