Description

one

The invention relates to the mining industry, in particular to the mouth

for sealing the mouth of oil and gas wells during research.

The purpose of the invention is to increase the reliability of the device, speed up its installation and increase ease of operation.

FIG. 1 shows the device a general view; in fig. 2 — node I in FIG. one; in fig. 3 is a section A-A in FIG. 2; in fig. 4 is a section BB in FIG. 3; in fig. 5 - node II in FIG.

The lubricator well survey device consists of a lubricator 1 (figs, 1 and 2) and a power post 2, designed to install the lubricator 1 on the Christmas tree-RU 3.

The lubricator 1 includes a support flange 4 and a receiving section 5 mounted thereon and a seal 6.

The power post 2 (FIGS. 1 and 2) is made of two upper 7 and 8 lower hinges connected together. At the top 7 of the power post 2, a guide roller 9 and an earring 10 are installed. At the bottom 8 of the power rack 2, a bracket 11 is fixed, in the upper part of which there is a mounting roller 12. The power bracket 13 with a pull roller is installed at the bottom of the fountain armature 3 14. Through the guide 9, the mounting 12 and the rollers 14, the geophysical cable 15 is passed. On the lower part 8 of the power rack 2 (FIG. 2) there is a nipple 16 Q of the tapered guide 17 and a cap nut 18. On the upper part 7 of the power rack 2 mounted nipple 19 with external thread bout 20 and the inner cone hole 21.

Kronschtein 11 is pivotally connected with an earring 10 with a finger 22 with a handle 23 (Fig. 3-5).

Kronschtein 11 is rigidly connected to it with sleeves 24 and 25 with supporting lugs 26 and 27, and on the side surfaces of the earring 10 there are jacks 28 and 29 with sheds 30 and 31. Bearings 26 to 27 and jacks 28 and 29 are concentrically geometric finger axes 22.

On the outer part of the sleeve 25 (figure 5) made a radial hole 32 with a through groove 33, and

the handle 23 is provided with grooves 34 with symmetrically arranged flat surfaces 35 and 36 for the passage of the grooves 34 into the through groove 33.

The width of the through groove 33 is smaller than the diameter of the radial hole 32, and the grooves 34 with flat surfaces 35 and 36 are smaller than the width of the through groove, which ensures free passage of the grooves 34 with symmetrically arranged flat surfaces 35 and 36 through the through groove 33 when the handle 23 is located along the finger 22 and the fixation of the finger 22 in the set position when the handle 23 is installed perpendicular to the geometrical axis of the finger 23.

A lubricator device is mounted and operates as follows.

A power bracket 13 is installed on the lower part of the fountain armature 3 with a tension roller 14, and a support flange 4 is installed on its upper part, after which the lower part 8 of the power rack 2 is mounted on the support flange 4 and rigidly fastened with a threaded connection with a bracket 11 mounted on it. with mounting roller 12.

Then, the upper part 7 of the power post 2 with the guide roller 9 rises manually to the installation site, which are located in the gushing wells. However, vertically mounted manually, this part is difficult because its length reaches 4 m and it weighs with the guide roller. not less than 40 kg. The upper part 7 of the force, the pillars 2 are placed on the railing of the mounting platform so that the mouths 30 and 31 and the sockets 28 and 29 are located opposite the support lugs 26 and 27 of the sleeves 24 and 25

45 of the bracket 11, after which the power rack 2 is lowered together with the earring 10 until the sockets 28 and 29 are in contact with the supporting lugs 26 and 27. As the supporting ones. the protrusions 26 and 27 of the sleeves 24 and 25 and

50 sockets 28 and 29 are located concentric with the geometric axis of the finger 22, then open in the earring 10 and in the sleeves 24 and 25 are the same. Then finger

22 is hingedly connected to an earring 10 with 55 bracket 11. In the position of the finger

22, close to the extreme one, set the handle 23 parallel to the finger so that the groove 34 of the handle

23 freely passed through the groove

33, and set the finger 22 to the extreme position. After the pin 22 is set to the extreme position, the handle 23 under its own weight is lowered into a position perpendicular to the geometric axis of the finger 22, and securely holds it with a groove 34 with flat surfaces 35 and 36 in the radial hole 2. Since the width of the through groove 33 is smaller than the diameter the radial hole 32, and the thickness of the groove 34 with symmetrically arranged flat surfaces 35 and 36 are smaller than the width of the through groove 33, the grooves 34 freely pass through the through groove 34 when the finger 22 is moved to its extreme position. When the pin 22 is mounted in the extreme position, the grooves 34 are mounted in the radial hole 32 perpendicular to the through groove 33 and the pin 22 is securely fixed in its extreme position. In this construction, the handle 23 performs the role of a lock.

Thus, the upper part 7 of the power post 2 is pivotally connected to its lower part 8. The geophysical cable 15 from the logging hoist (not shown) is passed through the slide 14, the mounting 12 and the guide roller 9 and is attached after the guide roller I. After that, the cable lift cable starts winding the geophysical cable 15 on its winch (not shown), the tension of the geophysical cable 15 occurs, and under the effect of the arising moment, the upper 7 part of the power post 2 begins to rotate around the finger 22 to its vertical position

In the process of turning the upper part 7 of the power post 2 (Figures 1 and 2), its nipple 19. centers the latter relative to the lower part 8 of the power post 2 with its internal conical hole 21 due to the conical guide part 17 formed on the nipple 16 tied to the lower part of the power rack 2.

Due to the tapered guides, the upper part 7 is centered relative to the lower part 8, and after the upper part 7 is installed, the vertical nut 18 is screwed onto the external thread 20 of the nipple 19, ensuring their fixed connection.

After that, the end of the geophysical cable 15, previously fixed on

The top of the upper part 7 of the power post 2, is released, moves down to the walkways (not shown) where the lubricator 1 is located, and passes through its seal 6 and the receiving section 5, after which the device is attached to it. Cable 15 is wound on a logging hoist winch, while the lubricator 1 with the device (not shown) rises up to the stop in the guide roller 9, hovering over the support flange 4. Thereafter, the lubricator 1 is lowered and manually fixed on the support flange 4. The lubricator The device is ready for operation. The launch and lifting operations of the instruments are carried out into the well; Demonstration of the device is carried out in reverse order.
