Problems solved by technology

The seismometer inside the submarine seismograph is a high-precision instrument, which is easily disturbed by external factors and affects the quality of data collection, especially the influence of submarine bottom currents.
Although the split-type submarine seismograph has made a breakthrough in the recovery rate, the quality of the collected data, especially the quality of the horizontal component, still needs to be further improved for the seismometer in the split-type submarine seismograph. The influence of the seismometer in the split seabed seismometer has not been completely eliminated, and the periodic compression of the seabed by long gravity waves in the ocean will cause low-frequency noise, which will also affect the quality of the data collected by the seismometer

Embodiment Construction

[0025] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only the parts related to the present invention are shown in the drawings but not all of them.

[0026] Such as Figure 1-5 As shown, this embodiment provides a self-buried seabed seismograph, which is used for the observation of natural earthquakes and is also suitable for the observation of artificial seismic sources. The self-buried seabed seismograph includes a seismometer module 1, and the seismometer module 1 includes a drill bit 11 and a driving assembly 12 for driving the drill bit 11 to rotate. A cavity is arranged in the drill bit 11, and a seismometer 13 is arran...

Abstract

The invention relates to the field of marine seismic observation equipment, and discloses a self-buried submarine seismograph. The self-buried submarine seismograph comprises a seismometer module. Theseismometer module comprises a drill and a driving component for driving the drill to rotate. The drill is internally provided with a cavity which is internally provided with the seismometer. According to the self-buried submarine seismograph, the seismometer is installed in the drill and the drill rotates into the submarine sedimentary strata under driving of the driving component so that the influence of the submarine flow on the seismometer can be effectively reduced, the influence of the low frequency noise caused by periodic compression of the long gravity waves in the ocean on the seismometer can also be reduced, and the data acquisition quality, especially the quality of the horizontal component data, of the seismometer can be enhanced.

Description

technical field [0001] The invention relates to the field of marine seismic observation equipment, in particular to a self-buried seabed seismograph. Background technique [0002] Seabed seismographs are widely used in the fields of research on crustal movement, resource exploration and development, imaging of the earth's internal structure, and monitoring of seabed dynamic processes. The seismometer inside the submarine seismograph is a high-precision instrument, which is easily affected by the interference of external factors and affects the quality of data collection, especially the influence of submarine bottom currents. Although the split-type submarine seismograph has made a breakthrough in the recovery rate, the quality of the collected data, especially the quality of the horizontal component, still needs to be further improved for the seismometer in the split-type submarine seismograph. The influence of the seismometer in the split submarine seismometer has not been...
