METHOD OF EXPLOITATION OF OIL FIELD Russian patent published in 2000 - IPC

FIELD: oil industry. SUBSTANCE: method can be used to increase productivity of oil wells at stage of their development and subsequent industrial exploitation. Proposed method ensures increased productivity of oil well by way of decrease of viscosity and exclusion of two-phase filtration of stratal oil in face zone thanks to artificial drop of saturation pressure of oil by gas. Method includes drilling of operating well with vertical or horizontal shaft in productive part of section and installation of packer. String clearance is isolated from produced oil. Well is perforated and accepted by conducting operations to induce inflow of stratal fluid and to clean face zone of pool. Well is examined and subsequently run. In process of exploitation concentration of liquid hydrocarbons " pentanes plus supreme " in face zone is kept higher in comparison with initial concentration by their periodic or constant pumping into pool. Hydrocarbons " pentanes plus supreme " are pumped periodically in composition of hydrophobic microemulsion containing 0.1-0.4 parts of aqueous acid-forming phase dispersed in 0.6-0.9 parts of hydrocarbons correspondingly. EFFECT: increased productivity of oil well. 2 cl, 3 dwg
