COMPOSITION OF THERMAL SOURCE FOR TREATMENT OF BOTTOMHOLE ZONE OF WELL Russian patent published in 2011 - IPC C09K8/528 C09K8/594 

FIELD: gas and oil production.

SUBSTANCE: composition of thermal source for treatment of bottomhole zone of well consists of granulated ammonia saltpetre of grade B, bi-chromate of potassium, epoxy resin of grade ED-20, plasticiser EDOS, and hardener Agidol of grade AF-2M. As components increasing strength of material of composition and temperature of its combustion compression this composition contains mixture of powders of aluminium of dispersity not over 50 mcm and nitro-acid barium of dispersity not over 0.5 mm at the following ratio of composition components, wt %: said saltpetre 52.5-53.0, potassium bio-chromate 2.4-2.5, epoxy resin of grade ED-20 14.3-14.4, plasticiser of grade EDOS 1.3-1.4, hardener Agidol of grade AF-2M 2.1-2.2, aluminium 10.9-10.5, and nitro-acid barium 16.5-16.0.

EFFECT: raised temperature of combustion of thermal source composition facilitating more deep heating and melting deposits of bottomhole zone of a reservoir, which plug channels and pores, while maintaining level of strength for compression of composition material.
