METHOD OF SELECTING OPTIMAL MODE OF OIL WELL OPERATION Russian patent published in 2020 - IPC E21B47/10 E21B43/12 

FIELD: oil, gas and coke-chemical industries.

SUBSTANCE: invention relates to oil and gas industry and can be used in operation of oil wells. Method of selection of optimum operating mode of oil well, including equipment of well with deep pumps, lowering of bunch synchronized and located at certain distance by level of pressure gauges to the well, removal of curves of change of pressure drops on pressure gauges for determination of product density, from comparison of which with well flow rate there determined is mode of operation for bottom-hole pump, which enables to achieve maximum oil flow rate. Manifolds bunch is located below pump. Measurements are carried out at the operating deep-well pump, additionally equipped with an adjustable drive with a control unit, which is technologically connected to the bunch of pressure gauges and operating mode of the deep-well pump from the ratio of their readings within the range allowing to reach the maximum oil flow rate.

EFFECT: disclosed method makes it possible to carry out measurements in the process of controlled operation of the pump, including at high production rates with large changes of liquid level in the well and in wells with high gas factor.
