METHOD FOR DEVELOPMENT OF OIL DEPOSIT Russian patent published in 1997 - IPC

FIELD: oil production industry. SUBSTANCE: this relates to increasing productive capacity of oil beds. According to method, injection and producing wells are drilled in multiple-bed oil deposit. Determined by means of hydraulic acoustics is presence of mutual influence between injection and producing wells and also determined is source of sharp flooding that is injection well. Found by calculation is volume of porous filler required for pumping into injection well. Used as liquid base is hydrophobic liquid or water polymeric solution with viscosity larger than viscosity of bed oil. After processing in injection well, initiated is treatment of intervals of water inflow in similar sets of all producing wells which are found in mutual influence with injection well. Technological methods are similar to treatment of injection well. After realization of directed acid treatment and subsequent flushing of wells, started is vacuumizing of producing and injection wells. Application of method allows only due to increased coefficient of embracing beds by flooding to increase productive capacity coefficient by 20%. EFFECT: high efficiency. 4 cl, 1 tbl
