摘要: 通过对云南保山盆地气源岩有机碳含量、源岩可溶有机质、族组分特征、镜质组反射率、岩石热解参数分析,认为绝大多数源岩样品已达生油岩标准, 该盆地源岩处于未成熟阶段; 通过气源岩有机质饱和烃色谱特征分析, 认为该区有机质沉积时期主要为弱氧化-弱还原环境, 有机质以高等植物输入为主; 通过烃源岩可溶有机质碳同位素研究, 认为保参1 井有机质母源以高等植物为主, 沉积环境主要为沼泽相。

关键词: 云南, 气源岩, 饱和烃, 碳同位素, 未成熟

Abstract: The analyses of organic carbon content, soluble organic matter, group composition, vitrinite reflectance and rock pyrolysis parameter from gas source rocks in Baoshan basin show that most samples have reached to criterion of oil generating rock on the stage of immature. The chromatographic analysis of saturated hydrocarbon indicates the weak oxidation/weak reduction environment appeared in stage of organic matter deposition, supplied dominantly by higher plants. The soluble organic carbon isotope study suggests that the organic parent materials in Well Baocan-1 are dominated by high plants with swamp facies in sedimentary environment.

Key words: Yunnan province, gas source rock, saturated hydrocarbon, carbon isotope, immature
