Abstract：The primary objective of geophysical research is the exploration of underground structures and to serve as a valuable tool for geological interpretation.The formation structure and properties can be determined by analyzing the physical properties of the underground medium reflected by geophysical data,such as density,velo-city,magnetic susceptibility,resistivity,and more.Given the numerous solutions of a single geophysical method,comprehensive geophysical interpretation is currently a feasible and effective approach.This study explores litho-logy prediction,providing a summary of the basic principles and steps of comprehensive geophysical interpretation methods for lithology prediction.Additionally,it outlines the main technical methods of comprehensive lithology prediction involving two kinds of technical routes:knowledge-driven and data-driven.The knowledge-driven meth-od uses prior information.It is simple,direct,and easy to understand,but has weak adaptability to the complexity and high dimension data.The data-driven method employs a mathematical statistics strategy to explore the relation-ship between data and has a robust capacity to adapt to complex scenarios.In solving practical problems,the super-vised machine learning method,based on sufficient rock physical properties research,not only incorporates prior knowledge but also maximizes its internal data exploration ability.It can enhance the accuracy of lithology predic-tion and interpretation,better establish the corresponding relationship between geophysical and geological informa-tion,and support the exploration needs of resources and energy.
