Installation and / or fixing of objects 12, 13 in wells 8, 9 and the operation of the devices is implemented in the following options (methods):

Option 1 (figures 1-7)

An autonomous method of installing and securing objects in wells.

At the wellhead equipped with tubing 8 and EC 9, the support connected to the object (device) 12 (Figs. 1, 5) is dropped, with spring rods 10 pressed against the walls of the tubing 8 and levers 6 made with negative jamming angles relative to the tubing walls 8 and positive jamming angles relative to the walls of the borehole or EC 9. Since the jamming angles of the levers 6 of the support relative to the walls of the tubing 8 are negative, it freely moves downward (Figs. 1, 5). When the support from the tubing 8 into the well or EC 9 (Figs. 2, 3, 4, 6), the spring-loaded levers 6 of the support moving apart are pressed against the walls of the well, for example, to EC 9, and since the wedging angles of the arms relative to the walls of EC 9 are made positive, they self-jam and prevent the support from falling down.

This is an autonomous descent of the support, opening, self-locking of the levers 6, installation and securing of the support in an autonomous manner in the well or EC 9. Descent into the well 8, 9 on the cable, rope or wire 46, installation and securing of objects in the well or in EC 9 using devices for installing and securing objects in the well are implemented in the following options:

Option 2 (Fig.8, 9)

The support (Fig. 8) connected to an object, for example, with a funnel 13 and a load, and placed in the body of the collet 28 of the drain device, in the form of a catcher, is lowered into the well or in EC 9 on cable 46 to a predetermined depth. Then, by switching on the rod displacement device 38, the support is displaced from the casing of the catcher collet 28 to the EC 9. When the support exits the casing of the catcher collet 28 (Fig. 9), the funnel 13 opens, and the spring-loaded levers 6 and the support rods 10 are made with negative jamming angles relative to elements of the catcher and positive jamming angles relative to the walls of EC 9, are moved apart and fixed in EC 9.

Option 3 (Fig.10-13)

The method of installation and fastening of the fixing device (support) in the well using a drain device or delivery head is as follows.

Before the descent into the well or EC 9, a fixing device (support) connected to or without an object (device) 12 is connected to the delivery head (Fig. 10, 12). For this, the sleeve 20 of the securing device is placed on a removable functional rod 17 of the delivery head, and the petals 23 of the collet 22 of the securing device are pressed against the grooves 18 of the functional rod 17, fixed with an elastic wire 24 by means of pins 26.

Then, the delivery head connected to the securing device is lowered into the well or EC 9. Since the angle of jamming of the retainers 24 with the walls of the tubing 8, EC 9 or couplings 42 is negative when moving down, the device freely moves to a predetermined depth.

When the design depth is reached, the delivery head connected to the securing device is lifted upward (Figs. 11, 13), as a result of which the latches 24 in contact with the sleeve 42, with the tubing walls 8 or EC 9, self-jam and move down. The petals 23 are unlocked, extended to come into contact with the walls of the couplings 42, borehole or EC 9, released from the functional rod 17 and secured in the well, for example in the coupling 42. In this case, the housing 14 of the delivery head with the functional rod 17 is removed to the surface, and the sleeve 20 s object (device) 12 are moved down under the action of their own weight and are installed between the petals 23 of the collet, preventing spontaneous release and movement of the support in the well. If there is a spring 16 (Fig. 12, 13) in the housing 14 of the delivery head, the spring-loaded functional rod 17, after the petals 23 of the collet 22 are unlocked, moves up and is installed in the housing 14 of the delivery head. Removing the fixing device to the surface is carried out by known catchers, for example a collet extractor or a releasing catcher. The presence of the telemechanical system 15 in the housing 14 of the delivery head or in the catcher allows you to control the process.

Option 4 (Fig.14-15)

Installing and securing the support (fixing device) in the well using a drain device made in the form of a catcher released with a removable collet gripper, in which the main and functional rods 37, 17 are connected to the body of the catcher collet 28 with pins 39 (Fig. 14, 15), produced as follows.

Before the descent into the well, the fishing head 11 of the support (fixing device) is connected to the catcher. To do this, by turning on the device for moving the rod 38 of the catcher (Fig. 15), the body of the collet 28 of the catcher connected to the main and functional rods 37, 17 with pins 39 is moved to its highest position, as a result of which the petals of the collet 30 are moved along the inclined planes 36 of the body of the collet 28 from axis 47 of the catcher to the periphery. Then, the support sleeve is mounted on the functional rod, the support collet petals 23 are pressed against the grooves 18 of the functional rod 17 and placed in the windows 21 of the support sleeve 20, and the support fishing head 11 is placed in the body of the catch collet 28.

