FIELD: oil and gas industry.
SUBSTANCE: invention relates to oil and gas industry, in particular to oil production equipment, and can be used in oil industry to maintain steady-state operating conditions of well during oil production. Method comprises measuring pressure in well at intake of electric pump, maintaining specified pressure value in pipe string is performed by changing buffer pressure at wellhead by means of automatic change of local hydraulic resistance of controlled throttle by proportional-integrating differentiating (PID) regulator based on data of thermomanometric system on produced fluid column pressure at ESP unit reception, wherein the PID controller algorithm is built into the electric centrifugal pump installation control station software, controlled throttle is installed after linear gate valve of christmas tree, and submersible unit of thermomanometric system is made monoblock with ESP unit.
EFFECT: expansion of consumer properties, increase of reliability and efficiency of well operation, increase of equipment service life.
