Vertical oil-water phase content measurement and verification method based on frequency complex network

A vertical oil-water phase content measurement and verification method based on frequency complex network is as below: constructing a frequency complex network; calculating parameter measurement information of a vertical oil-water two-phase flow; mapping an average frequency clustering coefficient, an average frequency betweenness and a transitivity and oil content linearly relation measurement plate, so as to achieve the measurement of oil content of the vertical oil-water two-phase flow; and analyzing the dynamic relationship of average frequency clustering coefficient, average frequency betweenness and transitivity with flow pattern evolution according to the measurement plate, in order to reveal the flow pattern evolution dynamic mechanism of the vertical oil-water two-phase flow. The verification method employs a multi-electrode distributed conductance sensor for verification. The invention conducts information fusion on the measuring signals of the two-phase flow multi-electrode distributed conductance
