The process information acquisition of horizontal oil-water two-phase flows is a common challenge in petroleum and chemical industries. This project studies the methodologies of using a combination of an ultrasonic/electrical sensor-array to measure the non-uniform oil-water two-phase flow. The multi-sensitive field coupling simulations of two-phase flow field, electrical sensing field and ultrasonic sensing field are conducted, in order to investigate the distribution characteristics of electrical sensing field and the attenuation, velocity and Doppler effect of ultrasound that modulated by the dynamic response of a polydisperse and non-uniform horizontal oil-water two-phase flow; Allocation of the dual-modality sensor array is optimized on the spatial sensitivity and information acquisition to obtain the comprehensive information about the flow process; The multi-parameter and multi-scale features are extracted by multi-variant time series analysis; A physical two-phase flow model is built based on efficient multisource information fusion models derived from the analysis of the correlative character and information fusion of the dual-modality sensors data; The dual-modality multi-sensor data acquisition system is developed for the purpose of acquiring the flow characteristics of oil-water two-phase flow in a comprehensive, real time and accurate manner. This system provides a non-intrusive and radiation free measuring approach for the researches of multiphase flow and industrial applications.
