    摘要: Systems and methods of the present disclosure relate to non-intrusive tracking of objects in a conduit from a single location. A system comprises a component positioned to control flow into or out of the conduit to induce pressure waves in the conduit; a pressure transducer in fluid communication with the conduit, the pressure transducer positioned to measure pressure responses in the conduit due to contact of the pressure waves with the object; and a system controller operable to: receive pressure data from the pressure transducer, wherein the pressure data includes the pressure responses to the pressure waves; and determine a distance of the object in the conduit, relative to the component or the pressure transducer, based on the pressure responses.

    摘要: A downhole tool system includes a downhole tool that includes a tool body configured to move within a wellbore, a depth detection sub-assembly and configured to generate a signal based on a known depth location of the tool body in the wellbore, an acoustic transmitter sub-assembly including an acoustic pinger configured to generate acoustic pulses, and a measurement and control sub-assembly configured to receive the signal from the depth detection sub-assembly and, based on the signal, activate the acoustic transmitter sub-assembly to initiate the acoustic pulses from the acoustic pinger. The system further includes a control system that includes a fiber optic interrogator communicably coupled to a fiber strand installed in the wellbore and configured to determine a travel time of the tool body along the fiber strand or a particular distributed acoustic sensing (DAS) channel of a plurality of DAS channels based on a detection of at least one disturbance in the fiber strand caused by the acoustic pulses.
