Seismic streamer construction for minimizing hydrophone response to vibration produced pressure fields

摘要

A marine seismic streamer construction for minimizing hydrophone response to vibration produced pressure fields, wherein a pair of hydrophones in the outer tubular jacket or hose are supported on the faces which confront each other of a pair of tightly fitted pistons in the jacket firmly secured to the steel towing cables of the streamer and located close together so that substantially the same motion in phase, amplitude and frequency is imparted to both pistons and the hydrophones produce outputs of opposite sign responsive to sound pressure fields caused by vibrating motion of the streamer components.
