FIELD: oil and gas production.
SUBSTANCE: group of inventions refers to system and method of optimisation of production from oil or gas well by means of electric immersed pumps. The essence of the invention is as follows: according to inventions the following parametres of production on surface and in the borehole of well are controlled: pressure and temperature in a flow string, viscosity of fluid medium, rate of flow, pressure in a suction port and in a pressure port of the pump and temperature in the suction port of the pump. A system of detectors is used for control over parametres in the borehole of the well. Also the detectors are spaced in the well and they receive streaming of data on-line. According to the model of optimisation there are evaluated measured data obtained from plurality of parametres of production and plurality of well parametres. Operation of mechanism for artificial lifting is regulated on base of automatic evaluation of data and of their trends.
EFFECT: increased efficiency of production due to ability of timely elimination of potential problems adverse to production.
