Abstract
An outer tubular is imaged by a pad assembly disposed within an inner tubular inserted within the outer tubular. The pad assembly is in contact with the inner tubular, and includes an acoustic pressure source, a backing mounted to a side of the acoustic pressure source, and an intervening layer between the acoustic pressure source and inner tubular. Signals generated by the pad assembly propagate radially outward from the inner tubular and reflect from the outer tubular. The generated and reflected signals travel through a medium between the inner and outer tubulars. An estimate of the distance between the inner and outer tubulars is based on the time from generation of the signal to when the reflected signal is sensed. The pad assembly and its components are during its design.
Claims (17)
1. A method of imaging in a wellbore comprising: inserting a pad assembly into an inner tubular that is disposed in the wellbore; forming an acoustic transmitter by contacting the pad assembly with the inner tubular; generating a vibration with the acoustic transmitter to form a transmitted signal that propagates radially outward from the inner tubular, into contact with an outer tubular that circumscribes the inner tubular, and through a medium disposed in an annulus between the inner tubular and outer tubular; using the pad assembly to sense a reflected signal that is formed by the transmitted signal reflecting from the outer tubular; and analyzing the reflected signal to obtain information about the outer tubular.
2. The method of Claim 1, wherein the pad assembly comprises an electroactive material, a backing mounted to a side of the electroactive material, and an intervening layer on a side of the electroactive material opposite from the backing.
3. The method of Claim 2, further comprising adjusting a density of one or more of the backing, electroactive material, and intervening layer so that substantially all of the vibration is transformed into the transmitted signal.
4. The method of Claim 1, wherein the information about the outer tubular comprises an estimate of a distance between the inner tubular and outer tubular, and which is based on a time difference from when the transmitted signal is generated to when the reflected signal is sensed.
5. The method of Claim 1, further comprising imaging a length of the inner tubular and estimating distances between the inner and outer tubulars along the length, and where the distances are used when imaging radially past the outer tubular.
6. The method of Claim 1, wherein the inner tubular comprises production tubing, and the outer tubular comprises casing that lines the wellbore.
7. The method of Claim 1, wherein the information about the outer tubular comprises a cement bond along the outer tubular.
8. A method of imaging in a wellbore comprising: operating an acoustic transducer that is disposed in the wellbore and that comprises an inner tubular; generating a transmitted signal with the acoustic transducer that projects radially from the inner tubular, and reflects from an outer tubular that circumscribes the inner tubular to form a reflected signal; sensing the reflected signal; and estimating information about the outer tubular based on a characteristic of the reflected signal.
9. The method of Claim 8, wherein the information about the outer tubular comprises positions of the outer tubular with respect to azimuthal locations of the inner tubular.
10. The method of Claim 9, wherein the acoustic transducer is part of a first downhole tool, the method further comprising deploying a second tool in the inner tubular and imaging a region radially past the outer tubular with the second tool, and wherein information about the region is obtained that is based on the step of imaging the region and the positions of the outer tubular with respect to azimuthal locations of the inner tubular.
11. The method of Claim 8, wherein the acoustic transducer further comprises a backing, an electroactive material mounted to the backing, and an intervening layer coupled along a surface of the electroactive material opposite from the backing and that is in contact with the inner tubular on a side opposite from the electroactive material.
12. The method of Claim 8, wherein the electroactive material comprises a piezoelectric transducer that vibrates in response to electricity.
13. The method of Claim 8, wherein densities, sound speeds, and dimensions of the backing, electroactive material, and intervening layer are strategically selected so that vibrations from the piezoelectric transducer create fluctuations in acoustic pressure in a medium outside of the inner tubular to form the transmitted signal.
14. A system for imaging in a wellbore comprising: an acoustic transducer that comprises, a means for generating a transmitted signal that propagates radially outward from an inner tubular inserted in the wellbore to an outer tubular that circumscribes the inner tubular, and that reflects from the outer tubular to form a reflected signal, and a means for sensing the reflected signal; and a controller in communication with the acoustic transducer.
15. The system of Claim 14, wherein the means for generating the transmitted signal comprise the inner tubular, an electroactive material, a backing mounted to a side of the electroactive material, and an intervening layer between the electroactive material and inner tubular.
16. The system of Claim 15, wherein densities, sound speeds, and dimensions of the electroactive material, backing, and intervening layer are strategically selected so the transmitted signal is formed by causing the electroactive material to vibrate.
17. The system of Claim 15, wherein the electroactive material, backing, and intervening layer comprise a first pad assembly, the system further comprising a plurality of pad assemblies each comprising an electroactive material, backing, and intervening layer, a body, and arms each having an end pivotingly coupled to the body and an opposite end connected to a one of the pad assemblies.
