The invention provides a high-temperature-resistant
propellant for an oil / gas deep well. The high-temperature-resistant
propellant is prepared from the following raw materials by weight percent: 30 to 58 percent of
potassium perchlorate, 2 to 30 percent of 1,1'-dihydroxyl-5,5'-bistetrazole dihydroxylamine salt, 10 to 20.90 percent of high-temperature-resistant
epoxy resin, 0 to 16.58 percent of
bisphenol A
epoxy resin, 4.75 to 13.03 percent of
epoxy resin active diluting agent, 0.5 percent of
accelerant boron trifluoride-amine complex, 0.03 percent of a defoaming agent, 6.57 to 8.14 percent of diaminodiphenyl
sulfone, and the sum of the weight percentage of the raw materials is 100 percent. The raw materials of the
propellant are mixed after being pre-mixed, and then the
mixed materials are formed by virtue of a mold to produce a finished product. After the
solid propellant is immersed in
clean water and 3.5%
saline water for 24 to 48 hours, the
weight loss of the
solid propellant is less than 3 percent, and the
volume variation is less than 2 percent; the temperature-resistant grade can reach 200 DEG C for 48 hours, the
spontaneous combustion of the propellant can be avoided, and the high-temperature-resistant propellant can be used in a high-temperature watery environment.
