Method and apparatus for deployment, mounting and coupling of downhole geophones

摘要

A method of and system for anchoring at least one acoustic device 40 against a borehole or wellbore wall 14 where the acoustic device 40 is attached to an anchoring device 20; a tubing 18, provided with the anchoring and acoustic devices, is then placed within a borehole and the anchoring device 20 is extended to the borehole wall 14 in order to couple the acoustic device to the borehole wall 14. The acoustic device may include at least one of a plurality of seismic motion sensors; at least one source and a combination including at least one acoustic source and at least one acoustic detector. The acoustic device may be attached to the anchoring device so that the acoustic device is located in the annulus between the tubing and the borehole wall when the tubing is placed in the borehole.
