METHOD AND APPARATUS FOR SEISMIC EXPLORATION

摘要

An acoustic and vibrational noise shielding device for use in association with a geophone (1) in a method of seismic exploration comprises a cover element (7) adapted to substantially surround the geophone when the geophone is located in an operating position and means (10) for retaining the geophone when the geophone is removed from the operating position, the arrangement being such that when the geophone is located in the operating position, the geophone is substantially isolated from the shield device.
