| 摘 要： | 本文系统地研究了保山盆地保参１井第三系成烃地球化学特征，并对其油气显示，天然气成因及古地温进行了探讨，研究结果表明，盆地第三系虽然具有一定规模的形成烃源岩的物质基础，但其有机质成熟度表现偏低，羊邑组（Ｎ２ｙ）属于未成熟带，南林组（Ｎ１ｎ）属于低成熟带，成熟的烃源岩展布规模有限，生物成因天然气及未成熟，低成熟油是保山盆地主要的油气资源。

| Abstract: | The characteristics of Tertiary Hydroca rbon-forming geochemistry, oil and gas indication, origin of natural gas and its palaeotemperature of Baochan Well 1 in Baoshan basin are systematically studied and discussed. Though abundant hydrocarbon forming source rocks exist in the basin, the maturity of organic material remains low, which is characterized by the immature belt of Yangyi Formation and low mature belt of Nanling Formation. The research leads to the recognition that the distribution of hydrocarbon forming source rocks is limited and the biogenic natural gas and immature low mature oil are the main oil and gas resources in the Baoshan basin. |
