FIELD: oil and gas industry.
SUBSTANCE: acid-generating solid-fuel composition includes the following components, wt %: ammonium nitrate 35-40, thrifluorochloroethylene copolymer with vinyledine fluoride 5, elastomeric copolymer of vinyledine fluoride and chlorotrifluoroethylene with particle size of 0.5-1.5 mm 10-12, polyvinylchloride with mol. mass of 25-50 thous. 43-50.
EFFECT: increased combustion temperature, combustion rate and calorific value of acid-generating solid-fuel composition at high combustion stability in the wide pressure range, increased efficiency of the impact on bottomhole formation zone matrix comprised of carbonate and terrigenous rocks and on silicate impurities in the bottomhole zone, reduced slagging, capability of the composition to be processed by extrusion method.
