Problems solved by technology

[0017] In order to solve the above technical problems, the present invention proposes a multi-attribute seismic data visualization method based on continuous parallel coordinates. For multi-attribute seismic data, the idea of ​​continuous parallel coordinates is used to draw a density map between parallel coordinates according to multi-attribute data, instead of The broken-line graph drawn in the past solves the problem of repeated drawing. Based on this, the target characteristic parameters are obtained through multi-dimensional data correlation analysis and human-computer interaction, and they are used to guide the fusion parameter setting of multi-attribute fusion drawing, forming a A complete set of visual analysis process

Embodiment Construction

[0046] In order to facilitate those skilled in the art to understand the technical content of the present invention, the content of the present invention will be further explained below in conjunction with the accompanying drawings.

[0047]The present invention firstly combines two-by-two multi-attribute seismic data, and then obtains the density map of the attribute of many pairs of two-two combinations in the data domain; secondly, in order to obtain the density of each point in the parallel coordinate domain of each two attributes, the two On the data field density map of one attribute, the line corresponding to this point is integrated to obtain the density map in the continuous parallel coordinate field composed of multiple attributes; finally, through human-computer interaction means, through the box selection operation on the parallel coordinate field , to guide the setting of fusion parameters for fusion volume rendering, and complete the final fusion volume rendering....

Abstract

The invention discloses a multi-attribute seismic data visualization method based on a continuous parallel coordinate. The method comprises the following steps: adopting an octree hierarchical method for accelerating uniform areas, reducing the drawing times of the uniform areas and increasing the algorithm efficiency; drawing a density map of a parallel coordinate domain and showing incidence relation between multi-attributes; designing a two and three-dimensional linked visual analysis interaction platform, eliminating a complex operation of manually setting a transmission function, screening and selecting the interesting areas on the continuous parallel coordinate and automatically setting the transmission function of each attribute data, thereby prominently showing the selected interesting areas in the result image drawn on the fusion.

Description

technical field [0001] The invention relates to the field of seismic data processing, in particular to a multi-attribute seismic data visualization technology. Background technique [0002] Seismic attribute is an attribute for the quantitative division of seismic data regions of interest. Since it was proposed in the early 1970s, it has become an important part of seismic interpretation projects. Today, more than 100 different These properties are widely used in the interpretation of geological structure, stratigraphy and demonstration / porofluidity. The development of seismic attributes is closely related to the advancement of computer technology. [0003] Nowadays, the technology of oil exploration points is becoming more and more mature, and the terrain complexity that geophysical prospectors can test and survey is getting higher and higher, but there are still many hidden oil and gas that cannot be explored by relying on conventional technical means. That is, surveying...
