| 摘 要： | 通过对云南保山盆地第三系岩性相、粒度分析、地震相和测井相的研究，结合层序分析，将盆地沉积体系划分为冲积扇沉积体系、扇三角洲沉积体系、河流三角洲沉积体系和湖泊沉积体系，它们在平面上和垂向上的有机组合与配置构成了盆地的演化模式，沉积体系的展布控制了储层和烃源岩的分布。从有机质丰度、成熟度等方面讨论了盆地烃源岩的地球化学特征，探讨了盆地的含气远景，指出云南第三系盆地应以寻找浅层生物成因天然气为主的勘探思想。

| Abstract: | Based on the study of lithofacies analysis, grain size data, seismic facies and well logging facies combining with the sequence analysis, the depositional system from Baoshan fault basin can be divided into five main sedimentary systems, that is, alluvial fan system, fan delta system, fluvial delta system, lake system and fluvial system. The depositional system controlls the distribution of source rock and reservoir. The paper discusses the feature of geochemistry and gas bearing prospects in Baoshan Basin from the type and maturity of organic matter in source rock. It suggests that in the Tertiary Basin of Yunnan, the biogenetic gas in shallow layer must be explored dominantly. |
