Abstract

FIELD: equipment for perforation and treatment of bottom-hole formation zone. SUBSTANCE: device for perforation and treatment of bottom-hole formation zone has additional sealed body-air chamber with atmospheric pressure inside located between device body and the head of regular hollow-carrier jet-type perforator. This provides, with the help of one device, for performance of perforation and implosive treatment of bottom-hole formation zone, after opening of side holes in perforator body, that promotes removal from channels and fractures of formation of contaminations including those formed by remains of jet charge and jet. EFFECT: higher efficiency. 1 dwg

Предложено устройство для вскрытия и обработки призабойной зоны скважины, в котором между корпусом и головкой штатного корпусного кумулятивного перфоратора герметично размещен дополнительный корпус - воздушная камера с атмосферным давлением. Благодаря этому появляется возможность с помощью одного устройства произвести как операцию перфорации, а после раскрытия боковых отверстий в корпусе перфоратора и операцию имплозионной обработки призабойной зоны, что способствует удалению из каналов и трещин пласта загрязнений, в том числе образованных остатками кумулятивного заряда и струи.A device is proposed for opening and processing the bottom-hole zone of the well, in which an additional body is sealed between the body and the head of the standard housing cumulative perforator - an air chamber with atmospheric pressure. This makes it possible with one device to perform both the perforation operation and, after opening the side holes in the perforator case, the implosion treatment of the bottom hole zone, which helps to remove contaminants from the channels and fractures of the formation, including those formed by the cumulative charge and jet residues.
