Granted: 2019-11-11
Abstract: FIELD: oil and gas industry. 
     SUBSTANCE: invention relates to oil industry and can be used in wells with high pressure of associated gas in annular space and low dynamic level. According to the method, a bypass line is mounted parallel to the main hydraulic line of the well fluid extraction at the wellhead shutoff valve through an additional tee and a shutoff valve installed between the manifold of the manifold valve and the lubricating shutter of the wellhead shutoff valves. Manometer and jet device are installed on it. Mixing chamber of this device is connected to annular space of the well. Fluid lifted to surface by pump is used as working flow for operation of jet device. Electric centrifugal or electrically driven or electric diaphragm or valve pump is used as the pump. Each of them has the possibility of regulating the rotational speed of the submersible electric drive shaft under various operating conditions, changing the supply and pressure. When reducing pressure in annular space of the well and increasing dynamic level in the well, the efficiency of the submersible subsurface pump is increased due to increased rotation speed of the shaft of the submersible electric drive. High-energy flow of borehole fluid is created in confusor of jet device, due to which rarefaction is created in mixing chamber of jet device. Gas from annular space is mixed with this flow and injected via diffuser into well fluid extraction line. Flow of borehole fluid along main line of wellhead shutoff valves is shut off by manifold valve with either electromagnetic or mechanical valve. On main line of wellhead shut-off valves there is a choke chamber or a gate valve for pressure control on the buffer. At that, control of operation of deep pumping equipment and jet device is performed by changing the flow section in the confusor and diffuser of the jet device, as well as by changing the rotational speed of the submersible electric drive shaft. On the bypass line after the jet device, an additional shutoff gate valve and a sampler are installed. Line pressure is controlled by pressure gauges and pressure gages to transmit data to control station. Pressure at pump intake is controlled by sensors of telemetry unit installed on submerged electric drive. Data from sensors are transmitted to control station and dispatcher panel for control and automatic control of equipment operation and solenoid valve. 
     EFFECT: increased efficiency of reduction of excess pressure of associated oil gas in annular space of oil well, increased efficiency of gas-oil equipment operation and increased oil recovery.
