Abstract

Изобретение касается перфорационной пушки с наружной пушечной трубой (1), внутри которой расположены перфораторы (10), которые воспламеняются проходящим через пушечную трубу (1) детонирующим шнуром (11) и после воспламенения пробивают пушечную трубу (1) в простреленных отверстиях (13), причем предусмотрены средства для автоматического закрывания простреленных отверстий (13). Согласно изобретению в одной форме выполнения предлагается, что средства для автоматического закрывания включают зарядные гильзы со способной набухать двухкомпонентной пеной и эти зарядные гильзы расположены в пушечной трубе (1) и разрушаются воспламененным детонирующим шнуром (11), в результате чего пена выходит из зарядных гильз, набухает и закупоривает простреленные отверстия (13). Если средства для автоматического закрывания простреленных отверстий (13) включают подвижную трубу (4), которая после прострела перемещается минимум на диаметр простреленного отверстия (13) установочным устройством, предлагается расположить подвижную трубу (4) коаксиально между перфораторами (10) и пушечной трубой (1).The invention relates to a perforating gun with an external gun tube (1), inside which perforators (10) are located, which are ignited by a detonating cord (11) passing through the gun tube (1) and, after ignition, pierce the gun tube (1) in the perforated holes (13), moreover, means are provided for automatically closing the shot holes (13). According to the invention, in one form of execution, it is proposed that the means for automatic closing include charging sleeves with a two-component foam capable of swelling, and these charging sleeves are located in the gun tube (1) and are destroyed by an ignited detonating cord (11), as a result of which the foam comes out of the charging sleeves, swells and clogs the shot holes (13). If the means for automatically closing the perforated holes (13) include a movable tube (4), which, after piercing, is moved by at least the diameter of the perforated hole (13) by the setting device, it is proposed to position the movable tube (4) coaxially between the perforators (10) and the gun tube (1 ).
