FIELD: process engineering.
SUBSTANCE: invention relates to shaped-charge shell-type perforators to be used for well wall perforating. Modular perforator comprises separate modules interconnected by appropriate connection means that can transmit detonation between said modules. Every said module incorporates shaped-charges and interconnected detonation channels composed by detonating cords. Every module connection assembly comprises first and second parts articulated by split joint. Transfer charge is arranged in said first part and connected via first intake charge with detonating cord. Second intake charge is arranged in second charge and connected with second detonating cord. Blank bore is made at said first part with thread at bore part to accommodate damping sleeve. Damping sleeve and transfer shaped-charge are secured inside said blank bore by the sleeve screwed to said first part.
EFFECT: higher reliability.
