Abstract
The invention relates to an anti-abrasion and pumping-assisted centralizing device for an oil pumping rod and belongs to the technical field of oil field equipment. The anti-abrasion and pumping-assisted centralizing device comprises a steel body, wherein the steel body adopts a hollow structure and is sleeved with an anti-abrasion and pumping-assisted structure; ring body structures are formed at two ends of the anti-abrasion and pumping-assisted structure, an ellipsoid structure is formed in the middle of the anti-abrasion and pumping-assisted structure, and pumping-assisted holes are formed in the ellipsoid structure. The device can be used for centralizing the oil pumping rod to an oil pipe and prevents the oil pumping rod from eccentric abrasion, so that the friction area of the oil pumping rod and the oil pipe is small, the friction resistance is reduced, and the pump efficiency is improved.
Description
Technical field
The present invention relates to a kind of sucker rod anti-abrasion help and take out erection device, belong to technical field of oil field equipment.
Background technology
In oil exploitation, sucker rod pumping is the mining type of a kind of routine, there is the eccentric wear problem that sucker rod causes because of hole deviation, mill resistance and STRESS VARIATION, causes the problems such as pump detection period is short, put into height, pump efficiency is low.
Summary of the invention
For solving above-mentioned technical problem, the present invention provides a kind of sucker rod anti-abrasion to help and takes out erection device, adopts the following technical scheme that
A kind of sucker rod anti-abrasion helps takes out erection device, including steel body, steel body is hollow structure, steel body is set with abrasionproof and helps and take out structure, abrasionproof helps the two ends taking out structure to be torus structure, middle for ellipsoidal configuration, ellipsoidal configuration arranges to help and takes out hole.
Use the present invention 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, reduces frictional resistance, improves pump efficiency.
Further, the preferred version of the present invention 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 matches with upper seal groove, lower seal structure matches with lower seal groove cavity, and lower seal groove cavity is arranged on steel body, and upper seal groove is arranged on the upper box cupling being connected with steel body.
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 thread structure, and 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, and the other end of square head structure is connected with lower contact.
Upper sealing structure and lower seal structure are respectively convex type structure, uniform are set to four.
Accompanying drawing explanation
Fig. 1 is present configuration schematic diagram.
Fig. 2 is that abrasionproof helps and takes out structural representation.
Fig. 3 is the structural representation of upper box cupling.
In figure: lower contact 1；Escape 2；Square head structure 3；Lower seal groove cavity 4；Abrasionproof helps takes out structure 5；Upper sealing structure 501, lower seal structure 502, help and take out hole 6；Upper sealing structure 7；Upper seal groove 8；Upper box cupling 9, steel body 10, top connection 11.
Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment describe in detail the present invention:
The present embodiment, refer to the structure shown in accompanying drawing 1 to 3, steel body 10 is hollow structure, it is set with abrasionproof on steel body 10 to help 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 that 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 are 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, lower seal structure 502 matches with lower seal groove cavity 4, the upper seal groove 8 adapted therewith and the structure of lower seal groove cavity 4 match with tip projection respectively, each face of upper sealing structure 501 and upper seal groove 8 fits like a glove and plays 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.
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, and 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, and the other end of square head structure 3 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；Arc convex formula structure can also be set to 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 arranged 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.
The foregoing is only the embodiment that the present invention is the most feasible, not thereby limit to the interest field of the present invention, the equivalent structure change that all utilization description of the invention and accompanying drawing content are made, within being both contained in the interest field of the present invention.
