Description
верхнего зар да предыдущей ленты пропускаетс в верхнее отверстие той же ленты, закрепл етс , обходит переходную серьгу, пропускаетс в нижнее отверстие последующей ленты и также закрепл етс .the upper charge of the previous tape is passed into the upper opening of the same tape, fixed, bypasses the transitional link, passed into the lower opening of the subsequent tape and also fixed.
При таком соединении перфораторных лент отдельные группы кумул тивных зар дов ориентируютс по-разному, т. е. со сдвигом осей на некоторый угол, и создают при взрыве эффект равномерного прострела всей зоны фильтра скважины.With such a combination of perforating tapes, separate groups of cumulative charges are oriented differently, i.e., with a shift of the axes by a certain angle, and create an effect of an even shot through the entire zone of the well filter during an explosion.
Поскольку прочность соединительных серег соразмерна с прочностью лент, то при взрыве зар дов они не деформируютс , и весь стальной каркас поднимаетс на поверхность.Since the strength of the connecting earrings is commensurate with the strength of the ribbons, they do not deform when the charges explode, and the entire steel frame rises to the surface.
Предмет изобретени Subject invention
Скважинный перфоратор, содержащий головку , ленты с кумул тивными зар дами,A downhole perforator containing a head, tapes with cumulative charges,
средство инициировани и груз, отличающийс тем, что, с целью равномерного получени перфорационных отверстий в колонне обсадных труб и продуктивном пласте, преимущественно в скважинах большого диаметра , ленты снабжены переходными серьгами, выполненными в виде двух монтажных плоскостей , которые расположены одна к другой с возможностью фиксации последующей ленты вместе с зар дом на определенный угол поinitiation means and load, characterized in that, in order to uniformly obtain perforations in the casing string and reservoir, mainly in large diameter wells, the tapes are provided with transitional earrings, made in the form of two assembly planes, which are disposed of the subsequent tape along with charge at a certain angle
отношению к плоскости предыдущей.relative to the previous plane.
