Prediction of Element and Clay Mineral Content in Lacustrine Mudstone Using Logging Data:an example from Dongying Depression

摘要

1 Introduction Clay minerals are main components in shale and mudstone,different components including montmorillonite,Illite/montmorillonite(I-S)mixed layer,illite and chlorite in shale have different gas sorption capacity.Therefore,further analysis and evaluation on the components of clay minerals is necessary for evaluating the mechanism of shale gas existence.Clay minerals
