Description
Technical field
It is the present invention relates to oil field oil pipeline de-plugging chemical cleaning field, in particular to a kind of in oil pipeline cleaning
The preparation method and application of property spontaneous heating de-plugging scale remover.
Background technique
In oil field during production run, the fouling blockage problem of oil pipeline annoyings always the normal of petroleum industry
Production.Fouling can reduce pipeline handling capacity, reduce yield, increase energy consumption equipment and generate heat and accelerate its aging.When fouling is serious
Until must just stop production when blocking oil pipeline and carry out de-plugging operation, not only consume a large amount of manpower and material resources, increase at
This, and seriously affected the normal production in oil field.Established blocking is quickly abolished, is had to the production in oil field very important
Meaning.Cause the substance of oil pipe blocking very much, common mainly has paraffin, salt dirt, corrosion dirt and sedimentation dirt.China
Most of wax content in crude oil is high, and in the actual motion of oil pipeline, most important scale forming matter is paraffin.Wax in crude oil exists
Usually exist in liquid form under formation condition.During Mining Transport, with the decline of surface temperature and pressure, crude oil is molten
Wax ability reduces, and paraffin starts crystallization and is precipitated and is attached to oil transportation inside pipe wall, and continuous precipitation and the deposition of paraffin can reduce pipeline
By diameter, ultimately form blocking.
Common method for removing blockage mainly has physical method, chemical method and biological method at present, and physical method is to utilize physics
Effect is applied to tamper and smash abolishing to it.It mainly include high-pressure water shot technology, mechanical means acoustic wave methodogy, electric field
Method, magnetic field wax control etc..Chemical method mostly uses the injection dedicated chemical reagent of de-plugging into pipeline to wash away pipeline, is disappeared with reaching dissolution
Except the purpose of tamper.Biological method is to form one layer of biology in oil pipeline wall in reproductive process using food wax microorganism to protect
Cuticula makes the easily scale forming matter such as paraffin be not easy to adhere to, to achieve the purpose that wax control.The above traditional approach exists significantly not
Foot place.Strong acid used in chemical method will cause pollution, and long-time operation meeting corrosion damage pipeline, lose more than gain.One
A little common physics method for removing blockage need to carry out halt production operation and complicated for operation more, such as high pressure water jet.And it can on-line operation side
Method is mainly also to act on when wax deposition, which is seriously formed, to be blocked little for wax control, not can solve tubing plugging troubles.Therefore, urgently
A kind of method need to be found can have an ideal wax control plugging removal effect simultaneously, and can on-line operation do not influence oil well and normally produce.
In view of the deficiencies of the prior art, the purpose of the present invention is to provide a kind of applied in industry cleaning link de-plugging scale removal
Property cleaning agent and its preparation and application, it is neutral cleaning agent that cleaning agent of the invention, which is a kind of pH, mainly for oil field
Equipment, pipeline cleaning, the cleaning agent both can understand such as: the organic deposition of wax, asphalitine long-chain can also understand nothing
Machine dirt is such as: calcium, magnesium, iron precipitating dirt, all the ingredient degradable using safety and environmental protection, main function ingredient are a kind of neutrality
Chelating agent can effectively disperse calcium and magnesium precipitating dirt precipitating, corrosion-free to equipment to human body, environment fanout free region, and there is also certain
Scale inhibition effect, convenient transportation.Make metal pipe-wall not there is a phenomenon where hydrogen embrittlement occurs using neutral de-plugging scale remover of the invention,
It is able to extend the service life of oil country tubular good.Since oil pipeline is most of all at ground or sea, than the temperature of underground oil wells
Want low, poor effect when using chemical cleaning, so allow de-plugging itself that can generate heat when preparing chemical plugging removal agent, cleaning effect
It significantly improves.
Summary of the invention
One of the objects of the present invention is to provide a kind of preparation sides that neutral spontaneous heating de-plugging scale remover is cleaned for oil pipeline
Method.
A kind of preparation method for cleaning neutral spontaneous heating de-plugging scale remover for oil pipeline, which is characterized in that this method
