| 摘 要： | 本文以沉积学、石油地质学和油气地球化学等为基础,对川东北地区的上二叠龙潭组烃源岩进行了研究。通过分析,认为川东北龙潭组主要发育泥质烃源岩,这套优质烃源岩具有厚度大、有机质丰度高和演化程度高的特点。烃源岩干酪根的碳同位素显示烃源岩有机质为Ⅱ2、Ⅲ型,生烃史分析烃源岩主要生烃高峰期为晚侏罗世,时间较晚,对现今气藏贡献十分有利。

| Abstract: | Based on sedimentology,petroleum geology and organic geochemistry,Longtan Formation hydrocarbon source rocks of northeast Sichuan basin were studied in this text.By a great deal of analysis,it proves the high quality Longtan Formation of Upper Permian hydrocarbon source rocks possess big thickness and high contents of TOC.Kerogen carbon isotope shows organic matter of Upper Permian source rock is type Ⅱ2,Ⅲ.Hydrocarbon generative history shows that the generative oil fastigium of this set of source rock s is late Jurrasic apart.The oil and gas from Upper Permian hydrocarbon source rocks are favourable for present gas pools. |
