The classification of shales plays an important role in drilling and drilling fluid engineering,while the study of the classification of shales must start with the analyses of the component and structure and physical-chemical properties of the shales.This paper introduces various method of classification of shales presented and the advantages and disadvantages are analyzed.A simple classification was provided based on the analysis in this paper.This classification method takes into account the comprehensive properties of shales and each property can be quantified.This paper also introduces a method of shales classification called BP neural network method.The paper says that based on the research on the hydration mechanism of shales,less parameters may be needed in the future to classify the shales,and to guide the establishment and implement of drilling and drilling fluid operation.
