Embodiment Construction

[0063]In order to make the purpose, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described The implementations are only some of the implementations of the present invention, but not all of them. Based on the implementation manners in the present invention, all other implementation manners obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present invention.

[0064] The prior art is a combined method of constructing airgun sources from the standpoint of total capacity. Because the application effect of the airgun source is not only limited by the total capacity and combination of the airgun, but also related to the frequency of excitation, more low-frequency informati...

Abstract

The invention relates to the technical field of air gun source, and discloses an air gun source setting method and device and a machine readable storage medium. The method comprises the steps of obtaining a target frequency of a target layer; determining the sinking depth of the air gun source according to the target frequency; determining the total capacity of the air gun source according to thesinking depth; and determining the arrangement combination of the air gun source according to the target frequency and the total capacity. The air gun source is set according to the combination of thesinking depth and the capacity, the application effect is good, and the method has the advantages of high signal-to-noise ratio of seismic data, smooth frequency spectrum, good source directivity andthe like.

Description

technical field [0001] The present invention relates to the technical field of airgun seismic sources, in particular to an airgun seismic source method, device and machine-readable storage medium. Background technique [0002] The airgun source has become an artificial source with the advantages of environmental protection, good repeatability, economy and practicality, and has been widely used in marine seismic exploration. Due to the different seismic and geophysical conditions in the exploration blocks and the different exploration target layers, the requirements for the air gun source are also different. In order to obtain good marine seismic exploration data, it is first necessary to design a high-performance seismic source that meets the requirements of seismic exploration. [0003] What is provided in the prior art is a combined method of constructing an airgun seismic source from the perspective of total capacity. This method is too simple, and this method is limited...
