Description
Technical field
The present invention relates to oil recovery machiner field, more specifically, it relates to a kind of petroleum pipeline and its application.
Background technology
With the reduction of oil reservoir energy and the rising of water content, oil field development enters high water-cut stage, due to hole deviation, sleeve pipe
The reasons such as flexural deformation cause rod-pumped well load to be continuously increased, because the well liquid corrosion lubrication state constantly reason such as deterioration causes
Pumping well pipe and sucker rod partial wear problem are increasingly severe, particularly, in current oil field development, High water cut, high salinity production
The corrosion for going out liquid more exacerbates side-abrasion of rod string and the corrosion of rod-pumped well, because the corrosion of rod-pumped well side-abrasion of rod string not only shortens
The oil well production cycle, operation well time and operating cost are added, moreover, existing antiwear and reducing friction auxiliary structure is complicated, manufacturing cost
It is high.
Therefore, publication No. provides a kind of oil well anti-corrosion righting anti-attrition pair for CN202645466U utility model, bag
Include:Box cupling body, described box cupling body interior is hollow structure, provided with internal thread;Sucker rod, described sucker rod one end are set
There is external screw thread, the other end is connected with box cupling body;Supporting positive cover, described supporting positive cover are slidably socketed in the middle part of sucker rod;
Wherein, the both ends of described box cupling body are in arc-shaped.Further, the box cupling body both ends are provided with wear-resistant layer;Wear-resistant layer
For Wear-resistant material.According to a variety of oil recovery operating modes, different bodies and Wear-resistant material are selected, can easily be had
Effect ground reduces the abrasion of flow string and rod collar, extends service life, so as to reach the purpose for reducing cost for oil production.
Petroleum pipeline of the prior art, mainly including sucker rod, box cupling, box cupling and sucker rod are provided with the both ends of sucker rod
Only realize and connect simply by screw thread, in actual use, after the screw thread between box cupling and sucker rod is damaged, spiral shell
Line Joint failure, sucker rod depart from clip, and the oil in sucker rod will outwards spray immediately, cause unnecessary waste,
The reliability of petroleum pipeline is reduced to a certain extent.
The content of the invention
In view of the shortcomings of the prior art, it is an object of the invention to provide a kind of petroleum pipeline, between sucker rod and box cupling
