STRING OF SENSOR ASSEMBLIES HAVING A SEISMIC SENSOR AND PRESSURE SENSOR

摘要

A system includes an electrical medium and a string of sensor assemblies having corresponding outputs connected to the electrical medium, where at least one of the sensor assemblies includes a seismic sensor to measure seismic waves propagated through a subterranean structure, and a pressure sensor. The sensor assembly further includes at least one matching circuit connected to an output of at least one of the seismic sensor and pressure sensor, where the at least one matching circuit is configured to suppress noise. An output signal of the at least one matching circuit is connected to the electrical medium to produce a combined signal that is representative of characteristics of the subterranean structure and in which the noise is suppressed.
