HEAT-RESISTANT GAS-GENERATING ACID-PRODUCING HIGH-STRENGTH FUEL FOR DOWNHOLE DEVICES Russian patent published in 2016 - IPC C06D5/06 C06B29/22 C06B29/02 

FIELD: fuel.

SUBSTANCE: invention relates to production of heat-resistant gas-generating acid-producing high-strength fuels for downhole devices of different action: borehole powder pressure accumulators, powder pressure generators, bullet and cumulative perforators for thermal gas-chemical and baric effect on bottomhole formation zone in oil and gas wells with simultaneous acid treatment for intensification of resources processing. Fuel includes an oxidant - ammonium perchlorate or potassium perchlorate, or mixture thereof, a combustible binder - a compound comprising α-oxide cycle- a product of interaction of epichlorohydrin with diphenylol propane, or a product of interaction of epichlorohydrin with oligodien, or a product of interaction of epichlorohydrin with diethylene glycol or triethylene glycol or mixture thereof, hydrocarbon oil, as well as it additionally contains a curing agent - an amine-type compound and a process additive - emulsifier of grade N-23 or 1,2-dialkylglycerocholyl-phosphate.

EFFECT: technical result is production of a fuel with high strength and heat resistance, increased content of acid-producing compounds - chloride and fluoride hydrogen in the combustion products.
