摘　　要：提出了海洋石油勘探中水听器二次定位的一种新方法,该方法使用1.5 kHz频段的低频声纳取代现有初至波定位系统的气枪来提高二次定位的精度。给出了新方法的系统组成及工作原理,对比了新方法与现有的水听器二次定位初至波方法及声波定位方法的优缺点,并通过计算机仿真、实验室测试证实了该方法的可行性。结果表明,新方法定位精度高,操作简单,便于维护。A novel method of hydrophone second pesitioning for oil exploration of ocean bottom was presented. To improve the precision of second positioning, it is suggested to use low-frequency ,sonar which works at 1.5 kHz wave band instead of air gun. The work principle of the new method and its system configuration were presented, the excellences were pointed out by comparing the new method with the existing technique of first break method for hydrophone second positioning. By computer simulation and the test results in lab, this method was proved to be practice. The results show the high precision of positioning, simple operating and convenient maintenance of this method.
