Description

A kind of sucker rod
Technical field
The present invention relates to a kind of metal product more particularly to a kind of sucker rods of pumping unit.
Background technology
Sucker rod is the important force transferring part in pumping unit, its upper end connection polished rod, lower end connects oil well pump, passes through oil pumping The up and down motion of polished rod is transferred to oil well pump by bar, and oil well pump is driven to carry out oil producing operation.It taps the latent power dynamics however as oil field Continuous increase, the depth of oil well pump is continuously increased, since underground environment is severe so that sucker rod aging, inclined shaft eccentric wear, corrosion The problems such as it is very serious, sucker rod service life is greatly affected, it is necessary to replace sucker rod, and existing sucker rod replacement frequency is high, Causing oil pumping cost increases.
The content of the invention
For overcome the deficiencies in the prior art, the present invention provides sucker rod, which is made of alloy material, is made Sucker rod mechanical performance, wearability, corrosion resistance, cold resistance, heat resistance greatly improved compared with existing sucker rod, sucker rod Service life greatly prolongs, and reduces the replacement number of sucker rod, reduces oil pumping cost.
In order to solve the above technical problems, the technical solution adopted in the present invention is：
A kind of sucker rod, it is characterised in that：The sucker rod is the composition metal material made of composite material Material includes following ingredient by weight percentage：
Copper 0.1~0.15%
Titanium 0.08~0.12%
Chromium 1.6~1.9%
Cobalt 0.06~0.09%
Manganese 0.8~1.2%
Silicon 0.2~0.8%
Bismuth 0.06~0.072%
Tungsten 0.03~0.05%
Rare earth metal 0.02~0.04%
Remaining is iron.
The composite material includes following ingredient by weight percentage：
Copper 0.12%
Titanium 0.09%
Chromium 1.8%
Cobalt 0.078%
Manganese 0.92%
