Lithology identification method of thick sand mudstone formation logging in Huagang Formation,N Structure,Xihu Sag
The West Lake Depression is located in the East China Sea,where drilling and coring are relatively difficult,with limited coring data and rough cuttings logging data.In order to obtain more precise formation lithology,a supervised machine learning method based on unsupervised machine learning is adopted for lithology identification.The results show that the method has a lithology recognition rate of over 95%for the strata in the study area,and can quickly and accurately identify the lithology of the target layer.
