Description
Technical field
This utility model relates to a kind of sucker rod anti-abrasion to be helped and takes out erection device, belongs to technical field of oil field equipment.
Background technology
In oil exploitation, sucker rod pumping is the mining type of a kind of routine, also exist sucker rod because of hole deviation, mill resistance and
The eccentric wear problem that STRESS VARIATION causes, causes the problems such as pump detection period is short, put into height, pump efficiency is low.
Utility model content
For solving above-mentioned technical problem, this utility model provides a kind of sucker rod anti-abrasion to help and takes out erection device, uses as follows
Technical scheme:
A kind of sucker rod anti-abrasion helps takes out erection device, and including steel body, steel body is hollow structure, on steel body
Being set with abrasionproof to help and take out structure, abrasionproof helps the two ends taking out structure to be torus structure, middle for ellipsoidal configuration, ellipsoidal configuration
Upper setting helps takes out hole.
Use this utility model of technique scheme compared with prior art, provide the benefit that:
Centering sucker rod, in oil pipe center, prevents sucker rod partial wear, makes sucker rod little with the friction area of oil pipe, and reduction rubs
Wipe resistance, improve pump efficiency.
Further, preferred version of the present utility model is:
Helping and taking out hole is strip hole structure, and length direction is consistent with the axis direction of steel body.
Help take out hole uniform be set to multiple.
Abrasionproof helps the two ends taking out structure to be respectively arranged with sealing structure and lower seal structure, upper sealing structure and upper sealing
Groove matches, and lower seal structure matches with lower seal groove cavity, and lower seal groove cavity is arranged on steel body, upper seal groove be arranged on
On the upper box cupling that steel body connects.
The two ends of steel body are respectively arranged with top connection and lower contact, and upper and lower joint is respectively arranged with external screw thread knot
Structure, top connection is connected with the upper box cupling with female thread structure.
The lower seal groove cavity structure arranged on steel body is placed in one end of square head structure, the other end of square head structure with
Lower contact connects.
Upper sealing structure and lower seal structure are respectively convex type structure, uniform are set to four.

Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment describes this utility model in detail:
The present embodiment, refers to the structure shown in accompanying drawing 1 to 3, and steel body 10 is hollow structure, and steel body 10 overlaps
Helping equipped with abrasionproof and take out structure 5, abrasionproof helps the two ends taking out structure 5 to be torus structure, middle for ellipsoidal configuration (similar hollow Fructus Jujubae
Nutty structure), ellipsoidal configuration arranges to help and takes out hole 6.
Helping and taking out hole 6 is strip hole structure, and the length direction of strip hole is consistent with the axis direction of steel body 10.Help and take out
Hole 6 is uniform is set to four.
Abrasionproof helps the two ends taking out structure 5 to be respectively arranged with sealing structure 501 and lower seal structure 502, upper sealing structure
501 and lower seal structure 502 be respectively most advanced and sophisticated convex shape structure (longitudinal section be triangular structure as shown in Figure 2), upper sealing
Structure 501 matches with upper seal groove 8, and lower seal structure 502 matches with lower seal groove cavity 4, the upper seal groove 8 adapted therewith
Matching with tip projection respectively with the structure of lower seal groove cavity 4, each face of upper sealing structure 501 and upper seal groove 8 is kissed completely
Closing sealing function, each face of lower seal structure 502 and lower seal groove cavity 4 fits like a glove and plays sealing function.
Lower seal groove cavity 4 is arranged on steel body 10, and upper seal groove 8 is arranged on the upper box cupling 9 being connected with steel body 10
On.
Abrasionproof helps to be taken out structure 5 and helps when sucker rod is up and take out, and reduces roofbolt resistance time descending.
The two ends of steel body 10 are respectively arranged with top connection 11 and lower contact 1, and upper and lower joint 11,1 is respectively arranged with
External thread structure, top connection 11 is connected with the upper box cupling 9 with female thread structure.
Lower seal groove cavity 4 structure arranged on steel body 10 is placed in one end of square head structure 3, square head structure 3 another
One end is connected with lower contact 1, and square head structure 3 is arranged for the ease of removing and installing.
Upper sealing structure 501 and lower seal structure 502 are respectively most advanced and sophisticated convex type structure, uniform are set to four；Also may be used
To be set to arc convex formula structure according to actual needs.
The device of this enforcement has eccentric abrasion prevention, helps the effect taking out, improving oil efficiency；Operationally, first this device is pacified
It is contained between sucker rod and sucker rod, enters well with rod string, it is possible to centering sucker rod post, prevent sucker rod and oil pipe eccentric wear,
Improve pump efficiency.
These are only the embodiment that this utility model is the most feasible, not thereby limit to right model of the present utility model
Enclosing, the equivalent structure change that all utilization description and accompanying drawing content are made, within being both contained in interest field of the present utility model.
