本文在分析济阳坳陷地质特征的基础上,结合烃源岩及大油田原油标志化合物的对比,确立和描述了Es_1-Es_(3下)—Ng_上(!)与Es_(3中)-Es_(3中)—Es_2-Es_4上(!)二大含油体系,并指出这二大含油体系控制了济阳坳陷大油田的分布。
Based on the analysis of the geological characteristics of Jiyang Depression and the comparison of the source rocks and the oil-bearing compounds in large oil fields, the relationship between Es_1-Es_ (3 lower) -Ng_ (Es) and Es_ (3) -Es_ (3) -Es_2-Es_4, and points out that these two major oil-bearing systems control the distribution of large oil fields in Jiyang depression.
