Description
Technical field
The invention belongs to petroleum works field, in particular it relates to a kind of examination for simulating sucker rod-oil pipe abrasion corrosive environment
Experiment device, for the erosion corrosion behavior between laboratory condition Imitating sucker rod and oil pipe.
Background technology
With the continuous rising of water content, oil extraction in oil field was changed into present oil-in-water from former Water-In-Oil, caused to recover the oil
Lubrication between equipment is substantially reduced, and wear problem is protruded.Because oil field extracted water directly contacts oil production equipment, it will produce
Raw electrochemical corrosion.There is mutual promoting action between attrition and attack, the erosion corrosion failure of pumping unit has been greatly accelerated,
It is wherein the most serious with the erosion corrosion between sucker rod and oil pipe.Once erosion corrosion reaches certain critical value, it will result in and take out
Beam hanger breaks the serious problems such as bar, not only has the disconnected bar of salvaging, more renews the direct costs such as bar, can also produce between stop work and production
Connect loss.
At present, existing erosion corrosion test device is ring-block erosion corrosion mostly, not specifically designed for sucker rod-
Erosion corrosion test device between oil pipe.Erosion corrosion between sucker rod-oil pipe has particularity, comes firstly for abrasion
Say, be relative simple harmonic motion in sucker rod oil pumping process, between sucker rod and oil pipe, the process worn and torn equivalent to simple harmonic quantity,
In addition, Oil Field record underground sucker rod torsion is very serious, so there is relative torsion between sucker rod and oil pipe
Spin abrasion, therefore, the synthesis of abrasion simple harmonic motion abrasion and spin abrasion between sucker rod-oil pipe；Next to that corroding
Journey, oil field mining liquid is in oil well or static or flowing, for R a T be the equal of have immersion corrosion and
Erosion corrosion, in addition oil field mining liquid changed in oil well with well depth different temperatures, the design of the device takes into full account
Above-mentioned factor is arrived.
Therefore, a set of abrasion-etching problem dedicated between analog study R a T in laboratory is designed
Device it is very necessary.
The content of the invention
In order to solve the deficiency in the presence of prior art, the present invention provides a kind of simulation sucker rod-oil pipe erosion corrosion
The experimental rig of environment, the erosion corrosion mechanism for studying sucker rod-oil pipe in laboratory.
To achieve the above object, the technical solution adopted in the present invention is as follows：
The experimental rig of sucker rod-oil pipe abrasion corrosive environment is simulated, including：Liquid holding box, simple harmonic quantity abrasion mechanism, from turnery

Structure completes the simple harmonic quantity wear test between sucker rod-oil pipe by crank rocker framework, is completed by pulsating pump to sucker rod-oil
Erosion corrosion experiment between pipe；Spin abrasion mechanism by make sucker rod sample spin complete sucker rod-oil pipe between from
Revolve wear test.
Relative to prior art, the invention has the advantages that：
1st, test and design for the erosion corrosion between oil pumping in oil fields bar-oil pipe, with meeting sucker rod-oil in oil field
The synthesis that the abrasive conditions of actual conditions between pipe --- simple harmonic motion is worn and torn and spin is worn and torn.
2nd, two kinds of etch states --- immersion corrosion and erosion corrosion during energy wear Simulation.
3rd, clamping device is that scroll chuck coordinates holder structure, and sample can align effectively to fixation, guide rail and chute with
And the mechanism such as locating rod, the clamping of sample and fixation can be made more accurate.
