Abstract

A DEVICE FOR REPAIRING A CIRCULAR COLSHNA, including a hollow core, at the lower end of which a head is fixed with a Dorniruch head with an expanding cone, a profile pipe with an upper stop, and installed measles above it, the cavity between which is connected to the cavity of the core, characterized in that, in order to simplify the Construction and increase its efficiency by eliminating the cause of the casing string. mounted with the possibility of axial movement along the core and spring-loaded on both sides, with the upper and lower casings of the core, equipped with fixed and movable rests, respectively, of which are self-compacting with the walls of the goat and core cuffs that are in the non-working position are located inside the covers.

Description

E)

110 The invention of ognosigs to the oil and gas-producing industry industry can be used when installing metal patches in places where oil casing strings fail to leak, as well as water and gas wells formed by corrosion, physical damage, and screw holes:; United% xIa well-known casing repair device containing a profile interrupter, a dorning head consisting of a cone, caps and a rod, measles and idrocamera ij. The closest in technical essence and the achieved result to the invention is a device for repairing and casing strings, including a conventional core, on the lower end of which is fixed a pivot and a head with an expansion cone,. a profile pipe with an upper stop and mounted measles above it consisting of upper and lower casings. the cavity between which soytsen with the cavity of the core 2. The disadvantage of these devices is the complexity of the design, and the possibility of damage to the repaired column by the bark at the points of engagement with it of the bark dies. The purpose of the invention is to simplify the design and to increase its efficiency by eliminating the damage to the casing string. It is achieved by the fact that measles is axially displaced along the core and spring-loaded on both sides, while the upper and lower core covers are provided with fixed and movable stops respectively, which form closed chambers connected to the core and core walls. The size of the self-sealing cuffs, which in the non-working position are located inside the casings. Fig. 1 shows a device, a general view; in fig. 2 - the same, at the initial moment of dornovania; . in fig. 3 is a section A-A in FIG. one; in fig. 4 is a section BB in FIG. 1. The device consists of a hollow core 1 (see FIG. 1), on which it is rigidly fixed with a movable latch. cone 2 forming a mandrel, in case 3 of which elastic diaphragm 4 is enclosed, moving sectors 5 and movable rings 6. The space bounded by body 3 and elastic diaphragm 4 represented by a hydraulic chamber 7 communicated with cavity 8 of core 1 by means of radial channels 9 Moving sectors 5 in the working position determine the outer diameter of the mandrel, which is equal to the inner diameter of the profiled pipe 1O, located above the cone 2 and interacting with the stop 11, the upper part of which is spring loaded on both sides. it has measles consisting of two, shells: the upper 12 and the lower 13, inside which are self-sealing cuffs 14 and 15 with fixed and movable parts, stops 16 and 17, which form hydraulic chambers 18 and 19, the last, and also a cavity 2O between the self-sealing cuffs 14 and 15, the communication q cavity 8 by means of radial channels 21 - 23. The lower end of the core ends with a shoe 24 with a check valve 25. The device is lowered into the well on the tubing string 26. At core 1 above and under The springs 27 and 28 are located there. The device operates as follows: it is lowered into the well in the repair zone of the casing 29 on the tubing 26, in which pressure is created by pumping a fluid which, through radggal channels 21 - 23 and 9 - chambers 7, 18 and 19 and in the cavity 20 between the sealing cuffs 14 and 15, exerts pressure simultaneously on the walls of the housings 12 and 13, sealing cuffs 14 and 15 and the diaphragm 4. The housings 12 and 13, overcoming the resistance of the springs 27 and 28, move in opposite directions until By compressing the latter, the sealing cuffs I and 15, which are straightened, abut against the casing 29, form a hydraulic chamber 30 with its wall. Under pressure of the elastic, the diaphragm 4 deforms and moves the moving sectors 5 all the way to the stop projections a / body 3 forming the mandrel and thereby displays, in working position. Profile pipe 10 under the action of u .; the force created by the casing 13, through the spring 28 to the movable stop 11 at the initial moment moves downwards, runs into the expansion cone 2 and is deformed (see Fig. 2). Occurs, as it were, jamming of the profiled core.
