摘　　要：利用薄片、X衍射、微量元素、孢粉及有机地球化学等分析手段对王46井岩心进行了岩性、古生物及地球化学等相标志研究,认为该段暗色泥岩为湖盆近边缘相产物,沉积期气候暖热湿润,水质微咸淡水。The hydrocarbon source rock of Kongdian formation is definitely validated on oil-to-source correlation between oil produced in well Wanggul and dark mudstone drilled in Wang 46. It is absolutely necessary to study the sedimentary environment of the dark mudstone for the purpose of realizing the potential scale and capacity and determining appropriate well site. Using thin section, X-ray and ICP-AES analysis, identification of sporopollen and organic geochemistry analysis, the dark mudstone of the second member of Kongdian formation from well Wang 46 is researched on petrology, paleontology, geochemistry and other facies indicators to form in deoxidized lacustrine environment with light salted-fresh water, wet and warm climate.
