Abstract
A system and downhole tool comprising an ultrasonic transducer with a piezoelectric material embedded in a backing and a method of determining a parameter using the ultrasonic transducer. A self-noise of the transducer can be reduced by the piezoelectric material being at least partially embedded in the backing. The ultrasonic transducer can include an encapsulating material that encapsulates the backing.
Claims21
A system comprising:
- an ultrasonic transducer comprising:
- a backing;
- and
- a piezoelectric material at least partially embedded in the backing.
A downhole tool locatable in a borehole intersecting a subterranean earth formation, comprising:
- an ultrasonic transducer comprising:
- a backing;
- and
- a piezoelectric material at least partially embedded in the backing.
A method of determining a parameter using an ultrasonic transducer, comprising:
- embedding a piezoelectric material at least partially in a backing;
- producing a signal in response to receiving an ultrasound wave with the piezoelectric material, a self-noise of the transducer being reduced by the piezoelectric material being at least partially embedded in the backing;
- and
- determining the parameter using the signal.
