The invention relates to oil and gas and mining industry for developing both horizontal and vertical wells, and is intended for perforation and improve the permeability in the near-wellbore area of the formation by breaking and fracturing.

The known method of perforation and treatment of bottom-hole zone of the well and the device for its implementation (patent N 2072421, MKI E 21 In 433/117 from 27.01.97, BI N3). The method is carried out cumulative perforation of the well and at the end produce implosion impact on bottom-hole zone of the well, carry out the selection of borehole fluid on the contrary, formed with the perforation process of implosion chamber, the fluid extraction increase speed. The device includes a hollow body with plugged holes and shaped charges therein, implosion chamber, an internal cavity which is connected with the inner cavity of the housing. The volume of implosion camera and housing is taken in equation (3-12):1 respectively.

The method allows to accelerate the development of wells, however, does not provide effective cleaning perforations, may be in breach of the cement lining of the column in the perforation intervals and adjacent zones, and the device that implements the method, bulky, which can hinder its use in horizontal and highly deviated wells is ins.

The known method of perforation and treatment of bottom-hole zone of the well and the device for its implementation (patent N 2178065, MKI E 21 In 433/117 from 10.01.02, BI N1). The method includes cumulative perforation of the well and at the end of implosion impact on bottom-hole zone of the well with the selection of borehole fluid on the contrary, formed with the perforation process of implosion chamber. Then produce fracturing pressure exceeding the fracture pressure. To do this, run thermogenerator. Emitted carbon dioxide in the body punch, affects created the perforation tunnels. After this break the formation energy of phase explosion. At the end of the work thermogenerator create short deep depression using implosive air chamber with a controlled valve. Perform explosive boiling of superheated metastable liquid phase and released energy affect the channels in the formation and the cracks between them. The device includes a hollow body with plugged holes and shaped charges therein, implosion chamber, an internal cavity which is connected with the inner cavity of the housing. The volume of implosion camera and housing is taken in equation (3-12):1 respectively.

Using this method entails considerable expenses is due to the complexity and bulkiness of the device.

A device and method for secondary opening of productive layers, including perforation and production of clean perforation channels simultaneously with their break through. Deep perforation of the layers applied to the device, consisting of a shaped punch and one or two of depression chambers located above and below the hammer. The volume of the upper depression cameras up to 15 or more times the amount of punch. To ensure electrical circuit electroexplosive line the upper chamber has a valve ball contact with the ability to simultaneously cross the open perforations. Lower depression Luggage has the possibility of opening with a delay in time. In cumulative perforator charges apply from CENTURIES. (patent N 2183259, MKI E 21 In 43/117, from 10.06.02 BEEP 16).

The invention provides efficient opening at a lower density perforating and cleaning of channels, allows to preserve the quality of the cement lining. However, this device is extremely cumbersome, total length must be at least 17 meters high accident rate in the works, low efficiency due to the low density of perforation.

The known method of perforation and treatment of bottom-hole zone of the well and the device for its realization, in which one suscepti the ing operation provide the perforation of the well, Stripping the layer from clogging elements and of the crust from baking perforation and fracturing pressure exceeding the fracture pressure. The internal cavity implosion chamber is connected with the inner cavity of the punch, thermogenerator connected to the drill site, which has a lattice plugged the holes. Hot gases of thermogenerator after its release mode, after work cumulative punch and implosive effects enter the body punch and through the holes in his body acting directly on the perforation tunnels in the reservoir. The volume of implosion chamber and casing perforator take in the ratio (3-12):1, respectively. To assess the nature of the impact and operation of the device it is equipped with temperature sensors and pressure, and to determine the location of the instrument in the well - locator (BI N 2162514, MKI E 21 In 43/117 from 27.01.2001). This patent is the prototype of the invention.

However, even when the specified ratio of the volumes of the chambers of implosion and punch implosive effect will be insufficient, because when the punch pressure inside the implosion chamber will increase and the pressure difference between the pressures inside and outside of it will be small and the time tweden is in the process of operation of the device at the implosion effect, very small, and therefore, the absorption will be ineffective. Unstable time mode thermogenerator and the possibility of opening the plugs in the initiation and operation of the perforator from the impact on the stub shock wave from the detonating elements of design perforator (detonating cord and shaped charges), can lead to the complete exclusion of implosive effects of processing and untimely opening of the plugs may lead to an emergency situation. The device has a complicated construction, it is not enough reliable and bulky. All the above leads to a decrease of efficiency of application of this method and device.

The essence of the invention. The invention is directed to a method and device for punching and processing borehole zone, in order to enhance the explosive processing methods both vertical and horizontal wells, wells with different curvature, with the purpose of intensification of oil and gas, as well as to reduce accidents at work.

The technical result consists in the stabilization of the treatment area of the formation, the higher quality of treatment and increase the efficiency of charges through successive launch cameras with a fixed time delay, which provides improved filtration eat ostrich properties of wellbore zone. Reducing the size of the device due to the possibility of choice of the selected volumes cameras and to select the type of charges on the composition of the fuel and the burning surface will improve safety.
