Research On Gel Analyzer Based On Image Processing

As a chemical plugging and plugging agent,gel plays an important role in crude oil recovery and oil and gas recovery.The mechanical properties of gel are of great importance to the quality of oil well plugging.At present,there is no system for detecting the mechanical properties of Water Plugging Gel in the market,and most of the products on the market rely on foreign imports,and the price is more expensive.Therefore,through full investigation and research,a set of high precision and high reliability gel mechanical properties measurement system is developed by using digital image processing technology in order to solve the problem of low detection precision in the process of gel mechanical properties detection.The entire analysis system is composed of two major modules: displacement pump pressurization unit and machine vision unit.The software system is based on the modular programming language.The core of the analysis of gel mechanical properties is image processing.For the basic characteristics of capillary gel images,the gel image is first targeted for preprocessing;then a novel adaptive threshold segmentation algorithm is proposed to obtain a more accurate capillary.Gel concave surface;Finally,the gel concave surface is completely extracted to obtain the position parameters of the gel concave surface,and then combined with fluid mechanics theory to calculate the mechanical properties of the oil field production requirements.All data and images in the experiment will be stored in the database for the convenience of testers.In order to improve the accuracy of the instrument,this paper analyzes the most important mechanical properties of the gel: the possible error sources in the viscosity measurement process,and then the machine vision unit program is improved to make the instrument more mature and the measurement system has a higher degree of automation.After completing the design and construction of the smart gel analysis system,five different concentrations of gel samples were selected and compared with the results of a rotary rheometer.The tests showed that for the five gel samples,two measurements were performed.The measurement error between the methods is relatively small and remains within 5%: It is proved that the measurement system of gel mechanical properties studied in this paper has certain feasibility and reliability.
