Abstract:
Ultrasonic tomography (UT) is a non-invasive and radiation-free imaging technique for oil-water flow monitoring for its fast-acquisition and low-cost features. Conventional UT utilizes ray-based models, which simplify the ultrasonic wave propagation by neglecting wave-related phenomena such as refraction and interference. As a result, the simplification can lead to shape distortion and image artifacts in reconstructed images, particularly in oil-water flow where wave effects are significant. In this paper, we investigate ultrasonic wave propagation in oil-water flow through numerical simulations and lab-scale experiments. We first discuss the modeling inaccuracies in conventional ray-based model, which lead to significant errors in the forward problem. To address this issue, the ray-based model is replaced with the wave-based model, thereby improving the accuracy of forward wave propagation modeling. Subsequently, full waveform inversion (FWI) is introduced to solve the inverse problem of UT in industrial oil-water flow. Both simulation and experiment demonstrate that time-domain FWI with an adjoint field formulation is applicable to suppress the artifacts and provide reliable UT reconstruction in industrial oil-water flow.
