METHOD OF OIL AND GAS WELL CONTROL Russian patent published in 2015 - IPC E21B43/12 E21B47/00 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to oil industry, in particular to oil production from wells by the mechanised method, and can be used in any type of pump electric drives. Under the method at wellhead passive acoustic multi-phase flowmeter is installed. Well is operated using the rig with electric drive, and electric drive control station. Well yield and watercut as per phases are determined every second under real time mode. Yield is averaged for selected time period. Further yields as per phases are compared with set process parameters. If watercut values are beyond the set limits the amount of transferred by pump produced water is reduced upon keeping of the commercial oil yield at set level. For this one of action is performed: capacity of pump unit is reduced due to motor speed; capacity of pump unit is increased due to increasing of the motor speed; the pump unit is stopped for definite time for oil accumulation at the wellhead.

EFFECT: yield keeping at set level upon reduced power consumption.
