摘　　要：针对海上石油地震勘探过程中,船体转弯时拖缆尾靶之间容易发生缠绕的问题,提出可控尾靶设计方案,利用固定在系统支撑架上的声学装置对电缆尾部位置进行实时监测,通过微处理器控制传动机构实现舵攻角的变化,实现电缆尾部位置的调节,使各可控尾靶之间的距离达到设定目标距离,避免尾部电缆发生缠绕。In the process of offshore oil seismic exploration, the towing tail buoys can easily get twining while the ship is making a turn. For the tail cable twining problem, a design scheme of controllable tail buoy was proposed. The working principle of controllable tail buoy is to use the acoustic device fixed on the system support frame for real-time monitoring at the cable’s tail position;then through the microprocessor control actuator work to implement the rudder angle of attack changes, so as to achieve the adjustment of the cable’s tail position, and make the distance between each controllable tail buoy achieve the setting target distance, finally avoid tail cable twining.
