Abstract
A kind of righting paraffin cutting oil-deflecting type rod collar, including box thread joint, body, paraffin cutting oil guide groove and oil through, it is characterized in that being provided with centre bore at the center of body, the box thread joint of symmetry it is provided with in the upper and lower of body, middle part is provided with spheroplast, spheroplast is uniformly provided with arc paraffin cutting oil guide groove, the upper and lower box thread joint reducer with spheroplast is inwardly arranged with four oil throughs, upper and lower box thread joint is provided with spanner rib.The present invention will not be worn out oil pipe, will not form the self-loopa between oil pipe and sleeve pipe of taken out oil.There is sucker rod stabilizing, to oil pipe paraffin cutting, to oil Oil Guide and the advantage of wear resistant corrosion resistant.
Description
Technical field
The present invention relates to a kind of righting paraffin cutting oil-deflecting type rod collar, overcome that existing rod collar exists is the most anti-bias
Mill, not paraffin cutting and the defect of worn out oil pipe.
Background technology
The oil pumping beam hanger box cupling of pumpingh well is all the common box cupling of only interconnection function, during moving back and forth,
Due to the change of load of pumping, sucker rod can bend, and rod collar returns mill oil pipe, often that oil pipe is worn out, makes the oil of extraction
It is returned to shaft bottom, forms circulation in well, cause oil pumper to flog a dead horse.Directly affect the normal production of oil well.
Summary of the invention
It is an object of the invention to provide a kind of righting paraffin cutting oil-deflecting type rod collar, overcome existing rod collar to exist
Not eccentric abrasion prevention, not paraffin cutting and the defect of worn out oil pipe.
The technical scheme is that and be accomplished by:
The present invention includes box thread joint, body, paraffin cutting oil guide groove and oil through, it is characterised in that set at the center of body
Having centre bore, be provided with the box thread joint of symmetry in the upper and lower of body, middle part is provided with spheroplast, in spheroplast uniformly
It is provided with arc paraffin cutting oil guide groove, the upper and lower box thread joint reducer with spheroplast is inwardly arranged with four oil throughs,
Upper and lower box thread joint is provided with spanner rib.
Paraffin cutting oil guide groove angle is set to 45 degree, and the angle between groove and groove is opposing.
Body uses and makes less than the OOCr9MoNi steel alloy of the high abrasion of oil pipe hardness, highly corrosion resistant.
The diameter of spheroplast is less than pipe aperture 10-15 millimeter.
Compared with the prior art the present invention has the advantage that
1, will not oil pipe is worn out, the self-loopa between oil pipe and sleeve pipe of taken out oil will not be formed.
2, have to sucker rod stabilizing, to oil pipe paraffin cutting, to oil water conservancy diversion and the advantage of wear resistant corrosion resistant.
3, centralizer body is spheroid, and contacting with oil pipe is tangent point contact, little to oil pipe abrasion, little to oil flow resistance.
Accompanying drawing explanation
The structural representation of accompanying drawing-present invention
1-box thread joint 2-body 3-oil through 4-paraffin cutting oil guide groove in figure
Detailed description of the invention
For the openest technical scheme, elaborated by embodiment below in conjunction with Figure of description:
The present invention includes box thread joint 1, body 2, paraffin cutting oil guide groove 4 and oil through 3, it is characterised in that in body
The heart is provided with centre bore, is provided with the box thread joint of symmetry in the upper and lower of body, and middle part is provided with spheroplast, in spheroplast
It is uniformly provided with arc paraffin cutting oil guide groove, the upper and lower box thread joint reducer with spheroplast is inwardly arranged with four logical oil
Hole, is provided with spanner rib on upper and lower box thread joint.
When applying the present invention, by the present invention, sucker rod being connected G.I.H, form sucker rod roofbolt, upper end leads to
Crossing polished rod to be connected with oil pumper, lower end is connected with oil well pump.Due to spheroplast's diameter of rod collar during oil pumping
Less than in oil pipe through 10-15 millimeter, rod string in the case of bending can centering sucker rod, make rod collar and oil pumping
Bar is the most properly functioning along oil pipe center, oily in the case of the hardness of the lubrication and rod collar that have oil is less than oil pipe hardness
Pipe is not damaged, and no matter rod collar forward or reverse under the effect of paraffin cutting oil guide groove, the wax on tubing wall can
Wipe off, and under the effect of paraffin cutting oil guide groove and oil through oil can Channel Group, the load of oil pumper will not be increased.
