It is dynamic open gas release channel (Chen Xianzhan, Liu Hao, Fu Delian etc., the Primary Study of air gun source structure, geophysical equipment, 2009,
19(supplementary issue), 7-14), such as BOLT air gun (discussion of Ma Yuejun, the BOLT accident analysis of air gun source work system and application, object
It visits and equips, 2002,12(2), 117-120) and, air gun is caused to make under the high concentration of sediment adverse circumstances such as marine corrosion environment and rivers
It is broken down with easy, the work such as need to largely be safeguarded, be maintained, overhauled.Furthermore the air gun system to be worked using such mode
System, is limited, generally within 30MPa, seismic source energy density is difficult further to mention operating pressure by gas pressurized device
It is high.Need to be using air-gun array mode in order to improve excitation energy, but this mode has synchronous or timing requirements again, air gun is synchronous
Error determines that the synchronous characterization of general air gun is in the world: in common seismic exploration, air gun is same according to specific test condition
Accidentally absolute value of the difference is less than or equal to 1ms to step, and when carrying out high resolution exploration, synchronous error is 0.3~0.5ms(Zhou Baohua, Liu
Prestige north, the development of air gun source and uses analysis (under), geophysical equipment, 1998,82,1-10).Existing air gun relies on mechanical movement
Discharge high pressure gas, thus it is synchronous or time sequence precision further increase it is also highly difficult.Existing air gun source work when be both needed to from
Pressure charging system connects high-pressure gas pipeline to air gun, is limited by length of pipe, working depth is difficult to further increase, at present
Generally less than 10m, is unable to cloth and is put into seabed to be excited to improve detection accuracy.Importantly, air gun source system at
This height, expensive, marine air gun focus need to be equipped with the ancillary equipments such as high-power air compressor system, only high-power air compressor system
With regard to needing up to ten million members.
