    摘要: Aspects of the present disclosure relate generally to analyzing subterranean cylindrical structures using acoustic sensing. On example includes: sending first acoustic waves in the wellbore via a radial acoustic sensor; receiving first reflection waves associated with the first acoustic waves via the radial acoustic sensor; sending second acoustic waves in the wellbore via the radial acoustic sensor; receiving second reflection waves associated with the second acoustic waves via the radial acoustic sensor; processing recorded data associated with the first acoustic waves, the first reflection waves, the second acoustic waves, and the second reflection waves, wherein the first acoustic waves are associated with a first radial direction, and wherein the second acoustic waves are associated with a second radial direction, the second radial direction being opposite the first radial direction; and generating a plot for identification of one or more isolation regions in the wellbore based on the processing.

    摘要: The invention provides a method and apparatus for assessing a condition of a fluid conduit from its interior. The method comprises providing a measurement apparatus comprising at least one wideband acoustic transducer within the fluid conduit and transmitting a wideband acoustic signal from the measurement apparatus to excite a broadside resonance in at least a portion of the fluid conduit. A wideband acoustic signal is received in the measurement apparatus due to a broadside resonant response of the fluid conduit to obtain a wideband acoustic data set; and the data set is analysed to assess the condition of the fluid conduit.

    摘要: A method of and apparatus for assessing a condition of a fluid conduit is described. The method comprises providing a measurement apparatus comprising at least one wideband acoustic transducer internally or externally of a fluid conduit, and transmitting a wideband acoustic signal from the measurement apparatus to excite at least a portion of the fluid conduit. A wideband acoustic signal is received in the measurement apparatus to obtain a wideband acoustic data set; the wideband acoustic data set is analysed to assess the condition of the fluid conduit. The wideband acoustic signal comprises frequencies in the range of approximately 10 kHz to approximately 150 kHz. Applications include detecting or assessing a layer or deposit on an interior of the fluid conduit and assessing a physical condition of the fluid conduit. Water ingress into an annulus of a multiple layer conduit (such as a flexible riser) may be detected.

    摘要: Implementations described and claimed herein provide systems and methods for isolation detection. In one implementation, recorded data is obtained. The recorded data includes radial acoustic waves transmitted and received using a radial sensor of an acoustic logging tool deployed in a wellbore. Clockwise waves are separated from counterclockwise waves by converting the recorded data from a time domain to a frequency domain. The clockwise waves are shifted into shifted clockwise waves, and the counterclockwise waves are shifted into a shifted counterclockwise waves. A forward wave is generated by combining the shifted clockwise waves, and a reflected wave is generated by combining the shifted counterclockwise waves. One or more isolation regions are identified in the wellbore using the forward wave and the reflected wave.
