Abstract
The utility model relates to oil production equipment in petroleum industries, particularly a rod positioning, centralizing and deviation preventing device which is suitable for an oil well using a pump with a rod to produce oil. The utility model has the technical scheme that the utility model comprises a rod body of a sucker rod, an upper supporting body and a lower supporting body, wherein communicating grooves are arranged on the side surfaces of the upper supporting body and the lower supporting body, the rod body of the sucker rod is positioned into the upper supporting body and the lower supporting body from the communicating grooves arranged on the side surfaces, the upper supporting body is connected and fixed with the lower supporting body through a thread, the periphery of the upper supporting body and the lower supporting body are provided with grooves, a plurality of elastic elements are installed between the bottom part of the grooves and friction blocks, and the moving distance of the friction blocks is limited by limit screws. The utility model has the advantages that after the utility model is used, when the sucker rod strokes upwards and downwards to pump oil, the rod body of the sucker rod moves upwards and downwards from the middle of the supporting bodies, the rod body of the sucker rod and the supporting bodies form a clearance fit, the friction blocks are supported on the internal wall of an oil conduit by the elastic elements, the friction blocks form an interference fit with the elastic elements, and the phenomenon of eccentric wear is avoided.
Description
One, technical field: the utility model relates to a kind of oil production equipment of petroleum industry, particularly is applicable to the bar location of the oil well of sucker rod pumping to set upright anti-deflection device.
Two, background technology: the oil field has entered the high water-cut development stage at present, and great changes have all taken place pit shaft situation and output fluidity matter etc., and sucker rod pump system works environment progressively worsens, and has aggravated the rod and tube partial-wear degree.At on-the-spot eccentric wear present situation, and the anti-eccentric wear measure of current employing mainly is to adopt oil pumping rod centering device, wear-resistant pair etc., the oil pumping rod centering device weak effect, and the cycle is short, strengthens polished rod load; The anti-eccentric wear pair of sucker rod, on-the-spot subject matter are that stuck phenomenon appears in the centralizer body and the body of rod easily, and it is ancient to be equivalent to common eccentric wear joint after stuck, and scope is promoted the use of at the scene of influence.
Three, summary of the invention: the purpose of this utility model is exactly the above-mentioned defective that exists at prior art, provides a kind of novel bar that can effectively address the above problem location to set upright anti-deflection device.
Its technical scheme is: comprise the sucker rod body of rod 1, upper support body 2 and lower support 6, have the connection groove in described upper and lower supporter 2,6 sides, make the sucker rod body of rod 1 connection groove 7 from the side insert upper and lower supporter 2,6, and by fixedly upper support body 2 and the lower support 6 of being threaded, it is characterized in that: around the described upper and lower supporter 2,6 groove 8 is set, flexible member 5 is installed between groove 8 bottoms and the brake pad 3, and between brake pad 3 and reinforcing rib groove stop screw 4 is set.
Preferable technical scheme is around the described upper and lower supporter 2,6 three groups of grooves 8 and corresponding brake pad 3 to be set, and described flexible member 5 is set to the 3-5 group; Described upper support body 2 and lower support 6 are fixing by being threaded, and make 7 one-tenth 180 degree of connection groove of their side.
Effect of the present utility model is: the sucker rod body of rod passes the two matched in clearance in the middle of supporter; Brake pad is limited in the reinforcing rib groove of supporter with dog screw, and has elastic component and make itself and supporter reinforcing rib inner groovy bottom keep certain compression distance, can not deviate from reinforcing rib under the free state; After using the utility model, when the sucker rod up-down stroke was pumped, the sucker rod body of rod moved up and down the two matched in clearance in the middle of supporter; Brake pad relies on flexible member to be supported on tube inner wall, and the two interference fit has been avoided the sucker rod partial wear phenomenon, and effect is remarkable.
Four, description of drawings:
Accompanying drawing 1 is a longitudinal sectional view of the present utility model;
Accompanying drawing 2 is A-A sectional views of the present utility model.
Five, the specific embodiment:
In conjunction with the accompanying drawings, the utility model will be further described:
Its technical scheme is: comprise the sucker rod body of rod 1, upper support body 2 and lower support 6, on described, lower support 2,6 sides have and are communicated with groove 7, the sucker rod body of rod 1 connection groove 7 is from the side freely put into, lower support 2, in the middle of 6, after the body of rod is put into, lower support is tightened in the rotation, make the side direction connection groove of lower support become 180 degree, in addition, last, lower support 2, in the reinforcing rib 9 groove 8 is set around 6, flexible member 5 is installed in the groove 8 of reinforcing rib 9 and between the brake pad 3, and the displacement of coming limiting friction piece 3 with stop screw 4, and between brake pad 3 and groove 8, leave certain compression distance.
Preferable technical scheme is around the described upper and lower supporter 2,6 three groups of grooves 8 and corresponding brake pad 3 to be set, and described flexible member 5 is set to many groups.
The course of work of the present utility model is as follows:
The utility model snaps on the sucker rod body from connecting groove, in the rotation, lower support, tighten, the connection screw thread of lower support, and make, lower groove becomes 180 degree symmetries, be lowered in the oil pipe with sucker rod then, during oil pumping the outer brake pad of supporter in the effect lower support of flexible member on tube inner wall, make the relative tube inner wall of supporter motionless, make the sucker rod body of rod be in the oil pipe center simultaneously, if the relative oil pipe of sucker rod center is offset, when the relative sucker rod body of rod of supporter slides, force power placed in the middle for one of the body of rod, simultaneously since the external diameter of supporter greater than the rod collar external diameter, so rod collar can not come in contact friction with tube inner wall, prevents side-abrasion of rod string.In addition, preservative treatment after the polishing of supporter inner headed face, friction factor reduces greatly, and its anti-wear performance improves greatly.Owing to designed suitable fit clearance between the supporter and the sucker rod body of rod, the motionless phenomenon of the stuck cunning of friction pair can not take place in oil pumping process.Simultaneously because the hardness of supporter less than the hardness of the sucker rod body of rod, can not damaged the body of rod substantially.The anti-sucker rod partial wear of this device is effective, and sucker rod substantially can eccentric wear, and pump detection period significantly improves.
After using the utility model, when the sucker rod up-down stroke was pumped, the sucker rod body of rod moved up and down the two matched in clearance in the middle of supporter; Brake pad relies on flexible member to be supported on tube inner wall, the two interference fit, the relative oil pipe of supporter is not relatively moved, when sucker rod departs from the phenomenon at oil pipe center because of the external force effect, supporter is given radial load of setting upright of the body of rod, it is not offset, and sucker rod just can not contact with tube inner wall like this, has avoided the sucker rod partial wear phenomenon.The radial load that the sucker rod skew produces only acts between the supporter and the body of rod.The utility model is simple in structure, and effect is remarkable.
