Description

The utility model relates to the elements of a perforator designed to open productive formations in oil, gas and injection wells, by which it secures the charge in the perforator and presses the detonating cord of the perforator to the charge.

The closest analogue to the utility model is a device for fixing the charge in a perforator (see, for example, the description of the invention to patent GB 2 394 762 E 21 B 43/117, published 05.05.2004), containing a cylindrical casing.

The disadvantage of the closest analogue is the insufficiently high reliability of securing the charge in the casing and attaching the detonation cord to the charge.

The objective of the utility model is to obtain a highly reliable device for installing charge in a perforator.

The technical result is expressed in increasing the reliability of the device, providing a reliable connection of the charge placed in it with the detonating cord.

The essence of the utility model is characterized by an essential feature common with the closest analogue, a cylindrical casing

and signs that differ from the closest analogue:

On the outer and inner sides of the lower part of the cylindrical casing, wedge-shaped clamps are made, on the upper part of the casing there are cone-shaped elements with an internal shape determined by the external shape of the charge placed inside, and a head with a channel whose internal size is determined by the dimensions of the detonating cord placed

in the channel of the head for connection with the charge, in the side parts of the casing and

two shaped openings are made opposite each other and covering each side of the casing and conical elements in the range from 70 to 90 relative to the vertical axis, two oblong recesses are made on the bottom of the cylindrical casing, located diametrically opposite, the lower part of the cylindrical casing is made rounded .

The essence of the utility model is illustrated in the drawing, where

figure 1 shows a General view of the device;

figure 2 shows a view of the device from below;

figure 3 shows a side view of the device from the side of the wedge-shaped retainer on the outside of the casing;

figure 4 shows the device in cross section through the wedge-shaped clamps;

figure 5 shows a device with a charge placed in it and a detonating cord with an arrangement inside the perforator;

Fig.6 shows a device with a charge placed in it and a detonating cord with an arrangement inside the perforator in section along the axis of the perforator.

The device for installing the charge contains a casing 1 of a cylindrical shape. On the outer and inner sides of the lower part of the casing 1, wedge-shaped clamps 2 and 3 are made (Figs. 1,2, 3, 4, 5, 6). On the upper part of the casing there are conical elements 4 and 5 with an internal shape determined by the external shape of the charge 6 placed inside (Figs. 5, 6). On a cone-shaped element 5, there is a head 7 with a channel 8 (Figs. 1, 2, 3,4), the inner size of which is determined by the dimensions of the detonating cord 9 (Figs. 5, 6) placed in the channel 8 of the head 7 for connection with a charge 6 ( Fig. 5,6).

In the lateral parts of the casing 1 and the conical elements 4 and 5 are made

two shaped holes 10 and 11 located opposite each other and covering each side of the casing 1 and the cone-shaped elements 4 and 5 ranging from 70 ° to 90 ° relative to the vertical axis. On the lower part of the casing 1 there are two oblong recesses 12 and 13 located diametrically opposite. The lower part of the casing 1 is rounded.

Work with the device for setting the charge is as follows.

A device for installing a charge is placed in the hole of the frame 15 of the punch with fixation by means of latches 2 (5, 6). In the channel 8 of the head 7 of the device place the detonating cord 9 (Fig.5, 6). A charge 6 is placed inside the device with a charge fixing by the clips 3. If there are several holes in the frame, devices for placing charges together with charges and a detonating cord are placed in them in the same way. After that, the frame 15c with the device for installing the charge is placed in the housing 14 of the perforator (Fig.5, 6).

By means of the head 7, the detonating cord 9 is pressed against the charge 6 with the participation of the latches 3. The execution of the lower part of the rounded casing 1 ensures the arrangement of the device for setting the charge inside the cylindrical part of the punch case 14 (Figs. 5, 6). Holes 10, 11 and recesses 12, 13 allow you to control the placement of charge 6 in the casing 1, the conical elements 4, 5, for pressing the charge 6 to the detonating cord 9 in the channel 8. The design of the device for placing the charge increases the reliability of the punch due to increase the reliability of the connection of the charge 6 with the detonating cord 9.

In addition, the holes 10, 11 and the recesses 12, 13 perform the functions of technological elements in the manufacture of a device for accommodating a charge by pressing, for example, of plastics.
