METHOD FOR COMPLETION OF WELL Russian patent published in 2000 - IPC

FIELD: mining industry. SUBSTANCE: method is particularly intended for opening of productive beds in oil and gas wells. According to method, shaped charge or gas-generating charge together with chemical reagent are installed in casing string for completion of well. Gas-generating charge is initiated by shaped charge. Perforation passage is made in casing string and in surrounding productive bed. Introduced into perforation passage is gas created at combustion of gas-generating charge, then chemical reagent is also introduced into perforation passage. Chemical reagent contains the following components: hydrocarbon substance, 30-50; solution of oxidized petrolatum in diesel fuel, 3-4; emultal, 0.5-1.0; water solution of salts, 45-65. Application of method ensures enhanced productivity of oil and gas wells. EFFECT: higher efficiency. 1 dwg
