Waveform variable-area seismic profile display method and device

Abstract

The invention discloses a waveform variable-area seismic profile display method and device. The method comprises the following steps of: determining a transverse drawing ratio according to the transverse logic resolution of the screen of display equipment and the number of seismic channels per inch of the display equipment, drawing an initial seismic profile in a generated temporary grating graph when the transverse drawing ratio is not greater than a transverse drawing ratio threshold, and displaying the temporary grating graph containing the initial seismic profile in a drawing area of the display equipment to obtain a waveform variable-area seismic profile. According to the method, the transverse drawing ratio is compared with the transverse drawing ratio threshold, and when the transverse drawing ratio is not greater than the transverse drawing ratio threshold, the initial seismic profile is drawn in the generated temporary grating graph with the transverse drawing ratio being the transverse drawing ratio threshold, so that the waveform variable-area seismic profile is obtained, abnormal phenomena such as black screen in waveform variable-area seismic profile display can be eliminated, meanwhile, the false frequency phenomenon generated by channel extraction processing is avoided, and the waveform variable-area seismic profile display effect is improved.

Description

technical field [0001] The invention relates to the technical field of seismic exploration, in particular to a method and device for displaying a wave-variable area seismic section. Background technique [0002] This section is intended to provide a background or context to embodiments of the invention that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] Seismic data display, especially stacking section display, is a basic and important module in seismic data processing and interpretation software systems. Seismic data needs to be displayed in the form of images with the help of computer technology, providing a visual judgment basis for seismic and geological personnel. An intuitive and correct seismic display can better assist geological researchers to make accurate analysis of seismic data and draw correct conclusions, which has important practical significance for oil and gas exploration, geologi...

Problems solved by technology

[0006] However, when drawing a large-scale wave-variable-area seismic section, due to the limitation of computer screen resolution, when the distance between two adjacent corrugated lines is less than one pixel after zooming out to a certain extent, the conventional wave-form variable-area section will be There is an abnormal phenomenon that the entire screen is completely black

Although this method is simple to implement, it will generate false frequencies, which will interfere with the interpreters' grasp of the overall geological conditions
