The accuracy of 3 D geological modeling(A3 DGM)on geological application, such as spatial analysis, resources calculation and numerical simulation, is important in the progress of geological survey. There is practical significance to analyze the influencing factors of accuracy in the process of 3 D geological modeling and quality control of 3 D model. Through the analysis of characteristics of every step in the workflow of 3 D geological modeling, six factors influence the quality of 3 D geological modeling in the following six aspects: data sources, interpolation method, modeling method, complex and randomness of geological bodies, computer science and modeling experts. The study discussed the quality control method of 3 D structural model(SM)and 3 D property model, and finally forecasted the direction of regional modeling technique development in the future based on the accuracy control of 3 D geological modeling. This paper provides an important enlightenment for modeling in the process of quality control.
