METHOD OF WAVE PROCESSING OF PRODUCTIVE FORMATIONS OF OIL DEPOSITS WITH MANIFOLD OF FRACTURE TYPE Russian patent published in 2012 - IPC E21B43/25 E21B28/00 

FIELD: oil and gas industry.

SUBSTANCE: method of wave processing of productive formations of oil deposits with manifold of fracture type involves determination of resonant characteristic of formation, use of wave generator and formation processing by means of waves with resonant frequency, which are created with generator. Besides, in order to determine resonant characteristic of formation, linear dimensions of pillars are measured, peculiar size of rock pillar is determined and row of resonant frequencies is calculated for wave processing as per the specified mathematical expression. Then, oil formation is processed by performing a series of in-series processings by radiation of waves of mechanical nature of the calculated row of resonant frequencies in frequency decreasing order. Mechanical-nature wave generator located in the well in the area of processed formation zone is used as wave generator.

EFFECT: increasing oil recovery of formations.
