单道地震勘探因其施工灵活，方法简单，工作效率高、定位精确等优点，在海洋区域地质调查中的应用范围越来越广，但是其震源系统多为电火花，激发频率高，能量低。这种震源在水中因深度加大衰减严重，且穿透力较弱，无法适应深水、深层地层资料的采集要求；空气枪震源具有能量大，频率低，穿透力强等特点，能够延伸单道地震勘探的范围。本文结合实际生产，结合空气枪震源系统与单道记录系统同步联机中的硬件配置、系统设置、时序等问题的分析，给出了解决方案。

Because of the flexibility,efficiency and accuracy of positioning,the application of the single-channel seismic acquisition in the marine geological survey is getting more and more widely. But its maj or source system is spark,with high frequency but low energy,which severely attenuates due to the increase of the depth of water. So the spark source can’t adapt the requirements of the deepwater acquisition;in this case,air-gun source system with low frequency but high energy and capability of penetration can effi-ciently extend the range of the single-channel seismic acquisition. This article is based on the actual field operation,some solutions were put forward to the problems in hardware configuration,settings and se-quence in time between the systems.
