RESEARCH OF AUTOMATIC MODELLING ON 3D DIGITAL STRATIGRAPHIC FRAMEWORK BASED ON BORING DATA

The research of automatic modelling on three-dimension (3D) digital stratigraphic framework is a preliminary approach to the 3D automatic modelling of geologic bodies.Based on doring data, the automatic modelling was divided into two processes independent each other in the perpendicular and parallel directions of stratigraphic interfaces by numerical and non-numerical calculation such as digitization, trigonometric division and stratigraphic correlation.At first, linear interpolation was used to model stratigraphic framework cells automatically.Then, the models of framework cells were conformed according to numerical relations among them so as to form stratigraphic framework bodies.
