METHOD OF INCREASING EFFICIENCY OF OIL PRODUCING WELLS Russian patent published in 2024 - IPC E21B43/12 F04F5/54 

FIELD: oil, gas and coke-chemical industry.

SUBSTANCE: invention relates to the oil and gas industry and can be used to reduce line pressure and increase production of oil producing wells using a jet pump, active medium of which is water from formation pressure maintenance system (PMS), and the passive medium is a flow of a gas-liquid mixture coming from an automated group metering unit (AGMU). In the method of increasing the efficiency of oil production wells using a jet pump, the active agent of which is water from the reservoir pressure maintenance system, well products supplied from a group of wells through the AGMU are supplied to the jet pump. Inlet chamber and the mixing chamber of the jet pump are connected through a bypass line of well products with an electromagnetic gate valve to the oil-gathering manifold. Passive agent of the jet pump is a well product in the form of a gas-liquid mixture. Water flow head is controlled during operation of the jet pump by means of a disk gate valve with a set of unions located on the line for supplying the active agent to the jet pump from the pressure maintenance system.

EFFECT: high efficiency of a group of producing oil wells with a low gas factor due to an increase in the inflow of an active agent, water from the reservoir pressure maintenance system to the well and an increase in its dynamic level in the annular space.
