Abstract: Three-dimensional geological model plays an important role in geological prospecting and resource evaluation, and its quality determines the application potential and effect of the model.This paper reviews the research progress of 3D geological model quality evaluation at home and abroad, and systematically expounds the factors that affect the quality of 3D geological model, including the complexity of modeling geological objects, the accuracy and quality of modeling data sources, the methods of 3D geological modeling, and the expert knowledge of modeling personnel.At the same time, the paper analyzes the principle, advantages and disadvantages of the main methods of quality evaluation of 3D geological models, and holds that the quality evaluation of 3D geological models has gradually entered the era of quantitative evaluation from qualitative evaluation.Finally, this paper summarizes the problems existing in the research of 3D geological model quality assessment methods, and discusses its future development trend.
