Embodiment Construction

[0027] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0028] like figure 1 As shown, the Gaussian ray tracing scanning method based on seismic data of the present invention comprises the following steps:

[0029] (1) Obtain tracking parameters from the seismic data collected in the field (also known as shot data, shot data, seismic records.), the tracking parameters include: amplitude factor, sampling interval, sampling number, wavelet frequency, scanning Interval, scan transverse start angle, scan longitudinal start angle, scan transverse end angle, scan longitudinal end angle, shot depth, ray tracing radius;

[0030] (2) According to the location of each discrete point of the seismic data, calculate the position of the exit point: obtain the coordinate value of the current discrete point of the seismic data (horizontal direction x, vertical direction z) and the coordinate value of each coordinate point from the seismi...

Abstract

The invention provides a Gaussian ray tracing scanning method based on seismic data, and belongs to the field of computer exploration. The method is based on seismic data and a trial firing method principle, data of Gaussian ray tracing scanning are stored through a ray tree, attribute data can be stored, and the relation between rays can be stored. According to the method, the ray tree structure body based on the seismic data can be obtained, metadata in Gaussian ray tracing calculation is stored through the ray tree, attribute (parameter) data are stored, the relation between rays is stored, use of a forward modeling and migration method based on the ray tracing result in the later period is facilitated, and the method has good application prospects. A ray tree and various attribute data of each ray thereof are provided for forward modeling and offset based on Gaussian rays.

Description

technical field [0001] The invention belongs to the field of computer exploration, in particular to a Gaussian ray tracing scanning method based on seismic data. Background technique [0002] At present, Gaussian ray-tracing methods include shooting method, bending method, etc. Among these methods, shooting method is a method for solving initial value problems, and is widely used in forward modeling and migration of seismic exploration. From the algorithm theory, this method has been very mature. However, in the implementation of this algorithm, there are basically no public references to the method of creating ray trees based on Gaussian ray tracing scans. [0003] The traditional calculation method is to calculate various attribute (parameter) data of ray tracing based on each shot, and save them as files respectively, but cannot save the relationship between rays. Contents of the invention [0004] The purpose of the present invention is to solve the problems existing...
