PASS UNIT OF DETONATION OF SHAPED-CHARGE PERFORATOR Russian patent published in 2010 - IPC E21B43/117 

FIELD: oil-and-gas production.

SUBSTANCE: unit of detonation passing contains framework, adapter connector, detonating cord, booster, booster bushing which is implemented in the form of disk and cylindrical part with axial opening for placement of booster. Adapter connector allow by longitudinal axis through internal opening with cylindrical groove for location of bushing of booster and detonating cord. Unit of detonation pass is additionally outfitted by detonating cord, booster, booster bushing, bushing of framework. Boosters are installed on detonating cords, additional bushing of booster is implemented in the form of disk and cylindrical part with axial opening for location of additional booster and located in internal opening of framework bushing from the side of cylindrical groove at the end of framework bushing for location of disk. At the butt side of adapter connector it is implemented deepening forming inside it cylindrical guideway and at the end if framework bushing contacting to butt side of adapter connector it is implemented groove with external diametre equal to diametre of deepening. Additionally outside at the middle part of framework bushing it is implemented annular thickening which creates with framework bushing one unit.

EFFECT: reliability growth of operation of unit of detonation pass of shaped-charge perforator.
