DEVICE FOR PROCESSING gasdynamically punching and productive strata

摘要

The invention relates to a technique for shooting-blasting holes. It provides intensification of oil production and complex impact on the producing formation of shaped charges and the products of combustion of gunpowder charge. The task of creating utility model are more efficient impact on oil and gas bearing formations propellant gases due to sequential activation cumulative and propellant charge, and an increase rate of combustion of gunpowder charge and increasing the pressure in the producing formation zone. Solving these problems is reached due to the fact that the device for perforating and gas-dynamic treatment of the producing formation, lowered into the well on the logging cable is composed of a powder charge from the central channel within which the chassis fitted shaped charges connected detonating cord with the explosive cartridge that conductor electrically connected to the logging cable. body function performs a powder charge adapted with holes opposite which on the frame mounted the shaped charges, the frame is fixed against radial and axial movement in the central channel of the propellant charge, and on top and bottom of the installed additional powder charges made with one or more non-through cavities filled with a high-energy composite material. Powder charge between the holes made with the grooves filled with the composite material in a high-energy high-quality composite material using nano-size aluminum powder. The diameter of the holes formed in the powder charge greater than the diameter of cumulative jets. Holes are made in the powder charge expanding away from the shaped charges. For fixing the carcass of the radial and axial movement on the frame belongs to a projection formed groove within the central channel of gunpowder charge. Lower additional propellant charge closed fairing. Lower additional propellant charge and a fairing formed with holes and fastened to the stud nut fixed frame bottom. The fairing is made of the same material as the powder charge. Upper additional propellant charge is formed with an opening through which the wire is connected through the logging cable with the tip, wherein the wire pressing upper retainer mounted additional propellant charge to the propellant charge. Shaped explosive charges and cartridge are sealed. To activate the shaped charges apply water-resistant detonating cords. A non-through cavity in the additional propellant charge may be formed annular. Non-through cavity in the additional propellant charge may be formed a circular shape. Non-through cavity in the additional propellant charge can not be performed for example circular shape oval, triangular, rectangular or combined.; 1. p-t-p ly, head 14. n-ing, ill.6.
