| Petroleum exploration and exploitation is an important part of the petroleum industry. It directly decides the oil output. In the process of oil exploration and exploitation, a great deal of three dimensional seismic data can be collected.According to the three dimensional seismic data characteristic, in the article some essential technology are studied, such as magnanimous data read-write processing, data management, fast and accurate algorithms, high-level visualization capabilities to graphics which includes two dimension and three dimension, dimensional camber stratal surface analysis and application, spatial data volume analysis and so on. To resolve these issues is major research goal. A new data structure and control methods for three-dimensional data object is developed to accelerate visiting rate. The technology of profiles, time-slice, and data sub-volume roaming in three dimensional seismic data has achieved. With this technology, the new methods that interactive stratal surface interpretation guided by profiles and data sub-volume and that interactive fault interpretation guided by profiles are realized. By using of three dimensional volume visualization advantages, explorer may improve effect of vision and highlight unusual aim through adjusting color, transparence, orientation of light. Explorer not only can observe exterior characteristics of data volume, but also can clairvoyance interior structure. Explorer places himself in a brand-new three dimensional environment, and controls explanation process with agile interactive technology. thereby explorer greatly enhance the efficiency and accuracy of interpretation.Coherence cube can clearly reveal faults and stratal characters as compared with conventional seismic cube. According to coherence technology of three dimensional seismic data ,a new method for auto fault interpretation in complicated structural environment was proposed in this paper. A selective filter was applied to the coherency cube, and the result was... |
