Abstract: This paper presents a 3D complex geological entity modeling method based on line-frame model, designed to accurately express the spatial geometrical shape of every element of a complex geological entity and their mutual relationship. This method enables the fast construction of a fault model, stratum model, or complex geological entity model in the case of fault interleaving. Proved in modeling practice, this method is an accurate and effective method for constructing a 3D complex geological entity and it can adapt to constructing 3D geological entity model in the case of familiar complex geological conditions.
