Submersible buoy seismic data acquisition station

Abstract

The invention relates to a submersible buoy seismic data acquisition station which solves the problem of difficult marine seismic signal acquisition of the existing technology, and is composed of a hydrophone, a buoy, a connecting rod, a digital unit, a control module, a data communication unit, GPS and a power supply module. The buoy floats on the water surface. The hydrophone is placed underwater. The hydrophone and the buoy are connected through the connecting rod L. The digital unit, the control module, the data communication unit, the GPS and the power supply module are arranged in the buoy. The power supply module powers the digital unit, the control module, the data communication unit and the GPS. The control module establishes communication connection with an external host through the data communication unit, and receives an instruction of the external host or a preset instruction to control the digital unit, the data communication unit WU, the GPS and the power supply module. The data communication unit provides a communication service for the acquisition station. The digital unit converts an analog signal of the hydrophone into a digital signal. The GPS unit provides location information and a time marker for the acquisition station. The submersible buoy seismic data acquisition station has the advantages of good stability and noise reducing, and is conducive to improving the seismic signal receiving sensitivity and the signal to noise ratio.

Description

technical field [0001] The invention relates to a seismic data acquisition station, in particular to a submersible buoy seismic data acquisition station. Background technique [0002] High-precision digital seismograph is a geological exploration instrument used to record artificial or natural seismic signals, and then to find oil, gas, coal and other mineral resources based on the records of these seismic signals, and can be used to detect the internal structure of the earth, conduct engineering and geological Disaster prediction, etc. [0003] Seismic exploration method is still the main means of oil and gas exploration on land and sea, and also an important exploration method for other mineral resources, and is widely used in the study of the earth's internal structure, engineering exploration and detection, geological disaster prediction and so on. The basic method is to bury thousands or even tens of thousands of seismic wave sensors (ie, geophones) on the ground of th...
