Abstract
This study adopts a comprehensive approach that integrates finite element simulations with experimental validation to investigate the potential application of ultrasonic imaging technology for downhole fallen objects detection. The study first employed finite element simulations to model the impact of fallen objects on acoustic wave propagation, with a focus on examining the correlations between the reflected signal and the fallen objects' spatial position, size, and the probe's excitation frequency. Based on the simulation results, an innovative ultrasonic imaging method for detecting fallen objects was proposed. Building upon the insights gained from numerical simulations, a dedicated experimental platform was developed to validate the proposed approach.
The model is developed using COMSOL. Due to the large size of the model and insufficient storage space, we can only briefly describe the parameters of the model here.
