Palynofacies and Oil Potential of Carbonate Rocks of Tertiary Hetaoyuan Formation in Biyang Depression

摘要: 孢粉相是反映一定沉积物以及成岩作用环境的显微沉积有机质组合。对我国河南泌阳凹陷下第三系核桃园组核三上段至核二段湖相碳酸盐岩系孢粉相进行了详细研究。基于有机质组分的鉴定和统计将碳酸盐岩系划分为五个孢粉相带;并利用孢粉相结合有机质成熟度地化指标,对其生油潜能进行了评价。Abstract: Palynofacies is a particular sedimentary organic matter association that can reflect sedimentation and lithogenesis environment. The palynofacies of carbonate rocks of Tertiary Hetaoyuan formation have been studied in detail. Based on the identification and statistics of the organic matter, The carbonate rock series may be divided into five palynofacies zones. Using palynofacies combining with geochemicalindices of organic maturation, the oil potential of these strata has been evaluated.
