Embodiment Construction

[0032] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0033] A multiphase flow pattern discrimination method based on image processing, comprising the following steps:

[0034] S1, yes figure 1 The streamline boundary line in is processed. figure 1 There are three flow boundary lines in the flow pattern, namely Segregated flow (stratified flow) and Intermittent flow (intermittent flow), Segregated flow (stratified flow) and Distributed flow (dispersed flow), Intermittent flow (intermittent flow) and Distributed flow (Scattered flow) Three flow boundary lines, the fill color values ​​of each boundary line are as follows:

[0035] Segregated flow (layered flow) and Intermittent flow (intermittent flow): the RGB color value is (255, 128, 64);

[0036] Segregated flow (layered flow) and Distributed flow (dispersed flow): RGB color value is (128, 255, 255);

[0037] Intermittent flow (intermittent flow) and...

Abstract

The invention provides a multiphase flow pattern discrimination method based on image processing. The method comprises the following steps: firstly carrying out the recognition of flow pattern boundary lines in a flow pattern graph through an image processing technology, and filling a curve with different colors; secondly, filling the flow pattern areas enveloped by the flow pattern boundary lines with different colors, wherein the color filling adopts an RGB color value filling method; finally, determining positions of coordinate points in the flow pattern graph according to horizontal and vertical coordinate values of the flow pattern graph, reading color values of the coordinate points, comparing the color values with the color values of the flow pattern boundary lines and the flow pattern area one by one, and determining a flow pattern corresponding to the color if the values are equal. According to the method, the complex calculation and comparison process for judging the flow pattern through the flow pattern graph is simplified into the comparison of the color values of the coordinate points, so that the difficulty of autonomously judging the flow pattern by a computer is greatly reduced, and the accuracy and the efficiency of judging flow patterns are improved.

Description

technical field [0001] The invention relates to a method for discriminating flow patterns of multiphase flows based on image processing, and belongs to the technical field of flow pattern discrimination for oil, gas and water pipeline transportation. Background technique [0002] Oil-gas-water pipeline multiphase flow widely exists in onshore oil field gathering and offshore platform oil and gas gathering pipelines, including: gas-liquid two-phase flow, liquid-liquid two-phase flow, gas-solid two-phase flow, liquid-solid two-phase flow There are different types of phase flow, gas-liquid-water three-phase flow, horizontal tube multiphase flow, vertical tube multiphase flow, and inclined tube multiphase flow. For the complicated types of multiphase flow, scholars have established flow process calculation models for pipeline multiphase flow with different conditions, different scopes of application, and different multiphase flow mechanisms. [0003] Discrimination and division...
