摘要：

根据凝析油中轻烃的烷基化程度和芳构化程度,C6、C7和 C8烃类的族组成,本文将四川盆地的凝析油分成了五大类:(1)成熟陆源母质生成的凝析油;(2)高成熟陆源母质来源为主的凝析油;(3)成熟湖相腐泥母质来源为主的凝析油;(4)高成熟海相腐泥母质来源为主的凝析油;(5)高成熟混源凝析油。

Abstract:

According to the Paraffinicity and aromatizaion of light hydrocarbons,the familycomponents of C6,C7 and C8 hydrocarbons in condensates,five types of condensates inSichuan basin are classified.1.Mature condensates from terrestrial materials.2.supermature condensates predominatly from terrestrial materials.3.Mature condensates from lacustrine sapropelites.4.Supermature condensates from marine sapropelites.5.Mixed supermature condensates from different origion.Other geochemical data confirm that the condensate classification on the characters of light hydrocarbons is reliable.
