Seismic Detector

摘要

A technique facilitates seismic wave detection with a seismic receiver. The seismic receiver has a tool body, a vibrationally isolated sensor package mounted in the tool body, and a plurality of contact shoes. The contact shoes are mounted around the sensor package in a distribution which enables three-point contact with a surrounding wellbore wall regardless of the azimuthal orientation of the sensor package.

1. A system for seismic detection, comprising:
a tool string; and a plurality of seismic receivers positioned along the tool string, each seismic receiver comprising:
a tool body;a sensor package coaxially placed in the tool body;an isolation spring system coupling the sensor package to the tool body; anda plurality of contact shoes for detecting seismic waves, the plurality of contact shoes being mounted to the sensor package and distributed along an exterior of the sensor package to establish three-point contact with a subterranean wall regardless of azimuthal orientation of the sensor package.
