Abstract
Способ обработки призабойной зоны пласта, включающий создание избыточного давления в скважине путем воздействия на пласт газообразными продуктами горения твердотопливного заряда, отличающийся тем, что при длительном высокотемпературном воздействии на твердотопливный заряд при спуске его в скважину увеличение безопасности и эффективности обработки достигают установкой напротив пласта или около его твердотопливного заряда с жестким сгораемым картузом, причем жесткий сгораемый картуз уменьшает деформации твердотопливного заряда и препятствует его разрушению с последующим аномальным превышением давления в скважине и выделяет за счет собственного сгорания дополнительное количество энергии во время горения твердотопливного заряда, при этом в состав жесткого сгорающего картуза входят следующие компоненты, мас.%: термореактивная полимерная композиция - 30…37, пироксилиновое волокно - 18…22, взрывчатое вещество - 42…48, специальная добавка - 0…3, и сверх 100%: спирт этиловый - 10, смачиватель - 0,1.A method of treating a bottom-hole zone of a formation, including creating excess pressure in the well by exposing the formation of solid fuel charge to the formation of gaseous products of combustion, characterized in that during prolonged high-temperature exposure to the solid fuel charge when it is lowered into the well, an increase in safety and processing efficiency is achieved by installing it in front of or near the formation solid fuel charge with a rigid combustible cap, and a hard combustible cap reduces deformation of the solid charge and prevents its destruction with subsequent abnormal excess of pressure in the well and releases due to its own combustion an additional amount of energy during the combustion of a solid fuel charge, while the composition of a hard burning cap includes the following components, wt.%: thermosetting polymer composition - 30 ... 37, pyroxylin fiber - 18 ... 22, explosive - 42 ... 48, special additive - 0 ... 3, and in excess of 100%: ethyl alcohol - 10, wetting agent - 0.1.
