Abstract

The utility model provides an oil casing high in abrasion resistance and corrosion resistance, includes body and coupling, and the internal and external surface of body has the outer wall to ooze the layer altogether respectively and the inner wall oozes the layer altogether, and the periphery of body sets up the slip cap, and the mounting groove is seted up to the slip cap inner wall, and the mounting groove fit in sets up the crackle detector, and a plane is milled to the outside of slip cap, sets up the display screen on the plane, and the display screen is connected with the crackle detector. The utility model discloses in, the internal and external surface of body has the ion to ooze the layer altogether, and this ion oozes the layer altogether and combines together with oil jacket pipe body to there are higher superficial hardness, wearability, fatigue strength, seizure resistance, chinese people's anti -Japanese military and political college's gas and superheated steam to corrode the ability. Through the crackle detector can be timely launch the pipeline position of signal and location damaging for the maintenance personal, can also carry out some simple sealing when some not too serious cracks, the reduction of trying one's best economic loss.

Description

A kind of high abrasion rust-proof oil sleeve pipe

Technical field

This utility model belongs to petroleum works field, specifically a kind of high abrasion rust-proof oil sleeve pipe。

Background technology

At present, tubing and casing is to require the degree of depth machinery converted products high, consumption is big in petroleum engineering, and the oil-water well in oil field will use tubing and casing。But owing to oil gas usually containing the corrosive gas such as carbon dioxide and hydrogen sulfide, the tube wall of oil pipe is easily produced corrosion by these corrosive gas, constantly rubbing with tube inner wall owing to boring beam hanger in oil recovery process, and eccentric wear phenomenon and serious, thus making tube wall easily worn out, being substantially reduced the service life of oil pipe thus having a strong impact on oil production and the development benefit in oil field。The tubing and casing of the different size difference pattern that domestic and international prior art produces, its surfaces externally and internally does not all do and hardens and preservative treatment, or simply plates on single surface, is coated with anti-corrosion material process。Break and the damaged condition of pipeline are susceptible to, and maintainer is difficult to the pipeline that can find timely to go wrong, and bring very big trouble to maintenance and also result in more economic loss simultaneously。

Utility model content

This utility model provides a kind of high abrasion rust-proof oil sleeve pipe, in order to solve defect of the prior art。

This utility model is achieved by the following technical programs:

A kind of high abrasion rust-proof oil sleeve pipe, including body and box cupling, the surfaces externally and internally of body has outer wall co-penetration layer and inwall co-penetration layer respectively, the periphery of body arranges slip cap, slip cap inwall offers mounting groove, is equipped with crack detector in mounting groove, outside milling one plane of slip cap, arranging display screen in plane, display screen is connected with crack detector。

A kind of high abrasion rust-proof oil sleeve pipe as above, the periphery of described body arranges several gib block, and gib block is parallel with body, offers gathering sill inside slip cap, and gathering sill coordinates with gib block。

A kind of high abrasion rust-proof oil sleeve pipe as above, described outer wall co-penetration layer and the thickness of inwall co-penetration layer are 0.8-1.8mm。

A kind of high abrasion rust-proof oil sleeve pipe as above, is threaded engagement between described box cupling and body。

The utility model has the advantages that: in this utility model, the surfaces externally and internally of body has ion co-penetration layer, this ion co-penetration layer and tubing and casing body combine together, thus having higher case hardness, wearability, fatigue strength, seizure resistance, anti-air and superheated steam corrosive power。Signal and the pipeline location of location damage can be launched timely to maintainer by crack detector；Can also be carried out some when in the face of some less serious cracks simply to close, as far as possible decrease economic loss。

Accompanying drawing explanation

In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described below, apparently, accompanying drawing in the following describes is embodiments more of the present utility model, for those of ordinary skill in the art, under the premise not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings。

Fig. 1 is structural representation of the present utility model；Fig. 2 is the sectional view of the line A-A along Fig. 1。

Figure number marks: 1 body, and 2 outer walls are deep layer altogether, and 3 inwalls are deep layer altogether, 4 gib blocks, 5 box cuplings, 6 planes, 7 slip caps, 8 display screens, 9 gathering sills, 10 mounting grooves, 11 crack detectors。

Detailed description of the invention

For making the purpose of this utility model embodiment, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in this utility model embodiment, technical scheme in this utility model embodiment is clearly and completely described, obviously, described embodiment is a part of embodiment of this utility model, rather than whole embodiments。Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection。

A kind of high abrasion rust-proof oil sleeve pipe, as shown in the figure, including body 1 and box cupling 5, the surfaces externally and internally of body 1 has outer wall co-penetration layer 2 and inwall co-penetration layer 3 respectively, and the periphery of body 1 arranges slip cap 7, and slip cap 7 inwall offers mounting groove 10, crack detector 11 it is equipped with in mounting groove 10, outside milling one plane 6 of slip cap 7, plane 6 arranges display screen 8, and display screen 8 is connected with crack detector 11。In this utility model, the surfaces externally and internally of body has ion co-penetration layer, and this ion co-penetration layer and tubing and casing body combine together, thus having higher case hardness, wearability, fatigue strength, seizure resistance, anti-air and superheated steam corrosive power。Signal and the pipeline location of location damage can be launched timely to maintainer by crack detector；Can also be carried out some when in the face of some less serious cracks simply to close, as far as possible decrease economic loss。

Specifically, in order to make slip cap 7 sliding stability, the periphery of the body 1 described in the present embodiment arranges several gib block 4, and gib block 4 is parallel with body 1, offers gathering sill 9 inside slip cap 7, and gathering sill 9 coordinates with gib block 4。Slip cap 7 slides circuit stably, crack detection rule, it is possible to be quickly found out crack position, it is simple to repair。

Concrete, outer wall co-penetration layer 2 and the thickness of inwall co-penetration layer 3 described in the present embodiment are 0.8-1.8mm。This thickness Wear-resistant corrosion-resistant performance is best。

Further, in order to facilitate the dismounting of box cupling 5, it is threaded engagement between box cupling 5 and the body 1 described in the present embodiment。

Last it is noted that above example is only in order to illustrate the technical solution of the utility model, it is not intended to limit；Although this utility model being described in detail with reference to previous embodiment, it will be understood by those within the art that: the technical scheme described in foregoing embodiments still can be modified by it, or wherein portion of techniques feature is carried out equivalent replacement；And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment technical scheme of this utility model。
