Abstract
A device for protecting a sucker rod from eccentric wear is provided with an upper coupling (1), an upper ball head (2), a center rod (3), a wiper block (4), a lower ball head (5) and a lower coupling (6). The utility model is characterized in that the upper ball head (2) is arranged in the inner chamber of the upper coupling (1), the lower ball head (5) is arranged in the inner chamber of the lower coupling (6), the upper ball head (2) is connected with the lower ball head (5) through the center rod (3), and the wiper block (4) is arranged on the outer side of the center rod (3). When connected onto an oil well sucker rod column, the device can protect the sucker rod column from eccentric wear.
Description
Affiliated technical field
The utility model relates to the anti-eccentric wear device of a kind of sucker rod on the oilfield, this device has last box cupling [1], upward bulb [2], center-pole [3], wiper block [4], following bulb [5], following box cupling [6] are formed, this device is connected the rod string middle and lower part, can prevents the eccentric wear of rod string.
Background technology
At present, technique known is not establish the anti-eccentric wear device of sucker rod on the oil well oil-pumping roofbolt, and in the crude oil production process, rod string is disconnected to be taken off because of the eccentric wear of rod string causes often, influences being excused from a college course the phase of oil well, has increased the cost of production of crude oil.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of sucker rod to prevent the eccentric wear device, adopts this device can prevent the eccentric wear of rod string to external oil pipe, prolongs being excused from a college course the phase of oil well, reduces the cost of production of crude oil.
The technical scheme that its technical problem that solves the utility model adopts is: adopt a kind of sucker rod to prevent the eccentric wear device, this device has last box cupling [1], upward bulb [2], center-pole [3], wiper block [4], following bulb [5], following box cupling [6] are formed, it is characterized in that: the inner chamber at last box cupling [1] is provided with bulb [2], bulb [5] under the inner chamber of box cupling [6] is provided with down, last bulb [2] is connected with following bulb [5] by center-pole [3], bulb can rotate with respect to the joint hoop, at the arranged outside wiper block [4] of center-pole [3].Wiper block [4] can rotate and pump with respect to center-pole [3]; the effect of wiper block is that joint hoop and following joint hoop are gone up in protection; this device is connected on the oil well oil-pumping roofbolt; can prevent the eccentric wear of rod string to external oil pipe; prolong being excused from a college course the phase of oil well, reduce the cost of production of crude oil.
The beneficial effects of the utility model: by field trial, the utility model compared with prior art adopts this device can prevent the eccentric wear of rod string to external oil pipe, prolongs being excused from a college course the phase of oil well, reduces the cost of production of crude oil.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described further:
Accompanying drawing is the schematic diagram of the structure embodiment of the anti-eccentric wear device of a kind of sucker rod.
Box cupling on 1. is 2. gone up bulb among the figure, 3. center-pole, and 4. wiper block 5. descends 6. times box cuplings of bulb.
The specific embodiment
In the accompanying drawings, the anti-eccentric wear device of sucker rod has last box cupling [1], upward bulb [2], center-pole [3], wiper block [4], following bulb [5], following box cupling [6] are formed, it is characterized in that: the inner chamber at last box cupling [1] is provided with bulb [2], bulb [5] under the inner chamber of box cupling [6] is provided with down, last bulb [2] is connected with following bulb [5] by center-pole [3], bulb can rotate with respect to the joint hoop, at the arranged outside wiper block [4] of center-pole [3].Wiper block [4] can rotate and pump with respect to center-pole [3]; the effect of wiper block is that joint hoop and following joint hoop are gone up in protection; this device is connected on the oil well oil-pumping roofbolt; can prevent the eccentric wear of rod string to external oil pipe; prolong being excused from a college course the phase of oil well, reduce the cost of production of crude oil.
