摘要

侧吊式气枪阵列模式更适合于靠近岸边的浅水域地震勘探施工,具有转向和调头非常灵活等特点,扩展了气枪船在浅水区可安全施工的面积。后拖式气枪阵列模式更适合于较深水域的气枪震源施工,由于气枪震源距离船尾较远,产生的气枪激发振动对船内设备的损坏也相应减小。本文介绍的组合拖曳模式是在一条船上有机、灵活地将这两种模式组合在一起,使一条船同时具备两种气枪阵列单独工作的能力。该组合模式可在很短的时间内进行模式转换。经现场施工证实,该方式简单、易行,提高了施工效率。
The seismic air-gun array under side-hook mode is more suitable for the very shallow water area which is more close to the offshore.This kind of mode is easy for air-gun boat turning and reverse,so the shooting area can be expandable.The air-gun array with towing mode is suitable for the deeper water area.The vibration to the inner machinery and electrical equipment is much more less affect than the from the side-hook mode.A compound air-gun array towing mode was accomplished on one air-gun boat,so the boat can have two kinds of air-gun array hooking & towing mode.The compound hooking & towing mode is quick exchangeable,it is effective for the field shooting and have the respective advantage of the side hooking and towing behind mode.It has been approved by the project shooting that the invented compound mode is easy for the operation,and increasing production efficiency.
