A new method of shale oil facies element logging evaluation and its application in Dongying Sag by GUAN Qianqian,JIANG Long,CHENG Ziyan,ZHANG Diandong,WANG Yunhe,ZHANG Fan

“…Utilizing the “three terminal elements and four elements” shale lithofacies partitioning scheme as a guiding principle, this research selects responsive characteristics of different lithofacies logging and sensitive parameter logging curves to develop an appropriate shale oil logging lithofacies partitioning method. The approach combines stratification, clustering through Agglomerative Hierarchical Clustering（AHC）, Fisher discriminant analysis, wavelet frequency extraction, and genetic optimization neural networks to discern the rock composition, sedimentary structure, rock texture, and organic matter content of different lithofacies. …”
