METHOD FOR INCREASING RESERVOIR RECOVERY Russian patent published in 2009 - IPC E21B43/16 

Abstract RU 2355878 C2

FIELD: oil and gas industry.

SUBSTANCE: invention refers to oil industry and can be implemented for increasing yield of well and intensification of oil extraction. The essence of the invention is as follows: the method consists in lowering well vibration acoustic emitter into a well to the level of producing reservoir and in performing acoustic effect onto the reservoir. According to the invention effect onto the reservoir is performed with multifrequency signal, containing at least two monochromatic constituents, frequencies and amplitudes of which meet the condition expressed by analytical dependence. Also this effect is performed before oil withdrawal and/or in the process of oil withdrawal and/or at well shut-down.

EFFECT: increased efficiency of method due to effect onto fluid in porous space of well with multifrequency effect.
