METHOD RISING OIL RECOVERY FROM OIL POOL OF REPAIRED WELL Russian patent published in 2001 - IPC

Abstract RU 2163665 C1

FIELD: oil and gas production. SUBSTANCE: thermal wave radiation with frequency 400-2000 Hz and specific power of radiated thermal and wave energy not less than 10.0 kW per 1.0 m of thickness of pool is generated across face of well for action on pool. Low-frequency wave energy for relaxation of tension in pool is input by way of simultaneous formation in face zone of low-frequency periodic waves of decreased pressure with amplitude satisfying dependence P= Pf-0.8Psat, where Pf is pressure across face of well; Psat is saturation pressure of gas dissolved in oil. Frequency of low-frequency waves lies in range of 5-20 Hz. EFFECT: increased efficiency of wave action on oil pool to raise productivity of wells. 1 cl, 1 dwg
