Hydrocarbon distribution pattern and logging identification in lacustrine fine-grained sedimentary rocks of the Permian Lucaogou Formation from the Santanghu basin

A series of qualitative descriptions and quantitative analyses was used to determine the lithofacies characteristics and hydrocarbon distribution pattern of Lucaogou Formation fine-grained sedimentary rocks in the Santanghu Basin. The qualitative descriptions include core description, petrographic thin section observation, fluorescence observation, cathode luminescence observation and scanning electron microscope (SEM) observation. The...
