摘要
信息不完全的系统为灰色系统,烃源岩的优劣与地质因素之间的相互关系是一种灰关系。灰色关联分析方法是一种很好的简单易行的烃源岩定量评价方法,弥补了地质定性评价方法的不足。敦煌盆地白垩系和侏罗系烃源岩评价等三个实例分析表明灰色关联分析方法与地质评价和有机岩石学评价结果基本相符。
An incomplete information system is called as gray system. Mutual relation of source rock quality and geol- ogy factor is a gray relation. Gray correlation analysis method is a good and easy one in quantitative evaluation on source rock and makes up for geological qualitative evaluation method. Examples analysis of evaluation on source rock of Cretaceous system and Jurassic system In Dunhuang Basin shows that gray correlation analysis method gets a result close to one geological evaluation method or organic lithology evaluation method gets.
