Abstract

Invention m. used in mechanized oil production. The purpose of the invention is to increase the reliability of the installation. At the wellhead 1 of borehole 2, a truss 3 is vertically installed with rotating blocks 4,5,6,7,8 placed on it, a cable suspension 9 is passed through it. Suspension 9 is connected to polished rod 11 of the rod stubs 10 at one end 10, and 12 - with a counterweight 13. On the farm 2, parallel to the rod 11, a chain drive gear (П) 16 is installed with a leading and driven sprocket 17.18. The rollers (P) P 16 are successively interconnected by side plates. The suspension is connected via a slider 21 installed in the guides 20 with a driving P 22 P 16. The P 16 is installed in parallel guides, the upper part of which is located in the area of sprockets 17.18 in the form of semi-circles. The guides 20 are arranged vertically and together with the guides P 16 connected to the farm 2. The slider 21 is connected to the suspension 9, the K-ra is connected to P 22 by means of a connecting rod 27 installed in the slider 21. The side plates P 16 are smaller in width its diameter is P, which ensures direct contact of P P 16 with P 16 guides with a more uniform distribution of the loads acting on them. 2 Il.

Description

one

This invention relates to a technique for mechanized oil production.

The purpose of the invention is to increase the reliability of work.

On league. Figure 1 shows the conceptual diagram of the long stroke deep well pumping operation of oil wells; in fig. 2 - the same, side view.

The installation for the long stroke pumping of oil wells contains a farm 3 vertically installed at the wellhead 1 of the well 3 with rotating blocks 4–8 mounted on it, through which the cable suspension 9 is passed, connected at one end 10 to the polished rod 11 located in the well 2 columns of rods (not shown), and the other end 12 - with a counterweight 13. In farm 3, a polished rod 11 is installed parallel to the drive shaft from the engine 14 through a gearbox 15 chain transmission

16s leading and driven asterisks

17 and 18, the rollers 19 of which are successively interconnected by side plates (not shown). The suspension 9 is additionally connected via a slider 21 installed in the guides 20 to the drive roller 22 of the chain transmission 16. The chain gear 16 is mounted in additional parallel guides 23 and 24, of which the outer guides 23 are made in

the location of stars 17 and 18 of gear 16 in a farm of semi-circles

25 and 26, covering the corresponding asterisks 17 and 18.

The guides 20 of the slider 21 are arranged vertically and, together with the guides 23 and 24 of the gear 16, are connected to the truss 3. The slider 21 is directly connected to the cable suspension 9, which is connected to the drive roller 22 of the gear 16 by means of an additionally installed in the slider 21 rotary conrod pin 27, and the side plates of the gear 16 are made wider than the diameter of its rollers 19.

The rotating unit 4 can be mounted on the truss 3 with the possibility of its rotation in the idle state of the installation on the lever 28.

The installation for the long stroke deep well pumping of oil wells works as follows.

When the engine 14, the drive sprocket 17 through the chain transmission 16 leads, in turn, to movement through the connecting rod pin 27 of the slider 21.

When the slide 21 moves upward along the guides 20 through the cable suspension 9, the polished rod 11 is set in motion and together with the column rod located in the well 2 also rises up, and their counterbalance counterweight is 13 down.

When moving the slide 21 down the polished rod 11 together with the column

the boom also goes down and the counterweight goes up.

A change in the direction of movement of the slide 21 in the zone of the leading and driven sprockets G / and 18 is accompanied by the appearance in the installation of additional dynamic loads, which are largely perceived by the guides 23 and 24 of the chain transmission 1-6.

Claims (1)

The implementation of the side plates of the chain transmission 16 is less in width than the diameter of its rollers 19 and provides direct contact between the rollers 19 and guides 23 and 24 with a more uniform distribution of the loads acting on them during operation. Invention Formula An installation for long-stroke oil well pumping, containing a farm vertically mounted at the wellhead with rotating blocks placed on it, through which a cable suspension is passed, connected at one end to a polished rod located in the well of the rod string and another with a counterweight, and a chain drive with a driving and driven sprocket wheel mounted parallel to the polished rod on the truss, the rollers of which are successively connected to each other by side plates, while the suspension is additionally connected to the drive roller of the chain drive installed in the sliders, This means that, in order to increase the reliability of operation, the chain drive is installed in additional parallel guides, the upper part of which in the area of sprockets is made The semi-circles in the shape of the corresponding sprockets, the slide guides are arranged vertically and connected to the truss along with the transfer guides, the slide is directly connected to the cable suspension, which 1 is connected to the drive roller of the connecting rod, and the side-mounted transfer plates are made in width less than the diameter of its rollers. 26 22 - -18 /// /// /// / U / S / S // 7 / NU SSS fi & 1 Compiled by M.Rashepkin.
