摘要
通过对采集的岩样进行地球化学综合分析,得出金羊盆地北票组为盆地主要烃源岩,为盆地油气生成提供了物质基础;北票组烃源岩有机质丰度不高,属差—中等烃源岩;干酪根类型以腐殖型为主,成烃母质为陆地高等植物;金羊盆地北票组烃源岩已经进入成烃门限,并处于成熟阶段中的低成熟到中成熟阶段。
In order to evaluate the hydrocarbon source rock in Jinlingsi-Yangshan Basin, based on the geochemical comprehensive analyses of collected rock samples, conclusion are obtained that the Beipiao Formation is the main hydrocarbon source rock and provides the substance foundation for oil and gas formation. The organic abundance of Beipiao Formation hydrocarbon source rock is not very high and belongs to poor to middle grading. Kerogen type is mainly humic, and terrestrial higher plants are the petrologen. The Beipiao Formation hydrocarbon source rock has come into threshold of hydrocarbon forming and belongs to low-middle maturity stage.
