摘　　要：选用在很长地质历史中都广泛分布的松粉（Ｐｉｎｕｓ）作为高温高压釜热模拟的实验样品，收集热压模拟中的气态、液态、固态产物，并对其进行孢粉学和地球化学研究，认为孢粉具有两期生烃高峰：孢粉中内含物参与了早期的未熟—低熟油的生成，孢粉素则为成熟期的主要成油母质。建立了孢粉生烃模式，为研究未成熟—低成熟石油的生成机制提供了实验依据。The palynological and geochemical characteristics of gaseous, liquid and solid products produced during thermopressurized simulation of Pinus , the wide distributed sporopollen, have been studied, and the hydrocarbon generation modal of sporopollen has been presented in this paper. The modal suggests that the sporopollen has two hydrocarbon generation peaks, its inner matter (organs) has contributions to the generation of early immature low mature oil, and sporopollen is the main source matter for the mature oil.
