Description

A kind of resistance to ground rods of oil exploitation

Technical field

This utility model relates to field of petroleum exploitation, is specifically related to a kind of resistance to ground rods of oil exploitation.

Background technology

Rod-pumped well is the most all the main oil production method in domestic and international oil field, and oil pumping polish rod is this kind of One of critical component of rod pumping system and existing oil pumping polish rod when in use, due in oil well Not having light or light-illuminating not enough, oil pumping polish rod is when putting in oil well, it is impossible to judge sucker rod Position, also cannot judge the degree of depth of sucker rod.Oil pumping polish rod as first sucker rod of rod-pumped well, First have to bear in all of sucker rod in down-hole, oil well pump and the gravity of oil well well liquid and oil pumping process and produce The load such as raw various resistances；Down-hole well liquid is back and forth occurred in big in making the cycle on one due to it Between gas, the rubber oil sea with well head to be continued rubs, hence in so that common polished rod is difficult To bear such corrosion and abrasion；It addition, along with current deep oil well, heavy oil wells and high water-cut well not Break and increase, it is also desirable to continually develop the oil pumping polish rod that the sufficiently large wear and corrosion behavior of bearing capacity is the best.

Utility model content

The purpose of this utility model is the defect for prior art and deficiency, it is provided that one can interpolate that The sucker rod degree of depth and the resistance to ground rods of wear-resisting oil exploitation.

For achieving the above object, the technical solution adopted in the utility model is: a kind of oil exploitation is with wear-resisting Polished rod, including polished rod body, mark post, wear-resisting ring and light bar；Described polished rod body is that a longitudinal direction is goed deep into The long straight-bar of cylinder within oil well, its end going deep into oil well is to expand end, the axle of this polished rod body Have the through hole of a receiving mark post to center, described mark post is arranged in this through hole, described mark post lower end It is fixed with a ball float；The total length of described ball float and mark post is equal to the length of polished rod body；Described wear-resisting ring It is arranged on polished rod body outer surface, and it is uniform along polished rod body axis direction；Described polished rod body upper end Outer surface on there is the groove of a receiving light bar, and this groove Open Side Down, described light bar is arranged on The inside of groove.

Further, described in expand end in up-small and down-big cone, and this expand end conical surface on have There is one layer of sealing gasket.

Further, described mark post cross section is triangular in shape, and three faces of this mark post are provided with scale.

Further: having a lampshade on described groove, described lampshade is embedded in by the way of engaging In groove.

Further, the junction of described lampshade and groove has sealing ring.

After using said structure, this utility model has the beneficial effect that

This utility model compared with prior art, has the advantage that simple in construction, can effectively protect Sucker rod, polished rod protruded length can be accurately identified by mark post, and wear-resisting ring can play elastic buffer effect, Prevent hard collision, thus increase the service life；Achieve the special exploitation of polished rod specific function, mainly It is when there being rod recovering system well day that blowout occurs, expands end by polished rod and carry out down-hole sealing, completely cut off well Downforce, this utility model simple in construction, when operating polished rod, it is possible to enter polished rod exposed parts length The simple and effective judgement of row, reaches the purpose accurately adjusted, and the most also has wear-resisting functions, improves and uses Life time.

Detailed description of the invention

Below in conjunction with the accompanying drawings this utility model is further described.

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with attached Figure and detailed description of the invention, be further elaborated to this utility model.Should be appreciated that this place The detailed description of the invention described, only in order to explain this utility model, is not used to limit this utility model.

Referring to Fig. 1, Fig. 2 and Fig. 3, a kind of resistance to ground rods of oil exploitation, including polished rod body 1, Mark post 4, wear-resisting ring 3 and light bar 10；Polished rod body 1 is that a longitudinal direction gos deep into the cylinder within oil well Long straight-bar, its end going deep into oil well is to expand end 7, has one at the axial centre of this polished rod body 1 Accommodating the through hole of mark post 4, mark post 4 is arranged in this through hole, and mark post 4 lower end is fixed with a ball float 6；Floating The total length of ball 6 and mark post 4 is equal to the length of polished rod body 1；Wear-resisting ring 3 is arranged on polished rod body 1 Outer surface, and it is uniform along polished rod body 1 axis direction；Have on the outer surface of polished rod body 1 upper end One groove 2 accommodating light bar 10, and the opening upwards of this groove 2, light bar 10 is arranged on the interior of groove 2 Portion.

Expand end 7 in up-small and down-big cone, and this expands and has one layer of sealing on end 7 conical surfaces Pad 5；Mark post 4 cross section is triangular in shape, and three faces of this mark post 4 are provided with scale；Have on groove 2 Having a lampshade 9, lampshade 9 is embedded in groove 2 by the way of engaging；Lampshade 9 and the connection of groove 2 Place has sealing ring 8.

During using, first the light bar 10 being used for illumination on polished rod body 1 is opened, then by light Bar body 1 inserts in oil well, and now, the interior ball float 6 of polished rod body 1 will be due to the amplitude of oil Floating, such mark post 4 is exactly the degree of depth of oil in oil well beyond the length of polished rod body 1；Polished rod body 1 On wear-resisting ring 3 anti-wear performance of polished rod body 1 can be greatly improved；The installation of light bar 10 can be played Well having, on illuminating effect, and light bar 10, lampshade 9 structure preventing oil gas from invading, this is a kind of new Technical scheme, it is simple to promote the use of.

The above, is only in order to the technical solution of the utility model to be described and unrestricted, the common skill in this area Other amendment or equivalent that the technical solution of the utility model is made by art personnel, without departing from The spirit and scope of technical solutions of the utility model, all should contain at right of the present utility model In the middle of.
