Annotation:
The article is devoted to solving the problem of monitoring flow parameters of complex wells production flows, including water and sand impurities. Original methodological and technical solutions that make it possible to isolate an informative signal about the amount of impurities in a gas flow based on an analysis of the impact signals characteristics recorded by the developed primary measuring transducer characteristics are described. The totality of the studies carried out allows concluding that the impact of water drops causes a continuous random signal in the lower ultrasonic range, the intensity of which depends on the flow rate speed and the content of water impurities, and the impact signal of sand impurities is recorded in the upper ultrasonic range, but looks different, which requires another scheme-technical solution for registration of this type of impurities. New technical solutions are described, on the basis of which measuring channels for detecting impurities are built, and the results of laboratory studies of these channels are presented. The results of the development and positive testing of unified information models for determining the amount of impurities are also shown, which allows making conclusions about the prospects for the practical implementation of the solutions obtained in "Potok-6", the new generation wells operation monitoring system (information-measuring system, IMS).
