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, Guangzhou Marine Geological Survey upgraded and upgraded the original source of the “Bao Bao” ship to an array-variable BOLT source system. With the success of the renovation project, the vessel has become a multi-purpose seismic survey ship with high-resolution, conventional and low-frequency deep-water seismic exploration. This paper introduces the basic working principle of the seismic source and the distribution, waveform and spectrum of the three arrays.
