Abstract

The invention provides a high-pressure gas cylinder group for an earthquake acquisition ship. The high-pressure gas cylinder group for the earthquake acquisition ship is characterized by comprising aplurality of gas cylinders and a gas cylinder fixing frame, wherein the plurality of gas cylinders are placed horizontally; the gas cylinder fixing frame comprises at least two layers of supporting frames; each layer of the supporting frame is arranged horizontally; gas cylinder placing bases are arranged on the supporting frames; and the gas cylinders are placed on the gas cylinder placing basesand fixed on the gas cylinder placing bases through U-shaped buckles. The air flow and the air pressure of the compressed air output by the gas source are unstable, and the compressed air output by the gas source is buffered by the gas cylinder group provided by the invention and is finally output under constant and stable air pressure.

Description

technical field [0001] The invention relates to the technical field of offshore operations, in particular to a high-pressure gas cylinder set for a seismic acquisition ship. Background technique [0002] In water, seismic waves can be detected by the pressure changes they create. In the prior art, large-volume airgun seismic sources are used in seismic exploration of water areas, engineering geological surveys, and research on deep-sea crustal structures. An airgun source is a source in which compressed air is released suddenly into the water, producing short, high-energy seismic pulses. During the detection process, a seismic source is provided on the seismic acquisition ship to provide compressed air for the airgun seismic source. However, the compressed air flow and air pressure of the original origin are both unstable, resulting in the instability of the seismic pulse source emitted by the air gun source, which affects the exploration results.
