摘要
烃源岩有机相按有机显微组份的组成及生烃潜量 ,结合沉积环境、地化相、干酪根元素原子比综合划分 ,确定四类有机相 :类脂富氢相、脂镜富氢相、脂镜贫氢相、镜质贫氢相。按上述资料综合编制了始新统、渐新统和中新统有机相图 ,指出了有利油气生成的区带 。
According to maceral constituent of organic matter,hydrocarbon generating potential,sedimentary facies,geochemistry facies and atomic ratio of kerogen element etc.,the organic facies is divided into four types:Lipid hydrogen rich face,Lipid vitrum hydrogen rich face,Lipid vitrum hydrogen poor face and vitrinite hydrogen poor face;Based on the above mentioned data,organic facies maps of Eocene Series,Oligocene Series and Miocene Series were drawn.This research have been taking an important role in petroleum exploration and development in Xihu Sag.
