    • Abstract
  • Purpose : To analyses the 3-D seismic data with visualization, and see the geologic phenomenon and regularity directly hidden in the data. Methods : Using a particle model to show a reflection wavelet, all the particles from the same bed will coincide to a reflection surface. In order to improve display velocity, transform the seismic data to a 3-D two-valued image, trace the 3-D connected zone with ordered cross algorithm, thin the zone to get the coordinate of the reflection surface. Observe directly the stratigraphic structure by drawing the stereoscopic image of reflection surfaces in virtual reality system. Results : The 3-D shape of reflection surfaces and the extension of the faults is observed by fact experiment. The stereoscopic image can reveal more profoundly the complex geologic phenomenon. Conclusion : The method is efficient. Only visualization in virtual reality can directly observe the underground scene, and may realize 3-D interpretation of 3-D seismic data really.
