新型浅海气枪震源阵列收放技术

New Technology for Deploying and Retrieving Shallow Water Airgun Array

文章分析了侧吊式、拖曳式气枪震源阵列收放技术的优缺点,从克服缺点的角度介绍了一种新型浅海气枪震源阵列收放技术,即混合式气枪震源阵列收放技术。该技术通过辅助收揽臂,实现了侧吊式与侧后拖式模式间的无缝式全机械变换,降低了劳动强度,提高了工作效率,在浅海地震勘探领域具有一定的推广价值。

In general,only a method could be used for deploying and retrieving airgun array in a shallow source boat.There are two methods for this purpose: side-hung and tow-rear airgun array deploying and retrieving.This paper discusses the advantages and disadvantages of the two methods,then proposes a new technology (the auxiliary arm for retrieving cables) for deploying and retrieving airgun array.The new technology could help complete mechanical transforms between side-hung and tow-rear with seamless type,and improve shallow water airgun shooting efficiency.It could be applied in the shallow seismic exploration domain.
