DEVICE FOR CONTROL OVER THE WELLS PRODUCTION COMPONENTS FLOW RATE Russian patent published in 2018 - IPC E21B47/10 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to the oil and gas production industry and can be used to control the gas, gas condensate and oil wells production flow parameters. Device contains the controlled flow pressure and temperature sensors and a piezoceramic flow pressure pulsations sensor connected to the input of a broadband matching amplifier. Broadband matching amplifier outputs are connected to the inputs of the first, second and third active bandpass filters. First active bandpass filter output is connected to the programmable gain ratio amplifier first input. Output of the second one is connected to the first detector input, and the output of the third one is connected to the second detector input. Programmable gain ratio amplifier output is connected to the first input of the two-channel analog-to-digital converter. First detector output is connected to the second input of the two-channel analog-to-digital converter through a series-connected integrator and a scaling amplifier. Second detector output is connected to the pulses generator first input through the level comparator, to the second input of which the reference frequency clock pulse generator is connected. Outputs of the dual-channel analog-to-digital converter, scaling amplifier, pulses generator and pressure sensors and controlled flow temperature are connected to the microprocessor controller first, second, third, fourth and fifth information inputs, respectively, which said outputs are connected to the digital interface inputs, and its control output is connected to the programmable gain ratio amplifier second input.

EFFECT: achieved technical result consists in providing, in addition to the information on the number of particle impacts of sand impurities and water impurities per unit of time determined by the impact signal exceeding of the predetermined threshold value, information on the impact action parameters, determined by the impurity particles mass and velocity, due to the generation of the signals proportional to the impact action intensity.
