METHOD FOR COMPLETION OF GAS INJECTION WELLS Russian patent published in 1997 - IPC

Abstract RU 2094597 C1

FIELD: oil production industry. SUBSTANCE: method allows for increased embracing of oil deposit by displacing agent. According to method, gas injection wells are initially operated as producing wells at bottom-hole pressure below saturation pressure. Fluid are taken from gas injection well until average gas saturation of collector reaches 0.5-10% of volume of reservoir pores. Then delivered into gas injection well is beneficated gas in volume required for achieving mixing displacement in reservoir, after that dry gas is injected into thus created fringe of beneficated gas by means of pressure-forcing. EFFECT: high efficiency. 1 cl
