Problems solved by 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 examples of seismic exploration projects, there are generally prominent problems of low recovery factor and low work efficiency

Embodiment Construction

[0018] combined with Figure 1-7 , to further describe the present invention:

[0019] Refer to attached figure 1 , the present invention consists of a shipboard part A and a seabed part B, the shipboard part is made of a processing software 1, a host computer 2, and a transponder 3 that is combined for sending and receiving, the seabed part is a large number of seabed transponders 4, and peripheral devices that can be connected Including differential GPS and depth sounder, etc., wherein the processing software 1 is a technology well known to those skilled in the art, and will not be described in detail.

[0020] Refer to attached figure 2 , where the transmitting / receiving transducer completes the conversion between the electrical signal and the acoustic signal, transmits the inquiry signal, and receives the response signal; the guide vane is the carrier towed by the transmitting / receiving transducer, and realizes the Stable towing; the pre-amplification of the hydrophone...

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.
