“海豹”系列浅水气枪震源船的研制与应用

Development of Haibao series shallow water airgun seismic source vessel and its application

空气枪是海上地震勘探区域的主要激发震源,广泛使用于包括沿海带和内陆湖的浅水域,以及大陆架和深海探区的海上勘探。因此,承载气枪的气枪震源船在海上地震勘探中成为了重点设备,并在海洋勘探中发挥着重要作用。文章提出了为了满足地震激发的基本技术要求而设计的浅水气枪震源船,需要考虑的是气枪阵列几何尺寸、气枪类型、气枪激发间隔,以及船体和船上设备的抗震设计和吃水深度。介绍了海豹系列浅水气枪震源船的特点、野外应用和优缺点。论述目前正在建造中采用了已经获得专利申请号技术的海豹五号气枪震源船的特点和新型设计。

The airgun is a primary seismic source in the marine seismic exploration,which exploration areas includes shallow water in coastal zone as well as inland lake,offshore exploration on the continental shelf and abysmal area.Therefore,the airgun source vessel has become a key component and played an important role in marine seismic exploration.This paper presents the airgun array geometry,array type,airgun firing interval,the equipment aseismic design and draught must be considered in the design of a shallow water airgun vessel.This paper introduces the features,field application as well as the advantages and disadvantages of Haibao series shallow water seismic source vessel,and expounds the new style design and features of Haibao5 airgun vessel with patent pending construction.
