Model optimization of phase fraction in oil-gas-water three-phase flow using ultrasonic testing technique
摘要
Abstract
Oil-gas-water multiphase flow is pervasive in oil and gas industry processes.However,the current phase fraction model for oil-gas-water multiphase flow limits to fully exploit the measurement information from ultrasonic transducers.To solve this problem,an optimized phase fraction model that employs an ultrasonic testing technique in water-based dispersed stratified flow was proposed.Using the maximum particle size model,the variations in particle size in water-based dispersed stratified flow was studied,and the particle size-wavelength ratio resides within the intermediate wavelength regime was determined.Moreover,a"one-transmitter-three-receivers"test system was adopted based on the ultrasonic pulse-echo method and developed a testing method for ultrasonic diffusion attenuation in water-based dispersed stratified flow.Subsequently,it was integrated Faran's elastic scattering theory to establish an ultrasonic testing model for oil fraction in oil-water dispersed flow.Utilizing time-of-flight measurement information,a modified parameter to account for fluctuations in the ultrasonic propagation path were proposed.This allowed to enhance the testing model for mixed sound velocity in oil-water dispersed flow and further optimize the gas fraction testing model.Simulation results showed that the mean relative error(MRE)and root mean square error(RMSE)for gas fraction prediction in water-based dispersed stratified flow were 0.43%and 0.23%respectively,while the MRE and RMSE for oil fraction prediction were 3.30%and 0.28%respectively.These results confirm the efficacy and precision of the proposed optimized testing model for phase fraction based on mixed sound velocity,thereby providing a theoretical foundation for ultrasonic testing methods in oil-gas-water multiphase flow.关键词
