摘　　要：地震电缆是有线地震仪器的重要组成部分,地震电缆的技术特性不仅直接关系到地震仪器的综合性能和应用效果,而且还直接关系到地震勘探生产的综合效益,有时甚至还关系到地震资料的品质。文章以通用对称通信电缆技术为基础,以地震勘探和地震仪器实际需求为目标,系统地讨论了地震电缆的传输技术特性和野外操作特性,明确了关键技术特性的物理意义、主要作用和计算方法,并结合实际工作经验提出了增强地震电缆技术特性和改进地震电缆应用效果的建议。Seismic cable is an important component of cable seismic instruments. The technical characteristics of the seismic cables are not only directly related to comprehensive performance and application effect of seismic instruments, but also directly related to overall efficiency of seismic exploration. Sometimes it is even related to the quality of seismic data. Taking the actual demand of seismic exploration and seismic instruments application as the goal, this paper discusses the characteristics of seismic cable＇s data transmission and field operating sys- tematically, and clearifies the key technical characteristics＇ physical significance, main role and calculation method on the basis of general symmetrical communication cable technique. Combined with practical work experience, it also gives the suggestions to enhance the technical characteristics and improve the application result of the seismic cable.
