Problems solved by technology

However, with the development of survey technology and the development of subsequent processing technology, a single attribute can no longer explain seismic information well.
[0012] However, for the processing methods of multiple seismic attributes, there is no effective algorithm for calculating and merging various seismic attributes.
The fusion during rendering has only been realized in 2D section display, and there is no good algorithm in 3D seismic volume rendering

Embodiment Construction

[0038] Before introducing the scheme of the present invention, introduce several concepts:

[0039]SEGY: SEGY (Society of Exploration Geophysicists Y format) seismic data is one of the general format standards for many tape-type seismic data developed by the American SEG (Society of Exploration Geophysicists) Association in the 1970s to facilitate the exchange and sharing of seismic data. It is organized in units of seismic channels and stores seismic channel data channel by channel. At present, SEGY seismic data files have become the most commonly used data recording carrier in outdoor data acquisition in the oil and gas exploration industry.

[0040] Transfer function: The transfer function mainly maps the data values ​​of the three-dimensional data field to optical properties, such as opacity, color values, etc., which determine the imaging quality of volume rendering. Therefore, the design of the transfer function is a key process in the volume rendering process.

Abstract

The invention discloses a multi-seismic attribute fusion texture mapping volume rendering method based on opacity weighting. The transfer function of each attribute data is used to obtain the mapping color value and opacity of voxel, and then the opacity of each voxel is determined. The proportion of the color value of the seismic attribute component; after opacity weighting, the new color value is finally synthesized, and then drawn in a two-dimensional texture volume rendering method. The method of the present invention realizes multiple seismic attributes while display, which brings convenience to earthquake interpreters.

Description

technical field [0001] The invention relates to a multi-seismic attribute fusion texture mapping volume rendering method based on opacity weighting. Background technique [0002] With the application and development of various technologies in oilfield seismic exploration, exploration workers have higher and higher requirements for seismic results. In the face of increasingly complex and hidden oil reservoir conditions, in order to improve the success rate of drilling, it is necessary for exploration workers Provide a brand-new geological structure form and its attribute characteristics. The emergence of scientific computing visualization technology provides mature technical support for the realization of this idea. Scientific computing visualization technology is applied to seismic data, resulting in seismic visualization technology. Seismic visualization can not only improve the efficiency, accuracy and completeness of seismic interpretation, but it is also easy to unders...
