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

FIELD: development of hydrocarbon pools, applicable in performance of measures for final withdrawal of hydrocarbons from pools. SUBSTANCE: method includes withdrawal of hydrocarbons from producing wells. Development is carried out by sections of development with location of wells with sources of hydraulic pulse depression-repression treatment of bottom hole zone at corners of sections, and sources of vibroseismic treatment on day surface of development sections. Dominant frequencies of vibroseismic treatment source are determined for two pairs of neighboring wells by appearance of hydrocarbons with viscosity and/or density higher than those of hydrocarbons produced from said hydrocarbon pool. Vibroseismic treatment of formation is carried out in the interval between said pairs of wells above sections with elevations of producing formation with dominant frequency within definite dominant frequencies. Determination of dominant frequencies in hydraulic pulse depression-repression treatment is carried out in each well by appearance in neighboring producing wells of hydrocarbons with viscosity and/or density higher than those of hydrocarbons produced from said pool. When well productivity rises, withdrawal of fluid through producing well is intensified. EFFECT: higher recovery of hydrocarbons due to restoration of mobility of viscous component of oil. 3 cl, 3 ex
