摘要
在使用气枪震源作为激发源的勘探区域,使用Bigshot、GCSLink2000和428 XL海缆三大系统联机是较为常用的作业方式。GCSLink2000主、从同步器通过电台保持两者之间的严格同步。但当两者距离过远时,信号会因路径传输中的损耗而变弱,导致频繁废炮现象的发生,严重影响了气枪船的作业效率。本文介绍了一种水上地震勘探的有线放炮技术。将原先置于仪器车上的GCSLink2000主同步器和辅助道通过428 XL交叉站连接到距离气枪船较近的水中排列上,以缩短主、从同步器之间的电台通讯距离,提高通讯效果,使得主仪器无需频繁搬家也能持续生产,从而提高水上作业效率。
The use of air gun as the seismic source in exploration areas is commonly conducted by linking the Bigshot,GCSLink2000,and 428 XL cable systems.The GCSLink2000 master-slave synchronizer maintains strict synchronization between the two devices through the radio.However,when the distance between the two devices is too far,the signal weakens due to losses in the transmission path,leading to frequent invalid shots,seriously affecting the efficiency of the air gun vessel's operation.This article introduces a wired shooting technology for marine seismic exploration.The GCSLink2000 master synchronizer and auxiliary channels originally placed in the dog house are connected to the nearby water spread through the LAUX428 to shorten the radio communication distance between the master and slave synchronizers,improve communication efficiency,and enable the dog house to continue production without frequent relocation,thereby improving the efficiency of marine operations.
