DESIGN OF 3-DIMENSIONAL VISUALIZATION DATA MODEL FOR MARINE GEOLOGY

With the deepening of marine geology survey, marine geological data is getting more diversified. Marine geological maps upon seismic interpretation are important source of information for study of marine geological structures so as to serve offshore oil and gas exploration and development. The compilation of marine geological maps follows the procedure of data preprocessing, stratigraphic boundaries building and adding fault constraints lines. An integrated data model of 3-Dimensional visualization is developed by the authors according to the needs in 3-Dimensional visualization display. Based on an integrated data model, a marine geology 3-Dimensional visualization software (MG3D) is developed using the Open Inventor, a 3-Dimensional graphic software development kit, and the C # development language on.Net platform. Integrated display and interactive functions are thus realized among stratigraphic data, fault data and well data. The integrated data model of 3-Dimensional visualization has certain research value and is effective in serving the geological researchers.
