Abstract
A kind of oil pipe and deep well pump anti-corrosion anti-scale protector; belong to oil exploration equipment technical field; it is characterized in that: anticorrosion outer tube two-port and upper and lower oil-pipe external wall are fixed; anticorrosion outer sleeve inner wall is fixed with magnesium metal, aluminium-alloy pipe; magnesium metal, aluminium-alloy pipe inwall with inner trapezoidal thread groove or bar shaped vertical slot, magnesium metal, aluminium-alloy pipe inwall and the level and smooth junction of upper and lower tube inner wall.Beneficial effect is: adopt cathode protection method, is with similar products advantage in the past, and alloy material is different, and it discharges the metal ion such as magnesium and aluminium, can be hydrolyzed in water, and can have suction-operated, thus protection tube, bar and pump better.Meanwhile, project organization is reasonable, is convenient to install.Excellent electrochemical performance, drives that current potential is large, current efficiency is high, and anti-corrosion protection is effective, can meet the anticorrosion process requirement of oil pipe and deep well pump under different well depth condition.
Description
Technical field
The utility model belongs to oil exploration equipment technical field.
Background technology
All mid-later development phase is belonged at present in the most of oil field of China, due to formation water matter compatibility difference and down-hole liquid content composition difference, chemical corrosivity composition accounts for significant proportion, to oil well pipe and sucker rod serious corrosion, cause frequently changing oil pipe, beam hanger, scrappage is high, workover frequency is high, pump detection period is short, and oil development cost increases, and has a strong impact on this product of the present situation research and development of normal production run.
The product of current scene application is all the principle utilizing electrochemistry sacrificial anode and protective cathode.With active metals such as zinc, lead, magnesium as sacrificing cathode, the above-mentioned metal of weak point is not the metal that activity is the strongest, and its corrosion rate is comparatively slow, and it two is that product structure is single.
Summary of the invention
The purpose of this utility model is: provide a kind of oil pipe and deep well pump anti-corrosion anti-scale protector, and it more effectively solves oil pipe and deep well pump corrosion-resistant problem.
The technical solution of the utility model is: anticorrosion outer tube two-port and upper and lower oil-pipe external wall are fixed, anticorrosion outer sleeve inner wall is fixed with magnesium metal, corrosion of aluminium alloy pipe, magnesium, the aluminium mixing ratio of magnesium metal, aluminium-alloy pipe are 7:3, magnesium metal, corrosion of aluminium alloy inside pipe wall with inner trapezoidal thread groove or bar shaped vertical slot, magnesium metal, corrosion of aluminium alloy inside pipe wall and the level and smooth junction of upper and lower tube inner wall.
The beneficial effects of the utility model are: adopt cathode protection method; same similar products advantage is in the past; alloy material is different; alloy structure form is different, and it discharges the metal ion such as magnesium and aluminium, can be hydrolyzed in water; neutral large-area hydroxide can be formed; and this hydroxide not only has slow releasing function, and can suction-operated be had, thus protection tube, bar and pump better.Meanwhile, project organization is reasonable, is convenient to install.Excellent electrochemical performance, drives that current potential is large, current efficiency is high, and anti-corrosion protection is effective, can meet the anticorrosion process requirement of oil pipe and deep well pump under different well depth condition.
Accompanying drawing explanation
Fig. 1 is that the utility model is connected using state structure chart with oil pipe;
Fig. 2 is the utility model magnesium metal, the vertical disconnected sectional view of aluminium-alloy pipe;
Fig. 3 is the utility model magnesium metal, aluminium-alloy pipe bar shaped vertical slot structure transverse sectional view.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further:
As shown in the figure, 1 be box cupling, 2 are soldering openings, 3 are oil pipes, 4 is that anticorrosion outer tube, 5 is magnesium metals, aluminium-alloy pipe, 6 is inner trapezoidal threads.
By disconnecting in the middle part of oil pick-up tube, oil pipe is divided into two, anticorrosion outer tube 4 two-port is weldingly fixed on two fractures of oil pipe 3, oil pipe is made to become as a whole again, magnesium metal, aluminium-alloy pipe 5 is fixed in anticorrosion outer tube 4, magnesium metal, aluminium-alloy pipe 5 wall thickness is identical with oil pipe 3 wall thickness, to make magnesium metal, the junction of aluminium-alloy pipe 5 wall thickness and oil pipe 3 round mouth is level and smooth, do not affect oil pipe 3 like this to run, at magnesium metal, aluminium-alloy pipe 5 inwall is with inner trapezoidal thread groove or bar shaped vertical slot, to increase magnesium metal, aluminium-alloy pipe 5 and oil pipe 3 water and oily contact area, make its antiseptic effect better, due to favorable anti-corrosion effect, then in oil pipe 3, also seldom produce dirt, also the object of antiscale is reached.
