METHOD FOR DISPOSAL PROPELLANT CHARGES OF SOLID-FUEL ROCKET ENGINES Russian patent published in 2008 - IPC F42B33/06 E21B43/25 E21B43/18 

FIELD: methods of ammunition disposal.

SUBSTANCE: the method consists in extracting charges from an engine , their mechanical longitudinal cutting into uniform sticks with a maximum cross-section size not exceeding 100 m, placing said charge sticks vertically one over another into oil producing and injection wells filled with fluid and their burning in the near-wellbore zone. Charge sticks are delivered to the burning zone by means of a wire-line in a cylindrical container perforated with holes for products effluence in the central portion of the side face at a distance of 1/4 of the length from the both end faces, and then the sticks are burnt over their outer surfaces inflaming them by sending electric pulses simultaneously to the both igniters disposed on the bottom end face of the bottom stick and on the top end face of the top stick. According to the second variant, the container is perforated over its entire side face. The charge sticks are burnt over their end faces from top downward, by inflaming the top end face of the top stick.

EFFECT: ensuring reduction of disposal costs, enhancing technological effectiveness and environmental safety of the process.
