Sled-type seismic source module

Abstract

The invention provides a sled-type seismic source module, and the module comprises a sled block support of a rectangular structure, two floating bodies which are disposed on the upper surface of the sled block support through floating body fixing buckles, a seismic cable wet end big head, three groups of air gun seismic sources, a plurality of chains, a cable, and an air cable. The seismic cable wet end big head is fixedly disposed on the upper surface of the sled block support, and is arranged in the same length direction of the two floating bodies. The cable and the air cable are respectively connected with the seismic cable wet end big head and each group of air gun seismic sources. The three groups of air gun seismic sources are all disposed in the frame of the sled block support, and are respectively fixedly connected with the frame of the sled block support. The three groups of air gun seismic sources are sequentially arranged in the length direction of the sled block support. The module provided by the invention is simple in overall structure, is small in number of spare parts, does not need any special storage device, is excellent in maximum output energy, can provide the energy output similar to a point seismic source, and is suitable for high-resolution exploration.

Description

technical field [0001] The invention relates to the field of marine seismic survey equipment, in particular to a skid-type seismic source module. Background technique [0002] Marine seismic survey ships, like other professional ships, are special ships specially designed and manufactured for specific operations. Therefore, it is simple and easy to use common seismic source modules on marine seismic exploration ships due to their innate space pipeline and other design advantages. [0003] With the improvement of the comprehensive capabilities of marine scientific research ships by the Chinese government, more and more marine scientific research ships have taken up the task of seismic exploration. However, the rear deck of non-professional seismic exploration ships is narrow, with limited relative space and no buffering conditions. , or the structure of the ship is not conducive to the retractable construction of the source module and many other aspects hinder the seismic su...

[0003] With the improvement of the comprehensive capabilities of marine scientific research ships by the Chinese government, more and more marine scientific research ships have taken up the task of seismic exploration. However, the rear deck of non-professional seismic exploration ships is narrow, with limited relative space and no buffering conditions. , or the structure of the ship is not conducive to the retractable construction of the source module and many other aspects hinder the seismic survey task to a certain extent, so it is necessary to design a new source module to solve the above problems
