Abstract

The invention discloses a pneumatic gun focus vessel, comprising a main deck and a second-floor platform. The main deck is provided with at least one main deck sliding rail and at least one main deck towing mechanism. The main deck towing mechanisms are arranged on the sides, close to a bow, of the main deck sliding rails; the main deck towing mechanisms are used for deploying and retracting pneumatic gun assemblies through towing seismic cables; the second-floor platform is positioned above a main deck and the main deck sliding rails; the second-floor platform is provided with at least one second-floor platform sliding rail and at least one second-floor platform towing mechanism; the second-floor platform sliding rails are used for allowing pneumatic gun assemblies to slide in the length direction; the second-floor platform towing mechanisms are arranged on the sides, close to the bow, of the second-floor platform sliding rails; the second-floor platform towing mechanisms are used for deploying and retracting pneumatic gun assemblies through towing seismic cables; the second-floor platform sliding rail is parallel to the other the second-floor platform sliding rail; and the projections of the second-floor platform sliding rails and the projections of the main deck sliding rails on the main deck in the vertical direction are staggered.

Description

technical field [0001] The invention relates to the technical field of geophysical exploration, in particular to an air gun seismic source ship used for marine geophysical exploration. Background technique [0002] In offshore petroleum geophysical exploration and acquisition operations, the function of the air gun source ship is to carry the air gun array, and generate artificial seismic waves through air gun excitation. Wherein, the air gun sub-array is an aggregate composed of multiple air guns arranged linearly on a gun bar or hanger plate, and the air gun array is composed of multiple air gun sub-arrays. The strength requirement of artificial seismic waves for physical exploration and acquisition determines the size of the air gun array. At the same time, the size of the air gun array is also limited by the net area of ​​the main deck of the source ship. [0003] The existing air gun source ships of this type all place the air gun arrays on the same deck plane, and the...
