The Application Of Virtual Reality Visualization Of 3d Seismic Data In The Study

The traditional seismic data interpretation method, which shows seismic data sets by displaying the planar image of seismic section and horizontal slice, is not visual and intuitionistic enough. With development of three dimension display device, the three dimension interpretation of seismic data is more needed. By Combining the Virtual Reality technique and visualization technique, it will develop a Virtual Reality display system of the geology-constructed-model by which we can get the distributing information, location information and structure information of stratum, faultage and well vividly.This article includes pretreatment of stratum data, faultage data and well data, modeling process and stereoscopic display and interact operation in Virtual Reality system. It introduces the usage of gridding in stratum data pretreatment, the usage of triangulation in stratum modeling process, the usage of construction of 3D objects from serial 2D contours in faultage modeling process, the smoothness of geology-constructed-model and stereoscopic display with LCD stereoscopic glasses .The experiment with the data from DaQing Oil Base proves that the Virtual Reality display system of geology-constructed-model can represent the geology structure more intuitionistic and vividly.
