摘要
本文从沉积相、岩性和测井相入手，分析了下白垩统登娄库组三段岩性发育及相类型，并划分了层序旋回，识别出各旋回体系域归属。并对上述划分用Ｆｉｓｃｈｅｒ点图进行检验，证明上述分析是合理的。同时，本文指出，Ｆｉｓｃｈｅｒ点图在旋回识别上有独到之处。
The third member of the Denglouku Formation is a prospect area for the oil and gas resources in the Xujiaweizi subsidence, Daqing, northeastern China. In this paper, the lithology and sedimentary facies are discussed, and sequence stratigraphic cycles and their systems tracts am discriminated on the basis of sedimentary facies, lithology and well logs. The classification has been verified by using Fischer's plots, which may be a potential tool for sequence analysis.
