Embodiment Construction

[0053]In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0054] First of all, it should be explained that the wave travel time acquisition method and device provided by the embodiments of the present invention can not only be used to obtain the travel time of seismic waves, but also can be used to obtain the travel time of other forms of waves, such as light waves, radar waves, and sound waves. For ease...

Abstract

The invention discloses a travel time obtaining method of a wave. The method includes: obtaining a horizontal distance from a first point to a second point; inputting a horizontal distance into a first preset model to obtain a radial parameter between a first point and a second point; inputting the radial parameter into a second preset model to obtain the travel time of the wave from the first point to the second point; wherein the first preset model is obtained by at least one Shanks transformation of the propagation distance polynomial of the wave, and/or the second preset model is obtainedby at least on Shanks transformation of the propagation time polynomial. Because any one of the first preset model and the second preset model is obtained by at least one Shanks transformation according to the corresponding polynomial, the first preset model and/or the second preset model obtained through the Shanks transformation have higher precision and convergence speed, As a result, the accuracy of the results obtained is higher than that calculated according to the original calculation formula. The calculation time is shorter and the requirements of geological exploration can be met.

Description

[0001] This application claims the priority of the Chinese patent application submitted to the China Patent Office on October 31, 2017, with the application number 201711047776.9, and the title of the invention is "wave travel time acquisition method and device, imaging method and device", the entire content of which is incorporated by reference incorporated in this application. technical field [0002] The invention relates to the technical field of geological exploration, in particular to a method and device for acquiring wave travel time, and an imaging method and device. Background technique [0003] The travel time of a wave refers to the time it takes for the wave to travel from the source to the observation point. For example, seismic wave surveying and mapping involved in the field of geological prospecting, the travel time of seismic waves refers to the time required for seismic waves to propagate from the shot point (ie source point) to the imaging point (ie observ...
