Abstract

This invention relates to shaped charges of perforators used for opening the productive layers in the oil and gas wells. The shaped charge has housing where there is placed a block of explosive substance with profiled cavity covered with lining, intermediate detonator, this is placed symmetrically with respect to the axis of the block of explosive substance, and a centering node for detonation wave placed round the intermediate detonator under the block of explosive substance. The centering node for detonation wave is arranged as a segment-likecharge in metal shell and intermediate, between this one and the block, explosive substance of the cylindrical charge, this is placed in a thick-wall cylinder. The segment-like charge is made of low dispersion explosive substance, and the intermediate cylindrical one - of high dispersion explosive substance with varying density in height, with its increase at coming closer to the block of explosive substance. Diameter of the cylindrical charge is not less than 1.2 of the critical one and not more than 2.5 of the critical one. This invention improves the structure of the charge and increases the piercing ability.
