OCEAN BOTTOM SEISMIC SYSTEMS

摘要

A seismic sensor system includes a seismic sensor suspended in an acoustic medium, which is disposed between first and second sensor housings. The acoustic medium can be selected to preferentially transmit pressure wave energy, based on the acoustic impedance of the surrounding water column or other seismic medium. The acoustic medium can also be selected to preferentially dissipate or otherwise reduce the transmitted shear wave energy. The second housing can similarly be configured to dissipate shear wave energy, while transmitting pressure wave energy in the form of acoustic waves that propagate through the acoustic medium to the seismic sensor.

1. A seismic sensor system comprising:
a sensor housing in communication with a seismic medium; an acoustic medium disposed within the sensor housing, the acoustic medium selected based on an acoustic impedance of the seismic medium; and a seismic sensor suspended within the acoustic medium, wherein the sensor housing is configured to dissipate shear wave energy incident from the seismic medium and the acoustic medium is selected to transmit pressure wave energy from the seismic medium to the seismic sensor.
