FLOWMETER Russian patent published in 1994 - IPC

FIELD: oil production. SUBSTANCE: flowmeter has pumping unit with electric motor, downhole pump, static power converter whose output is connected with input of circuit of compensation of power losses of ground equipment. Output of compensation circuit is connected with input of circuit of scale setting for production rate whose output is connected with shaper of rated pulses. Output of pulse shaper is connected with switch whose first output is connected with rated pulses shaper, and the second output, with pulse counter, and third output, with input of shaper of intelligence pulses on production rate value, and the fourth output is connected with reset input of time relay. Output of time relay setting circuit is connected with input of time relay whose output is connected with input of circuit of shaping intelligence signals on production rate drop below preset value, whose output is connected with input of communication line running from well to group information point whose output is connected with one of inputs of microprocessor. Output of the latter is connected with input of transmitting device of teleautomatics system whose output is connected with input of communication line running from group information point to control point. Output of communication line is connected with input of receiver of teleautomatics system whose output is connected to microcomputer. EFFECT: higher efficiency. 9 dwg
