空气枪震源的技术应用
|
摘要
以往在水域广阔的地区进行地震勘探,常因放炮受限制而得不到完整的地震资料。本文介绍了一种适合在水网区进行地震勘探的震源——空气枪震源,简明阐述了气枪控制器的工作原理、气枪与仪器的连接方式及其相关要求。采取本文介绍的连接方式可增加延迟时间或者加大时断检测窗的长度。
Complete seismic data can not be achieved due to the limitation of shooting conditions in vast water area. This paper introduces an air-gun source suitable for seismic exploration in lakes and ponds. It briefly presents the operating principle of the air-gun controller,the connection method between the air-gun and instrument and relative requirements. The delay-time can be increased or the length of time-break monitor-ing window can be enlarged by use of the connection methods given in this paper.
