Abstract: The major development in the study of spore-pollen GAI in last decade by petroleum spore-pollen workers in china is delt with in this paper.A spore-pol-len GAI clasfication standard and its correlation with those used by domestic and foreign collegues are defined.A table demonstrates the relation betweenspore-pollen GAI and generation stages of continental Tertiary hydrocarbon-bearing basins in china is presented.Some applications of spore-pollen GAI data are discussed.The au-thor further proves that spore-pollen GAI is a composites results of the effects of temperature,time and nature of the source rock.The significance of using spore-pollen GAI in searching for good source rock and promising source region is emphasized.

摘要： 本文总结了石油孢粉工作者近十年来在孢粉化石色变研究上的主要进展.明确了孢粉色级划分的行业标准和国内外有关色级划分的对应关系.提出我国陆相第三系含油气盆地孢粉色变和油气形成阶段的对应关系表.对孢粉色变资料的若干应用问题进行了探讨.进一步论证孢粉色变是温度、时间和生油岩母质类型综合影响的结果.指出利用孢粉色变资料,在确定良好生油岩、寻找有利生油区上的重要意义.
