Abstract
An antiseptic, anti-scale and anti-wax protector of an oil tube and a sucker rod comprises an oil tube antiseptic, anti-scale and anti-wax protector or a sucker rod antiseptic, anti-scale and anti-wax protector. The oil tube antiseptic, anti-scale and anti-wax protector is connected onto an oil tube column in series, and the sucker rod antiseptic, anti-scale and anti-wax protector is connected onto a sucker rod column in series. The oil tube antiseptic, anti-scale and anti-wax protector comprises an inner body and an outer body, the inner body is designed to be cylindrical, and female threads or male threads are arranged on the upper portion and the lower portion. The cross section of the outer body is an isosceles trapezoid which is designed between an upper thread section and a lower thread section of the periphery of the inner body, a zinc pipe type sacrificial anode is arranged on the middle portion of annular spaces of the inner body and the outer body, 1-3 permanent strong magnet rings are arranged on two sides of the zinc pipe type sacrificial anode, and a communicating hole is arranged between the inner body and the outer body or on the outer body. The antiseptic, anti-scale and anti-wax protector can well prevent sewage from corroding the oil tube or the sucker rod, avoids scaling and wax precipitation of the oil tube and the sucker rod, is simple in structure and low in cost, and can be widely popularized and applied.
Description
Technical field
The utility model relates to the protective device of a kind of cathodic protection that prevents oil-water well oil pipe and sucker rod corrosion and scaling and wax deposition, magnetic good antiscale property, magnetic paraffin control, exactly is a kind of oil pipe and pumping rod anti-corrosive, antiscale, wax control protector.
Background technology
Because development late stage has been arrived in the oil field, crude oil water containing is very high, and some water injection wells all are to carry out produced-water reinjection in addition; So the oil pipe of oil-water well and the sucker rod of pumpingh well all are faced with the problem of the corrosion and the fouling of sewage, the oil pipe some months of some oil-water well just stops up oil pipe to tube corrosion perforation or fouling, threads off in the coupling part of sucker rod corrosion; Seriously restricting the ordinary production in oil field, the safeguard procedures of past to oil pipe are that oil pipe is advanced nitriding, or carry out anticorrosion lining and protect; Because the method complex process of two kinds of anti-corrosion anti-scales; Cost is too high, applies being restricted, and can not apply widely.
Summary of the invention
The order of the utility model provides a kind of oil pipe and pumping rod anti-corrosive, antiscale, wax control protector, and anti-method with the magnetic scale control wax control with the simple negative electrode of a kind of technology solves oil pipe and the burn into fouling of sucker rod and the problem of wax deposition.
The technical scheme of the utility model realizes in the following manner:
The utility model comprises oil pipe anti-corrosive antiscale wax control protector or pumping rod anti-corrosive antiscale wax control protector, it is characterized in that oil pipe anti-corrosive antiscale wax control protector is serially connected on the tubing string, is serially connected in beam hanger anti-corrosion anti-scale wax control protector on the rod string; Oil pipe anti-corrosive antiscale wax control protector comprises endosome and ectosome, and endosome is made as cylindrical, and the upper and lower is provided with box thread or male thread; Outer body section is an isosceles trapezoid; Design is at up and down between the thread segment of endosome periphery; Middle part at the annular space of endosome and ectosome is provided with zinc pipe formula sacrificial anode, is provided with the permanent strong magnet ring of 1-3 piece on zinc pipe formula sacrificial anode both sides, between endosome and ectosome or on ectosome, is provided with intercommunicating pore.
Pumping rod anti-corrosive antiscale wax control protector is made as cylindrical, and the upper and lower is provided with box thread, and the middle part is made as cavity, and all sides of cavity are provided with intercommunicating pore, establish zinc pipe formula sacrificial anode at the middle part of cavity, or are provided with alnico magnets on zinc pipe formula sacrificial anode both sides.
Compared with present technology the utility model has the following advantages:
1, zinc pipe formula sacrificial anode and oil pipe or oil pumping beam hanger (as negative electrode) constitute the cathodic protection loop, can prevent the corrosion of sewage to oil pipe or sucker rod well.
2, utilize strong magnetic to change dirty molecule and wax molecular structure, prevented the fouling wax deposition of oil pipe and sucker rod.
3, the utility model is simple in structure, and cost is low, can apply widely.
Description of drawings
The structural representation of Fig. 1-the utility model;
Permanent strong magnet ring 5-zinc pipe formula sacrificial anode 6-rod string (negative electrode) the 7-sleeve pipe of the anti-antiscale wax control protector 4-of 1-tubing string (negative electrode) 2-oil pipe anti-corrosive antiscale wax control protector 3-pumping rod anti-corrosive among the figure.
The specific embodiment
For further disclosing the technical scheme of the utility model, elaborate through embodiment below in conjunction with Figure of description:
The utility model comprises oil pipe anti-corrosive antiscale wax control protector 2 or pumping rod anti-corrosive antiscale wax control protector 3, it is characterized in that oil pipe anti-corrosive antiscale wax control protector is serially connected on the tubing string 1, is serially connected in beam hanger anti-corrosion anti-scale wax control protector on the rod string 6; Oil pipe anti-corrosive antiscale wax control protector comprises endosome and ectosome, and endosome is made as cylindrical, and the upper and lower is provided with box thread or male thread; Outer body section is an isosceles trapezoid; Design is at up and down between the thread segment of endosome periphery; Middle part at the annular space of endosome and ectosome is provided with zinc pipe formula sacrificial anode, is provided with the permanent strong magnet ring 4 of 1-3 piece on zinc pipe formula sacrificial anode both sides, between endosome and ectosome or on ectosome, is provided with intercommunicating pore.
When using the utility model; If pumpingh well; Oil pipe and pumping rod anti-corrosive antiscale wax control protector can be used simultaneously; Be serially connected in separately on tubing string and the rod string, zinc pipe formula sacrificial anode separately and negative electrode (oil pipe or sucker rod) form the loop of cathodic protection, are not corroded with the sacrificing protection oil pipe or the sucker rod of the sacrificial anode of zinc pipe formula sacrificial anode.Designed simultaneously permanent strong magnetic again, when oil water mixture passes through magnetic field, the molecule of various materials; Atom all produces motion under the magnetic field force effect, polar atomic deflects under the effect of magnetic field force, and zwitterion produces each other under the double action of the electrostatic force and the magnetic line of force and bumps extension; Formed neutral molecule, also just eliminated or reduced scale-forming ion, content of wax oil well has destroyed the network structure of wax molecule equally under the effect of magnetic field force; Make the wax molecule can not from crude oil, separate out knot on oil pipe or sucker rod; Play the wax control effect, water injection well only is serially connected in oil pipe anti-corrosive antiscale wax control protector on the tubing string and gets final product, and the anti-corrosion anti-scale principle is the same; If carry out the pipe inner surface anti-corrosion anti-scale; Only on the endosome of oil pipe anti-corrosive antiscale wax control protector, establish intercommunicating pore,, only on the ectosome of oil pipe anti-corrosive antiscale wax control protector, establish intercommunicating pore if it is anticorrosion to carry out oil-pipe external wall.
