摘要：为了有效评价东三段烃源岩并明确其油源贡献，以大量的钻井、地球化学以及油气勘探资料为基础，基于烃源岩评价的特征参数及油源对比方法，探讨了东营组烃源岩特征及烃源岩对油气成藏贡献。研究结果表明：东营组有效烃源岩主要发育于东三段，其w（TOC）平均为1.1%1.2%，最高可达7.8%以上，为好烃源岩，有机质类型以且型为主，成藏期（距今2Ma）R。值为0.7%~0.9%，处于大量生油高峰，最厚的有效烃源岩位于林雀洼陷与柳南洼陷，其次为曹妃甸洼陷；与沙一段和沙三段相比，东三段典型的生物标志化合物特征为Pr/ Ph值高以及伽马蜡烷/C，霍烷值低，以此可较好地与沙一段和沙三段烃源岩进行区分。油源对比结果表明，现存的东营组烃源岩贡嵌的原油主要呈环状分布于柳南注陷以及林雀注陷附近，普妃旬洼陷附近仍有较大勘探潜

Abstract : In order to effectively evaluate the hydrocarbon source rocks of Member Ed, and made clear of their con-tributions to the oil source, on the bases of the data of the great number of the well drlling, geochemical and the petroleum exploration achievements, with the help of the evaluated characteristic parameters and oil source correla-tion of the hydrocarbon source rocks, the rock characteristics and contributions to the hydrocarbon accumulation were explored for the source rocks in Dongying Fomation. The study achievements show that the effective source rocks with the averaged TOC of 1. 1% to 1. 2%, and the maximum of 7. 8% or above are mainly developed in Mem-ber Ed,, and moreover they are much better source rocks taking Type II Kerogen as the principal form, the R, of the aceumulation period (2 Ma) most source rocks is between 0. 7% and 0. 9%, and moreover in the peak oil-gen-erating period, the most thickest effective source rocks are distributed in Linque Low and Liunan Low, the nest is Caofeidian Low; comparing with Member Sha-l and Sha-3, the characteristics of the typical biomarkers in Member Ed, are shown as much higher Pr/Ph value and lower gammacerane/C, hopane value, this can be easily distin-guished with the hydrocarbon source rocks in the former two members. The results of the oil-source correlation show