Then, by turning on the rod moving device 38 (Fig. 14), the body of the catch collet 28 is moved to its lowest position. As a result of this, the catcher collet petals 30, moving along the inclined planes 36 of the collet body 28 to the catcher axis 47, capture the fishing head 11, and the support collet petals 23 pressed against the grooves 18 of the functional rod 17 are fixed by the inner walls of the sleeve 20.

Then the catcher with the support is lowered into the well to the design depth and by turning on the rod moving device 38 (Fig. 15), the functional rod 17 and the catcher collet body 28 are moved to the highest position, as a result of which the catcher collet petals 30 moving along the inclined planes 36 of the collet body 28 from the axis 47 of the catcher to the periphery, the fishing head 11 of the support is released, and the petals 23 of the support collet are removed from the windows 21 of the sleeve 20 and are moved apart when the arc moves, release the functional rod 17 and are fixed in the well, for example, in a sleeve 42. At the same time, the sleeve 20 with the object (device) 12 is moved down under the action of its own weight and installed between the petals 23 of the collet, preventing spontaneous release and movement of the support in the well.

Removing the fixing device to the surface is carried out by known catchers, for example a collet extractor or a releasing catcher. When removing the fixing device (support) from the well with the help of a catcher released with interchangeable grippers, the operations are performed in the following sequence.

The catcher released with interchangeable grippers with spread petals 30 collets lowered into the well or EC 9 until landing on the fishing head 11 (Fig, 17). Then, a current is supplied to the rod moving device 38, as a result of which the catcher collet petals 30, moving along the inclined planes 36 of the catcher collet body 28 to the device axis 47, capture the fishing head 11. The devices are lifted to the surface. The presence of the telemechanical system 15 in the housing 14 of the delivery head or in the catcher allows you to control the process.

Option 4 (Fig.16-17)

Installing and securing the support (fixing device) in the well with the help of a drain device made in the form of a catcher released with a removable collet gripper, in which the main rod 37 is connected to the petals of the catcher collet 30 with a pin 39 (Fig. 16, 17) is performed as follows. Before the descent into the well, the fishing head 11 of the support (fixing device) is connected to the catcher. To do this, by turning on the device for moving the rod 38 of the catcher (Fig.17), the petals of the collet 30 of the catcher connected to the main rod 37, pins 39, are moved to the highest position, as a result of which the petals of the collet 30 are moved along the inclined planes 36 of the body of the collet 28 from the axis 47 catcher to the periphery.

Then, the support sleeve is mounted on the functional rod, the support collet petals 23 are pressed against the grooves 18 of the functional rod 17 and placed in the windows 21 of the support sleeve 20, and the support fishing head 11 is placed in the body of the catch collet 28. Next, by turning on the rod moving device 38 (Fig. 16), the petals of the catcher collet 30 are moved to their lowest position. As a result of this, the catcher collet petals 30, moving along inclined planes 36 of the collet body 28 to the catcher axis 47, capture the fishing head 11, and the support collet petals 23 pressed against the grooves 18 of the functional rod 17 are fixed by the inner walls of the sleeve. Then the catcher with the support is lowered into the well to the design depth and by turning on the rod moving device 38 (Fig. 17), the functional rod 17 and the catcher collet petals 30 are moved to their highest position, as a result of which the catcher collet petals 30 are moved along the inclined planes 36 of the collet body 28 from the axis 47 of the catcher to the periphery, release the fishing head 11 of the support, and the petals 23 of the support collet are removed from the windows 21 of the sleeve 20 and move apart when the arc moves, release the functional rod 17 and are fixed in the borehole, for example, in couplings e 42. When the sleeve 20 with the apparatus (device) 12 are moved downward by their own weight and are installed between the petals of the collet 23, preventing spontaneous detachment and movement of the support in the well. Removing the fixing device to the surface is carried out by known catchers, for example a collet extractor or a releasing catcher.

Option 4 (Fig. 18-19)

