摘要:
According to an embodiment, a seismic receiver device is described for use in a borehole surrounded by an ambient material, e.g., rock, mud, etc. The seismic receiver device includes a pressure wave measuring device which is configured to sense pressure changes associated with received seismic waves, a coating layer disposed on the pressure wave measuring device, and an outer layer disposed on the coating layer which is made of a material that is selected to have a bulk modulus number that is substantially similar to a bulk modulus number of the ambient medium. In this way, the acoustic impedance of the device is better matched to the ambient material so that more accurate seismic acquisition may be performed.
