Magnanimity earthquake three-dimensional visual display method

Abstract

The invention provides a massive seismic three-dimensional visualization display method, comprising the following steps: the seismic data managed by the software Geoframe and Landmark is acquired in real time; a virtual oilfield scene is built by true geometric information data of the oilfield; according to the data read in Step A, the massive data is drawn in the scene of Step B; furthermore, the visualization operation of the data in the scene is carried out; a texture drawing method provided by OpenGL is adopted and the advantages of the display card of the current mainstream workstation on the display bandwidth are fully used for carrying out high-speed drawing. The color range of the acquired seismic data correspondingly in the color table is determined and the acquired color data is loaded into the texture cache of the OpenGL and is used in the drawing. The method can synchronously display various data such as seabed, ground surface, platform and the like, can effectively display various data such as the seismic data, well data and seabed situation and the like in the process of exploration, development and production so as to get rid of the technical monopolization of foreign software.

Description

technical field

[0001] The invention relates to a three-dimensional visualization display method. In particular, it relates to a massive seismic three-dimensional visualization display method that displays massive seismic data volumes through a three-dimensional visualization method, and realizes massive seismic data from multiple work areas in the same scene in a three-dimensional environment. Background technique

[0002] The three-dimensional visualization display in virtual reality technology has been widely used in all aspects of the oil industry by some large oil companies in the world. played an important role. However, the existing 3D visualization software can only display seismic data volumes that are smaller than the current machine memory. However, the amount of seismic data in each work area of ​​an oil field can reach tens of GB, and some even reach 200 GB. Obviously, the development speed of computer hardware can no longer meet the requirements of large data ...
