FIELD: oil and gas industry.
SUBSTANCE: plane wave explosive generator for cumulative perforators consists of imitator, a body with preliminary explosive charge with hollow lens and metal cone placed in it, the lens and the main explosive charge placed under the metal cone base, which cross-section corresponds to the base of the generator metal cone with aperture angle determined by the condition that at the moment of impact against the main charge surface the cone material has flat shape. The cone and lens are made of pressed metal powders, for example, of iron or metal ceramic impregnated with celluloid with quantity of the filling material varying within the range of 20-50%.
EFFECT: improving efficiency of hollow-cone charges.
