气体震源或气枪是海洋石油勘探的一种方便和有效的震源。 近年来在海洋地震勘探中人们作了很多努力,用非炸药能源代替炸药,出现了不少新方法,如电火花发生器,气体脉冲发生器等。气体脉冲发生器通常称为气体震源或“气枪”。它是利用在大约150大气压力下容纳一定量空气的气室,使用快速启动的电磁阀门开启,气室的压缩空气向周围水中突然释放,空气的这种突然扩张便产生了地震信 A gas source or air gun is a convenient and effective source for offshore oil exploration. In recent years, many efforts have been made in marine seismic exploration, and non-explosive energy sources have been used to replace explosives. Many new methods have emerged, such as electric spark generators and gas pulse generators. Gas pulse generators are commonly referred to as gas sources or “air guns.” It is the use of a volume of air at about 150 at atmospheric pressure chamber, the use of quick-start solenoid valve open, the air chamber of the compressed air suddenly released into the surrounding water, the sudden expansion of air will have a seismic letter
