Description
Technical field
The present invention relates to a kind of stabilising arrangement, be specifically related to sucker rod stabilizing stabilising arrangement.
Background technology
Centralizer, also referred to as regulator, belong to cementing tool, and it is simple to manufacture, and structure is attractive in appearance, firm and durable, and uprighting force is big, overcomes former welding type centralizer and the deficiency of sealing-off easily occurs, be a kind of centralizer that can guarantee that well drilling and cementing quality.
Centralizer is of a great variety, can be divided into roller type, slide block type, automatic reverse formula etc. by structure.Different structure and the centralizer of material, it is adaptable to the oil well of dissimilar eccentric wear.Using centralizer eccentric wear-proof process key technology is position, spacing and the quantity that centralizer is installed.
Conventional centralizer, after the inclined film of centralizer body, centralizer does not reaches the effect of righting, in order to realize righting effect, it is common practice to by centralizer integral replacing, which causes relatively costly.
Summary of the invention
The technical problem to be solved is: after the inclined film of centralizer body, needs, by centralizer integral replacing, to cause relatively costly problem；Purpose is to provide the sucker rod stabilizing stabilising arrangement solving the problems referred to above.
The present invention is achieved through the following technical solutions:
Sucker rod stabilizing stabilising arrangement, including core body, is arranged on the joint at core body two ends, and the centralizer body being socketed on core body is provided with on described core body for the hard-wired limited block of centralizer body；
Described limited block includes the external screw thread being fixed on core body, and the female thread being arranged on belled body medial wall and matching with external screw thread on core body；Being additionally provided with bolt connection piece integrated with core body below described limited block, the bottom of described centralizer body is provided with the bolt hole that bolt fixes with bolt connection piece.
By limited block, bolt connection piece and the setting of bolt hole, can be more efficient and be suitable to the dismounting of centralizer body easily, thus, after centralizer body weares and teares, the replacing of centralizer body can be facilitated, it is not necessary to change core body, the most cost-effective.
Further, described centralizer body includes the belled body being fixed on core body, the wiper block being arranged on belled body, the mounting groove being arranged on wiper block, and the ball being arranged in mounting groove.Described mounting groove includes the groove for placing ball, and is arranged on groove upper surface for preventing ball abjection and the block piece making ball expose.
By the setting of said structure, the frictional force between wiper block and pipeline can be effectively reduced, it is simple to the movement of oil pick-up tube.The most effectively reduce the eccentric wear of centralizer body.
In order to be able to effectively reduce the abrasion of ball, and then the service life of prolongation ball, on described block piece, the position with ball contact is arranged to arcuate structure.
Further, the groove on described wiper block is groove.The present invention optimization by groove structure, when after the ball eccentric wear on wiper block, it is not necessary to change whole centralizer body, only need to be replaced the ball after eccentric wear, the most cost-effective.
Preferably, the external screw thread number of turns of described limited block is more than 2 circles.The fixation that could the most simultaneously realize limited block and bolt connection piece is set by this, makes the connection between centralizer body and core body more stable effectively.
The present invention compared with prior art, has such advantages as and beneficial effect:
1, the present invention is by limited block, bolt connection piece and the setting of bolt hole, can be more efficient and be suitable to the dismounting of centralizer body easily, thus, when after wiper block eccentric wear, without changing whole centralizer body, only the wiper block after eccentric wear need to be replaced, the most cost-effective；
2, the present invention setting by ball, can effectively reduce the frictional force between wiper block and pipeline, it is simple to the movement of oil pick-up tube, the most effectively reduces the eccentric wear of centralizer body；
3, the setting of arcuate structure in the present invention, can effectively reduce the abrasion of ball, and then extend the service life of ball.
