FIELD: oil and gas industry. ^ SUBSTANCE: invention relates to oil-and-gas production field, and it is used in wells during intensification of hydrocarbon raw material extraction producing formation. Implosator includes shaped-charge perforator, shaped charge of which is fixed opposite to implemented in its casing muffled radial openings, connected to casing shaped-charge perforator one or several hollow pipes, forming implosion chambers, cable head with hoist cable. Implosator is implemented as multistage and consists of set interlaced in different amount imgagozion chamber, changing working volume of implosator. Additionally between mentioned chambers it is located at least one casing shaped-charge perforator, in which with specified sequence there are installed cumulative charges with coating or without it, able to cover radial openings in casing shaped-charge perforator with formation of cumulative jet or without it. Additionally different sets of implosion chambers are implemented with ability of interlace with different sets of shaped-charge perforator depending on well conditions. ^ EFFECT: effectiveness increasing of implosator operation. ^ 3 dwg |
