Abstract
The utility model discloses the high abrasion rust-proof oil sleeve pipe that a kind of inside and outside wall surface hardness is high, abrasion resistance good, corrosion resistance is strong.A kind of high abrasion rust-proof oil sleeve pipe, comprises oil casing collar (5), tubing and casing body (1), has outer wall co-penetration layer (2) and inwall co-penetration layer (3) at the surfaces externally and internally of tubing and casing body (1).Co-penetration layer (2) and (3) can carry out oozing altogether of single surface or the different element of multi-surface as required.Multielement oozes the abrasion resistance that can improve pipe inside and outside wall according to the difference of infiltrating element altogether, anticorrosive degree and resistance to marring, thus the application life of tubing and casing is improved greatly.Body arranges screw thread (4), box cupling (5) is set simultaneously, in theory can the length of indefinite extension tubing and casing.
Description
Technical field
The utility model relates to the tubing and casing that a kind of oil extraction in oil field uses, and is specifically that a kind of inside and outside surface has tubing and casing that is wear-resisting, anticorrosive coat.
Background technology
At present, tubing and casing is the degree of depth machinery converted products requiring high, consumption large in petroleum engineering, and the oil-water well in oil field all uses tubing and casing.But owing to usually containing the corrosive gas such as carbon dioxide and hydrogen sulfide in oil gas, these corrosive gas easily produce corrosion to the tube wall of oil pipe, constantly rubbing with tube inner wall owing to boring beam hanger in oil recovery process, and eccentric wear phenomenon and serious, so just make tube wall easily worn out, greatly reduce the application life of oil pipe thus have a strong impact on oil production and the development benefit in oil field.The tubing and casing of the different pattern of different size that domestic and international prior art is produced, its surfaces externally and internally does not all do and hardens and preservative treatment, or just plates on single surface, is coated with anti-corrosion material process.
Summary of the invention
The utility model is the defect existed for prior art, the high abrasion rust-proof oil sleeve pipe that a kind of surfaces externally and internally all uses special technique to carry out processing is provided, while its surfaces externally and internally hardness is significantly improved, corrosion-resistant degree and non-oxidizability are greatly improved, resistance to marring also significantly promotes, thus to extend the oil-water well production cycle, improve oilfield economic benefit.
The utility model is achieved in that a kind of high abrasion rust-proof oil sleeve pipe, and all form the ion co-penetration layer of multielement at the surfaces externally and internally of tubing and casing, tubing and casing two ends arrange external screw thread, and one end arranges box cupling.
A kind of high abrasion rust-proof oil sleeve pipe as above, the ion co-penetration layer of wherein said multielement, be use ion multielement to ooze the surfaces externally and internally that the special elements of more than 3 kinds or 3 kinds is penetrated into tubing and casing by technology jointly altogether, make it form the ion co-penetration layer combined together with tubing and casing body at tubing and casing surfaces externally and internally.
A kind of high abrasion rust-proof oil sleeve pipe as above, wherein, is provided with external screw thread in the end of tubing and casing, puts box cupling at external screw thread peripheral hardware.
The utility model has the advantage of: the surfaces externally and internally of tubing and casing body has ion co-penetration layer, this ion co-penetration layer and tubing and casing body combine together, thus have higher case hardness, abrasion resistance, fatigue strength, seizure resistance, Chinese People's Anti-Japanese Military and Political College's gas and superheated steam corrosive power.Thus extend application life of tubing and casing, and pipe arranges screw thread, box cupling is set simultaneously, in theory can the length of indefinite extension oil pipe.
Accompanying drawing explanation
Fig. 1 is the sectional structure chart of a kind of high abrasion rust-proof oil sleeve pipe that the utility model provides.
In figure: 1. tubing and casing body, 2. outer wall co-penetration layer, 3. inwall co-penetration layer, 4. screw thread, 5. box cupling.
Detailed description of the invention
Below in conjunction with accompanying drawing, the technical solution of the utility model is further elaborated.
As shown in Figure 1, a kind of high abrasion rust-proof oil sleeve pipe, comprise tubing and casing body (1), multielement is carried out to the surfaces externally and internally of tubing and casing body (1) and oozes process altogether, obtain multielement co-penetration layer (2) and (3), multielement wherein can be selected according to oil field hole condition, and its thickness also can be selected, and range of choice is not at 0.2-2.0mm etc.
High abrasion rust-proof oil sleeve pipe be adopt special process and equipment to carry out multielement to common tubing and casing ooze process altogether.Because after process, the co-penetration layer combined together with body is defined at the surfaces externally and internally of tubing and casing, this co-penetration layer has good case hardness, abrasion resistance, fatigue strength, seizure resistance, Chinese People's Anti-Japanese Military and Political College's gas and superheated steam corrosive power, and the tubing and casing after therefore oozing process altogether has high abrasion resistance and good corrosion resistance.The end of tubing and casing body (1) is provided with external screw thread (4), arranges box cupling (5) outside external screw thread (4).When the effect of box cupling (5) is that the length of abrasion-proof oil conduit can not meet engineer applied, many high abrasion rust-proof oil sleeve pipes are coupled together, to meet engineer applied.
Claims (3)
1. a high abrasion rust-proof oil sleeve pipe, comprises tubing and casing body (1), box cupling (5) is characterized in that: have outer wall co-penetration layer (2) and inwall co-penetration layer (3) respectively at the surfaces externally and internally of tubing and casing body (1).
2. a kind of high abrasion rust-proof oil sleeve pipe as claimed in claim 1, is characterized in that: described outer wall co-penetration layer and the thickness of inwall co-penetration layer are 0.2-2mm.
3. a kind of high abrasion rust-proof oil sleeve pipe as claimed in claim 2, is characterized in that: be provided with external screw thread (4) in tubing and casing end, puts box cupling (5) at external screw thread peripheral hardware.
