Abstract

FIELD: oil and gas industry. SUBSTANCE: perforator is intended for gas and oil wells. It has shaped charges in separate hermetic body with framework for their fastening, detonating cables and initiating means. Framework for fastening charges is in the form of separate longitudinal strips with openings for head of charge which are connected by replaceable rings corresponding to diameter of perforator. Perforator ensures more unification of frameworks for perforators of various type-sizes, allows for variation of phasing of charges and density of perforations within wide limits, and also for higher strength and rigidity of frameworks. EFFECT: high efficiency.

Claims (1)

Перфоратор кумулятивный с переменным внешним диаметром для нефтяных и газовых скважин, включающий кумулятивные заряды в индивидуальном герметичном корпусе с каркасом для их крепления, детонирующие шнуры и средства инициирования, в котором каркас для крепления зарядов выполнен в виде отдельных продольных полос с отверстиями под головку заряда, соединенных посредством сменных колец, соответствующих диаметру перфоратора. Предлагаемый перфоратор позволяет повысить степень унификации каркасов для перфораторов различных типоразмеров, позволяет варьировать фазировкой зарядов и плотностью перфорации в широких пределах, а также повышает прочность и жесткость каркасов. При этом увеличивается производительность труда при изготовлении каркасов, сокращается номенклатура зарядов и элементов для их крепления.Cumulative punch with a variable external diameter for oil and gas wells, including cumulative charges in an individual sealed enclosure with a frame for their fastening, detonating cords and initiating means, in which the frame for fastening the charges is made in the form of separate longitudinal strips with holes for the charge head connected by means of interchangeable rings corresponding to the diameter of the hammer drill. The proposed punch allows you to increase the degree of unification of the frames for perforators of various sizes, allows you to vary the phasing of charges and perforation density over a wide range, and also increases the strength and rigidity of the frames. At the same time, labor productivity in the manufacture of frames increases, the nomenclature of charges and elements for their fastening is reduced.
