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。
Based on the lithologic facies, grain size analysis, seismic facies and logging facies of the Tertiary in the Baoshan basin, Yunnan, the sedimentary system of the basin is divided into alluvial fan sedimentary system, fan delta sedimentary system, deltaic sedimentary system and The lacustrine sedimentary systems, whose organic combination and configuration in the plane and in the vertical, constitute the evolutionary pattern of the basin, and the depositional system controls the distribution of the reservoir and source rocks. The geochemical characteristics of source rocks in the basin are discussed from the aspects of abundance and maturity of organic matter. The gas potential of the basin is discussed. It is pointed out that the exploration thought of finding the shallow biogenic gas in the Tertiary Basin in Yunnan should be pointed out.
