Abstract
The utility model discloses an anticorrosive ware of rod -type for well, including cylindrical shell, be equipped with the sucker rod in the cylindrical shell, the interior one end of sucker rod is equipped with the screw thread and the other end is equipped with the coupling, be equipped with the aluminium zinc alloy physically in the cylindrical shell and on being located the sucker rod, cylindrical shell outside surface is equipped with a plurality of round holes. The beneficial effects of the utility model are that, simple structure, the practicality is strong.
Description
Technical field
This utility model relates to well corrosion-preventing device, particularly a kind of well rod-type corrosion-preventing device.
Background technology
Sacrificial anode is in the application of oil well; limited due to protection domain; the most generally sacrificial anode protection domain in pipeline is about 10 times of caliber; narrow and small due to oil-water well caliber; the restriction of production environment; substantial amounts of anode can not be used, so it is not fine for using common anode effect in oil-water well.
Utility model content
The purpose of this utility model is to solve the problems referred to above, devises a kind of well rod-type corrosion-preventing device.
Realizing above-mentioned purpose the technical solution of the utility model is, a kind of well rod-type corrosion-preventing device, including cylindrical shell, it is provided with sucker rod in described cylindrical shell, in described sucker rod, one end is provided with screw thread and the other end is provided with box cupling, in described cylindrical shell and be positioned at sucker rod and be provided with alumin(i)um zinc alloy body, described cylindrical shell outer surface is provided with multiple circular hole.
The diameter of described screw thread can be 19mm, 22mm or 25mm.
The described beam hanger that pushes away is H level 20crmo.
Described cylindrical shell can be internal diameter be 19mm or 22mm, external diameter is 40mm seamless steel pipe.
Described cylindrical shell can be internal diameter be 25mm, external diameter is 51mm stainless steel tube.
Utilize a kind of well rod-type corrosion-preventing device that the technical solution of the utility model makes; add modified material in the anode; uniform dissolution in anode pit shaft can be made so that it is secondary response thing rapidly can form protecting film on pit shaft and pipe, bar surface, and because antisepsis is played in the formation of film.

In figure, 1, cylindrical shell；2, sucker rod；3, screw thread；4, box cupling；5, alumin(i)um zinc alloy body；6, circular hole.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is specifically described, as shown in Figure 1, a kind of well rod-type corrosion-preventing device, including cylindrical shell (1), sucker rod (2) it is provided with in described cylindrical shell (1), described sucker rod (2) interior one end is provided with screw thread (3) and the other end is provided with box cupling (4), and in described cylindrical shell (1) and be positioned at sucker rod (2) and be provided with alumin(i)um zinc alloy body (5), described cylindrical shell (1) outer surface is provided with multiple circular hole (6);The diameter of described screw thread (3) can be 19mm, 22mm or 25mm;Described sucker rod (2) is H level 20crmo;Described cylindrical shell (1) can be internal diameter be 19mm or 22mm, external diameter is 40mm seamless steel pipe;Described cylindrical shell (1) can be internal diameter be 25mm, external diameter is 51mm stainless steel tube.
The feature of the present embodiment is; sucker rod it is provided with in cylindrical shell; in sucker rod, one end is provided with screw thread and the other end is provided with box cupling; in cylindrical shell and be positioned at sucker rod and be provided with alumin(i)um zinc alloy body; cylindrical shell outer surface is provided with multiple circular hole, adds modified material in the anode, can make anode uniform dissolution in pit shaft; make its secondary response thing energy rapidly at pit shaft and pipe, bar surface formation protecting film, and because antisepsis is played in the formation of film.
In the present embodiment; sucker rod in cylindrical shell; in sucker rod, one end is provided with screw thread and the other end is provided with box cupling; in cylindrical shell and be positioned at sucker rod and be provided with alumin(i)um zinc alloy body; mainly alumin(i)um zinc alloy body and steam also has oxygen to form chemical reaction; thus forming protecting film, protection sucker rod plays antisepsis, replaces preservative.Cylindrical shell outer surface is provided with multiple circular hole and adsorbs some solid granules.Add modified material in the anode, anode factor uniform dissolution in pit shaft can be made so that it is secondary response thing rapidly can form protecting film on pit shaft and pipe, bar surface, and because antisepsis is played in the formation of film.
Technique scheme only embodies the optimal technical scheme of technical solutions of the utility model; some variations that some of which part may be made by those skilled in the art all embody principle of the present utility model, within belonging to protection domain of the present utility model.
