Downhole acoustic sensing tool and method

An acoustic sensing tool for use with a carrier disposed in a wellbore may include a base and a resilient clamp disposed around the base. The clamp may move between a retracted position, in which the clamp interior surface engages the carrier, and an expanded position, in which the clamp exterior su...

Zusammenfassung:An acoustic sensing tool for use with a carrier disposed in a wellbore may include a base and a resilient clamp disposed around the base. The clamp may move between a retracted position, in which the clamp interior surface engages the carrier, and an expanded position, in which the clamp exterior surface engages the wellbore. A sensor is coupled to the clamp. An actuator is movable along the base and operably coupled to the clamp. The actuator is operable to move the clamp between the retracted and expanded positions and configured to maintain contact with the clamp in both the retracted and expanded positions so that movement of the actuator in a first direction causes the housing to move to the expanded position, and movement of the actuator in a second, opposite direction causes the housing to move to the retracted position.
