METHOD OF BENCH TREATMENT Russian patent published in 2010 - IPC E21B43/263 

FIELD: oil-and-gas production.

SUBSTANCE: proposed method consists in that, first, bench is hydraulically fractured by hydraulic fracturing fluid to produce preset-length development fracture. Then hydraulically active fluid is pumped in the well and forced, by chaser, into the bench, formed fracture and adjoining rock pores. Said chaser reacts with water and suspension of aluminium-containing material activated by at least gallium, in anhydrous fluid-carrier to cause thermo baric effect on the bench so that rocks and fluid contained therein are heated by 20°C and higher due to decrease in oil viscosity to below 10 MPa·s, fluidising of paraffinic and asphaltene-pitchy hydrocarbons, extraction of gas-phase products and formation of asset of additional micro fractures branched off produced development hydraulic fracturing and communicated with the system of the bench natural fractures.

EFFECT: higher filtration properties of bench.
