摘要

2001年,广州海洋地质调查局对“探宝号”船原有震源更新升级为阵列可变的BOLT震源系统。随着更新改造工程的成功,该船已成为具备承担高分辨率、常规、低频深水油气地震勘探的多功能地震调查船。本文介绍了地震勘探震源的基本工作原理以及三种阵列的分布、波形、频谱等特性。
In 2001,GMGS upgraded the seismic source on vessel“Tan Bao Hao”to a flexible air gun array which was designed and manufactured by Bolt Technology Corporation.After the successful completion of upgrade project,the vessel itself is now able to serve as a multi-purpose seismic survey vessel for Hi-resolution and conventional seismic surveys as well as deep crustal geological survey.This article gives a brief introduction of operational theory of the energy source on the vessel and is accompanied with the geometry,Far-field signature and spectrum of the three different arrays which are comprised from a standard array by using interchangeable air chambers on the vessel for various prospective purpose.
