摘要： A device and method used to log images of cylindrical fluid filled tubulars with ultrasound transducers. The transducers operate as phased arrays, insonifying the conduit at plural angles. Reflections from the conduit form images that are combined to create a compound image or correct eccentricity. The frame rate is sped up by defocusing the transmitted beam. This allows the device to log very long pipelines, wells or other tubulars with very high resolution.
