Abstract: |
A novel method of hydrophone second positioning for oil exploration of ocean bottom was presented. To improvethe 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. |
