MULTIFUNCTIONAL AUTOMATIC DIGITAL INTELLIGENT WELL Russian patent published in 2019 - IPC E21B47/00 E21B43/00 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to oil industry, in particular, to control of well fluid (WF) parameters and control in system of well operation optimization with installations of electric centrifugal pumps (ECP) according to well operation conditions and WF parameters. Disclosed is a multifunctional automatic digital intelligent well comprising submersible equipment consisting of a submersible centrifugal pump with a submersible electric motor, submersible heating cable line, electric communication line with submersible telemetry system, high-frequency generator with possibility of energy transfer to inductor and ground equipment station, comprising control device connected through inputs and outputs with ground and submersible equipment and possibility of controlling submersible electric motor, wireless and / or wire communication module with possibility to control, receive and transmit data via wireless and / or wire communication means, dosing pump, manometer, level gauge with possibility of transmitting information to a control device, a reagent flow meter with possibility of transmitting data on reagent consumption to a control device. At that well is additionally equipped with wellhead module (WM) having movable branch pipe and discharge branch pipe into main pipeline, and ground equipment is equipped with a voltage / frequency converter and a flow express analyzer of proton magnetic resonance (PMRA), which includes a magnet, a dielectric tube with an inductance coil of the PMR detector wound around it, output of coil is connected to power amplifier of radio-frequency pulses (transmitter) and useful PMR signals amplifier (receiver) of relaxometer by high-frequency cable with quarter-wave length, from receiver, through the module, information on the "smart well – proton magnetic resonance analyzer" multifunctional complex system is transmitted to the oil field monitoring and control dispatcher control panel.

EFFECT: technical result is expansion of functionality of multifunctional automatic digital intelligent well with heating of pumping and compression pipes and electromagnetic radiation of face with inductor.
