Abstract
The utility model relates to an oil pipe type continuous sucker rod centralizer, which is composed of a tubing nipple and wear resisting materials. The utility model is characterized in that the internal surface of the tubing nipple is adhered with a circular pipe which is made of the wear resisting materials, the length of the tubing nipple is 0.3 to 1.2 meters, the tubing nipple and an oil pipe are connected to a place with a slope of an oil well by a tubing coupling, and a plurality of the tubing nipples can be connected to a tubing string of the oil well. The utility model has the advantages of simple structure and convenient use, when workover operation is conducted, a worn centralizer can be replaced in time, the oil pipe is protected, and the normal production of the oil well is ensured.
Description
One, technical field
The utility model relates to the oil pumping rod centering device that a kind of oil field machinery oil is used, specifically the oil pipe formula coiled rod centralizer used of beam well or chain drive pumping unit well.
Two, background technology
At present a lot of at the well of the aboveground employing coiled rod of beam-pumping unit, the phenomenon of eccentrically worn tubing is arranged in concrete the application, what have has all ground oil pipe, causes oil pipe to miss, and influences oil well output, misses the serious closing well well workover of wanting.All there is this type of problem in the well of the not all use coiled rod of this eccentrically worn tubing phenomenon, have only the big well of hole deviation this situation just to occur, not as the sucker rod of band box cupling, eccentrically worn tubing is so general, however, the problem of coiled rod eccentrically worn tubing also in time solve, otherwise influence the popularization of coiled rod.
Three, summary of the invention
The purpose of this utility model provides a kind of oil pipe formula coiled rod centralizer, solves the problem of eccentrically worn tubing.
The technical solution of the utility model realizes in the following manner:
The utility model is made up of tubing nipple and high-abrasive material, it is characterized in that the pipe that high-abrasive material is made on tubing nipple inner surface bonding, tubing nipple is made as 0.3～1.2 meter long, be connected the gradient place of oil well with tubing coupling and oil pipe, on the tubing string of a bite oil well, can connect several.
High-abrasive material can be selected the wear-resistant plastic of rubber or polytetrafluoroethylene (PTFE) or high rigidity, uses the mould compression molding.
The utility model is simple in structure, and is easy to use, can in time change the centralizer of being ground away during workover treatment, protected oil pipe, guaranteed the ordinary production of oil well.

Five, the specific embodiment
For further disclosing the technical solution of the utility model, elaborate by embodiment below in conjunction with Figure of description:
A kind of oil pipe formula coiled rod centralizer is made up of tubing nipple 3 and high-abrasive material pipe 2.The pipe that high-abrasive material is made on tubing nipple inner surface bonding; tubing nipple is made as 0.3～1.2 meter long; be connected the gradient place of oil well with tubing coupling and oil pipe; on the tubing string of a bite oil well, can connect several centralizers; when pumping under the drive of coiled rod at oil pumper; promptly be that coiled rod also can't grind oil pipe when bending in the gradient place of oil well; protecting by centralizer; guaranteed the ordinary production of oil well; reduced the well workover number of times of oil well, the rate during production that improves oil well.
