摘要：
Methods of acoustically and optically probing an elongate region and hydrocarbon conveyance systems that utilize the methods. The methods include actively initiating an acoustic signal within an acoustic waveguide that extends along an elongate region. The methods also include optically detecting propagation of the acoustic signal along a length of the acoustic waveguide with a distributed acoustic sensor. The distributed acoustic sensor includes an optical fiber that extends along the length of the acoustic waveguide and defines a plurality of distributed sensing locations. The hydrocarbon conveyance systems include a tube that defines a tubular conduit configured to convey a hydrocarbon, a distributed acoustic sensor, an acoustic waveguide, and a controller. The tube, the distributed acoustic sensor, and the acoustic waveguide extend within an elongate region. The controller is programmed to perform the methods.
