DEVELOPMENT METHOD OF BOTTOM-HOLE FORMATION ZONE Russian patent published in 2012 - IPC E21B43/243 E21B43/267 E21B43/27 

FIELD: oil and gas industry.

SUBSTANCE: in processing method of bottom-hole formation zone, which involves pumping to the formation of magnesium granules with further pumping of acid compound, first, hydraulic fracturing of the formation is performed with further pumping of mixture of magnesium granules and propane with fluids on hydrocarbon or water basis. Then, to the processed zone of the formation there pumped is combustible oxidation composition (COC) which contains oxidiser, catalyst decreasing the value of the temperature required for the beginning of oxidation reaction, surface-active substance required for removal of hydrocarbon film from magnesium, and water. After oxidation reaction is completed and additional cracks are formed, acid compound increasing the size of the formed cracks is pumped.

EFFECT: increasing processing efficiency of the bottom-hole formation zone at increasing safety of the work execution process.
