松辽盆地北部黑帝庙油层烃源岩条件初步探讨

Hydrocarbon source rock condition of Heidimiao Reservoir in Northern Songliao Basin

通过对松辽盆地北部烃源岩有机质丰度、类型、成熟度等有机地化参数分析, 确定嫩一段、青山口组是齐家-古龙凹陷的主力烃源岩, 青山口组是三肇凹陷的主力生油岩; 通过油源对比, 确定嫩江组一段是黑帝庙油层主要的烃源岩, 部分原油来自姚家组以下地层。

This paper analyzes the richness,type and maturity of the organic matter of the hydrocarbon source rock in northern Songliao Basin and determines that Nen 1 Segment and Qingshankou Member are the major hydrocarbon source rocks of Qijia-Gulong Sag,and Qingshankou Member is the major hydrocarbon source rock of Sanzhao Sag.The source rock correlation shows that Segment 1 of Nenjiang Member is the major source rock of Heidimiao Reservoir,and part of the oil originates from the formation below Yaojia Member.
