摘要

摘要: 利用烃源岩“TOC”、热解、族组分、碳同位素和生物标志化合物检测等地球化学方法，对松辽盆地南部彰武、昌图断陷九佛堂组烃源岩和原油进行分析研究，发现彰武断陷原油来源于九佛堂组下段烃源岩，昌图断陷泉1井原油与九佛堂组上段烃源岩有较高的亲缘性。结合松南地区其他有工业油气发现的重要断陷九佛堂组烃源特征对比分析，认为九佛堂组为全区主力烃源岩，具有高丰度、多类型和低演化程度的特征，烃源岩分布与油气富集程度具有较好的对应关系。受断陷构造演化、沉积环境和埋深及后期保存条件等多种因素影响，九佛堂组下段烃源岩比上段烃源岩更具生烃潜力，成熟度是烃源岩重要的影响因素。进一步落实断陷内九佛堂组有机质成熟度、优质烃源岩发育层段和平面展布范围，寻找良好的源储配置和合适的近源圈闭是松南地区下一步的勘探方向。

Abstract: Source rock and crude oil samples from the Jiufotang Formation in the Zhangwu and Changtu depressions in the southern Songliao Basin were analysed for TOC content, pyrolysis yield, rock group composition, carbon isotope and biomarkers. The oil in the Zhangwu Depression was mainly sourced from the lower part of Jiufotang Formation, while that in the Changtu Depression mainly derived from the upper part of Jiufotang Formation. The Jiufotang source rocks in other depressions with industrial oil and gas discoveries in the study area were also studied, indicating that the Jiufotang source rocks were the main source rocks in the region, with high abundance, multiple types, and low evolution degree. The source rock distribution has a good relationship with the degree of hydrocarbon enrichment. Various factors such as structural evolution of the depression, sedimentary environment, burial depth, and later-stage preservation conditions result in more hydrocarbon production in the lower part of Jiufotang Formation relative to those in the upper part. Maturity is an important factor affecting source rocks. The development and distribution of high-quality source rocks in the Jiufotang Formation were determined. Finding a good source and reservoir configuration and appropriate near-source traps lead to favorable exploration directions in the southern Songliao Basin.
