METHOD OF ADDITIONAL DEVELOPMENT OF WATER-FLOODED SECTIONS OF GAS-CONDENSATE DEPOSIT OF OIL AND GAS CONDENSATE DEPOSIT Russian patent published in 2021 - IPC E21B43/20 

FIELD: oil, gas and coke-chemical industries.

SUBSTANCE: invention relates to oil and gas industry, namely, to additional development of gas condensate deposit at the final stage of operation, and can be used for joint production and development of residual hydrocarbons and industrial water. Method involves water pumping through sieve of injection wells into productive formation and extraction of formation fluids through production well grid, additional development is carried out in sections connected with main tectonic blocks of deposit, pumping of water is carried out through injection wells by controlled bypass of compatible formation water from underlying high-pressure water-bearing horizon with achievement of piezometric level in borehole, extraction of formation fluid is performed by pumping production with yield, corresponding to fluid inflow to the bottomhole of the production well with maximum possible depression for all types of depression in pulsating mode as per well flow rate.

EFFECT: technical result is increase of hydrocarbon yield, efficiency of deposit development and diversification of products of wells due to additional extraction of residual gas and condensate, extraction and processing of industrial water.
