Abstract

The invention relates to an acoustic positioning system, in particular to an acoustic positioning system of a shallow sea wave detector for secondary positioning of a seabed wave detector in shallow sea petroleum earthquake exploitation. The system mainly comprises a carrier-borne part and a seabed part, wherein the carrier-borne part consists of processing software, a host machine and a receiving and transmitting combined transducer; and the seabed part consists of a plurality of seabed transponders. Because the technology for manufacturing the receiving and transmitting combined transducer is adopted, the designed source level and the sensitivity meet the positioning requirement of a complex exploitation area of the shallow sea; and the underwater working posture of the transducer is kept and the turbulence and reverberation are reduced by designing streamline turning vanes. Therefore, the system meets the requirements of high recovery ratio and high positioning efficiency of secondary positioning of a secondary positioning earthquake exploitation water detector in the Bohai Bay area.

Description

1. Technical field: [0001] The invention relates to an acoustic positioning system, in particular to an acoustic positioning system for a shallow sea geophone used for secondary positioning of a seabed geophone in shallow sea petroleum seismic exploration. 2. Background technology: [0002] At present, the acoustic positioning system used for the secondary positioning of geophones in shallow sea oil seismic exploration is a blank field in China. In foreign countries, only two companies, Sonardyne Company of the United Kingdom and I / O Company of the United States, produce the source level and sensitivity of foreign products. , anti-interference ability and other hardware indicators are suitable for clear water areas on sandy seabeds, not suitable for turbid waters, especially not suitable for muddy areas where rivers flow into the sea. The operation mode of the display and control software is not suitable for the existing construction operation mode. In the application exampl...
