Description
Technical field
The present invention relates to materials processing technology field, and in particular to a kind of titanium alloy tube for oil and gas transmission and
Its preparation method.
Background technology
In the development process of petroleum gas, CO2、H2Corrosion of the gases such as S to oil pipe has turned into the main corrosion in oil field
Problem.With oil, the continuous growth of Natural Gas Demand, oil, the mining conditions of gas well deteriorate increasingly, complicated, some H2S、CO2
The successive exploitation of the harsh oil gas field of content corrosive environment high, this kind of acid is adapted in the urgent need to steel pipe manufacturing industry is developed with production
Property service condition under nonpetroleum natural gas transportation pipe.It is antiacid using the alloy material containing elements such as Ni, Cr, Mo high
Property corrosion ideal material, but because its is relatively costly, limit widely using in oil field.
The most of wax content in crude oil of China are all higher, and crude oil of the paraffin content more than 10% almost accounts for whole output crude oil
90%.When Crude Oil Transportation is carried out, due to pressure and temperature reduction, wax is separated out from crude oil and is condensed in tube wall, just forms knot
Wax phenomenon, makes oil pipe section diminish so that stifled stockaded village, especially during heavy oil transportation, wax deposition phenomenon is more serious, is having a strong impact on oil just
Often conveying.The wax deposition of oil pipeline can not only increase the energy consumption of conduit running, the safe operation of influence pipeline, but also may make
Cheng Ning run affairs therefore, carry out very big potential safety hazard to the conveyer belt of oil pipeline.Oil well production is actual to be shown, except temperature and pressure
Outward, the roughness of oil pipeline tube wall is also the key factor for influenceing wax deposition, and such as tube wall is coarse, and wax crystal is easily adhered above
Wax deposition is formed, otherwise is then not easy wax deposition.
Conventional at present solves the problems, such as that oil pipeline wax deposition has following several major ways：One is heated transportation, this to add
Heated conveying mode complex process, high energy consumption, investment is huge and security is poor, and oily transfer efficiency is extremely low.Two are added in crude oil
With pour-point depressant, anticoagulant, though this mode effect is good, the price of chemical assistant is too high, and injection throughout the year causes Crude Oil Transportation
Being substantially improved for cost, is not suitable for promoting the use of on a large scale.Three is the mode of mechanical paraffin removal, although the mode of mechanical paraffin removal into
This is low, but this reset mode can cause mechanical damage to pipeline, influences the service life of pipeline.
Accordingly, it would be desirable to develop a kind of acid proof, Wax proofing nonpetroleum natural gas transportation tubing.
The content of the invention
For the deficiencies in the prior art, the present invention provide a kind of titanium alloy tube for oil and gas transmission and
Its preparation method, solves existing oil and gas transmission pipeline steel tube perishable and cause oil transportation because of inside pipe wall wax deposition
The problem of blockage, extends the service life of feed-line, reduces maintenance and the loss for bringing that stops production, and is a kind of high-strength
Degree, corrosion-resistant, Wax proofing new titanium alloy pipe, have a good application prospect.
The titanium alloy tube intensity that the present invention is prepared is 55ksi-80ksi, is met in oil and gas transmission to tubing
The requirement of intensity；The control of alloy compositions and content makes its resistance to H at 150 DEG C2S and CO2Corrosion, extends service life；It is logical
Adjustment of formula and surface sand-blasting process are crossed, makes internal and external walls surface roughness below 3.2 μm, the function with Wax proofing.
