METHOD OF HYDROCARBON POOL DEVELOPMENT Russian patent published in 2002 - IPC

FIELD: development of hydrocarbon pools; applicable in final withdrawal of hydrocarbons from pools. SUBSTANCE: method includes withdrawal of hydrocarbons through producing wells; determination of dominant frequencies of source of vibroseismic treatment for two pairs of neighboring wells by detection of hydrocarbons with viscosity and/or density higher than those of hydrocarbons of said pool. Vibroseismic treatment of formation is carried out in interval between said pairs of wells with dominant frequency within preset dominant frequencies. Composition and quantity of produced fluid are controlled. With increased well productivity, withdrawal of fluid through producing wells is forced. EFFECT: increased recovery of oil due to restoration of mobility of oil viscous component. 3 cl, 3 ex