Installing and securing the support (fixing device) in the well with the help of a drain device made in the form of a catcher released with a removable ball grip, in which the main and functional rods 37, 17 are connected to the ball catcher body 31 by pins 39 (Fig. 18, 19), produced as follows. Before the descent into the well, the fishing head 11 of the support (fixing device) is connected to the catcher. To do this, by turning on the device for moving the rod 38 of the catcher (Fig. 19), the ball catcher body 31 connected to the main and functional rods 37, 17 with pins 39 is moved to its highest position, as a result of which the grooves 32 of the ball gripper body 31 are aligned with the holes 34 of the sleeve 33 capture, and the balls 35 are recessed in the grooves 32 of the housing 31 of the capture. Then, the support sleeve is mounted on the functional rod, the support collet petals 23 are pressed against the grooves 18 of the functional rod 17 and placed in the windows 21 of the support sleeve 20, and the support fishing head 11 is placed in the ball grip housing 31 above the holes 34. Then, by turning on the rod moving device 38 ( Fig. 18) the housing 31 of the ball grip of the catcher is moved to its lowest position. As a result, the balls 35 are displaced from the grooves 32 of the capture housing 31 into the holes 34 and, moving to the axis 47, capture the support fishing head 11, are fixed by the inner walls of the capture housing 31 and prevent the support fishing head 11 from moving downward, and the support collet petals 23 are pressed to the grooves 18 of the functional rod 17, are fixed by the inner walls of the sleeve 20 of the support. Then the catcher with the support is lowered into the well to the design depth and by turning on the rod moving device 38 (Fig. 19), the main rod 37, the functional rod 17 and the ball catcher body 31 are moved to their highest position, as a result of which the grooves 32 of the body are aligned with the holes 34 of the sleeve ball capture. In this case, the balls 35 installed in the catcher sleeve 33, moving from the catcher axis 47 to the periphery, are recessed in the grooves 32 of the gripper body 28 and release the support fishing head 11, and the support collet petals 23 are removed from the windows 21 of the sleeve 20 and are moved apart during arc movement, release the functional rod 17 and are fixed in the well, for example in the sleeve 42. In this case, the sleeve 20 with the object (device) 12 is moved down under the influence of its own weight and installed between the petals 23 of the collet, preventing spontaneous unfastening and eschenie support in the well.

Removing the fixing device to the surface is carried out by known catchers, for example a collet extractor or a releasing catcher.

Option 5 (Fig.20-23)

A device for installing objects in the well works as follows. Before the descent into the well, for example in the tubing 8, of the object (device) 12, the fishing head 11 of the device 12 is placed between the petals 23 of the collet 22 (Fig.20, 22). Then, the petals 23 are compressed and fixed between each other by elastic wire 24 (Fig. 20) or cam 25 (Fig. 22) using pins 26 and traction 27. The device for installing objects in the well is ready to be lowered into the well 8. Then, the device connected to subject, lowered into the well with the clamps 24, 25 pressed against the walls of the tubing 8 (Fig. 20, 22). Since the angle of jamming of the clamps 24, 25 with the walls of the tubing 8 when moving downward is negative, the device moves freely to a predetermined depth, for example, to the landing seat 40. When the design depth is reached, the device for installing objects in the well is lifted upward (Figs. 21, 23). As a result, the latches 24, 25, made with positive jamming angles with the walls of the tubing 8 when moving upward, self-jam, are disengaged from the pins (Fig.21) or rods (Fig.23), and the windows 29 of the collet 23 are moved downward, this, the petals 23 are unlocked, extend and release the device 8. The device 8 remains at the design depth, for example on the landing saddle 40, and the device for installing objects in the well is removed to the surface. Removing the device 8 to the surface is performed by known catchers, for example a collet extractor or a catcher released with interchangeable grippers.

By turning on the rod moving device 38 (FIG. 25), the catcher collet body 28 is moved to its highest position, as a result of which the petals of the catcher collet 30, moving along the inclined planes 36 of the collet body 28, are moved apart. Then, the fishing head 11 of the support is placed between the petals of the collet 30 and the reverse polarity current is supplied to the rod moving device 38, the collet body 28 is moved to the lowermost position (Fig. 24). As a result of this operation, the collet petals 30, moving along the inclined planes 36 of the collet body 28, are shifted to the axis 47 of the catcher and capture the fishing head 11. In this case, the collet body 28 rests on the slider 44 and moves it downward relative to the bracket 43, and the spring levers 6 and rods 10, during arc movement, are pressed against the rod 1 of the support (fixing device). The device is ready to be lowered into the well. The displacement of the support from the trap and installation at the design depth of the well are carried out by applying a current of the desired polarity to the rod moving device 38 (Fig. 25). In this case, the collet body 28 moves up, and the petals of the collet 30, moving along the inclined planes 36 of the collet body 28, move apart and release the fishing head 11. Moreover, the support is smoothly extruded from the collet body 7, the slider 44 moves upward relative to the bracket 43, and the spring levers 6 and traction 10, during arc movement, are moved apart and, clinging to the walls of the well, for example to tubing 8, are finally fixed at the design depth. The catcher is released from the support and is removed to the surface. Extraction of the support on the surface is carried out by collet extractors or catchers releasing with interchangeable grippers. When removing the support using a catcher, operations are performed in the following sequence. The catcher is lowered into the well with the apart petals of the collet 30 until landing on the fishing head 11 (Fig.25). Then, current is supplied to the rod moving device 38, as a result of which the collet body 28 moves downward (FIG. 24), and the collet petals 30, moving in the windows 29 of the collet body 28 along inclined surfaces 36 to the device axis 47, capture the fishing head 11. When In this case, the collet body 28 abuts against the slider 44 and moves it downward relative to the bracket 43, and the spring-loaded levers 6 and rods 10, during arc movement, are pressed against the rod 1 of the support (fixing device). The device is raised to the surface.
