METHOD FOR CONTROLLING PARAMETERS OF LIQUIDS INJECTED INTO WELL Russian patent published in 2021 - IPC E21B43/12 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to the oil and gas industry and is intended for controlling the parameters of the liquid injected into the well when silencing wells during repair work. The method includes pumping liquid into the well while maintaining the set parameters, determining the pressure value that ensures no absorption of the injected liquid, monitoring the set parameters at the inlet and outlet of the well and regulating the parameters of the liquid at the outlet of the well. The parameters of the liquid are regulated to create a P_reservoir ≤ P_backwall condition. Information processing is carried out by comparing the specified parameters with each other.

EFFECT: invention provides an increase in the flow rate of the well, without reducing the production capabilities of the well and preserving the filtration and reservoir properties of the formation, preventing the penetration of liquid into the formation.
