Abstract
The utility model discloses a petroleum casing joint, including the sleeve pipe body, sleeve pipe body surface is equipped with the external screw thread, be connected with first sleeve on the sleeve pipe body, be equipped with the coupling on the first sleeve, be equipped with the internal thread that matches with the surperficial external screw thread of sleeve pipe body on the coupling, threaded connection between first sleeve and the sleeve pipe body, be equipped with the second sleeve between first sleeve and the sleeve pipe body, the embedding of second sleeve sets up on the sleeve pipe body, the vertical spliced pole that is equipped with between second sleeve and the sleeve pipe body, the spliced pole bottom is fixed on the sleeve pipe body, spliced pole top and second muffjoint, and be equipped with the backplate between spliced pole both sides face and the second sleeve, this petroleum casing joint not only can connect the sleeve pipe that the pipe diameter is the same, two sleeve pipes with pipe diameter different that can also be quick are connected, the work efficiency is greatly improved, and the connectivity is stronger, be difficult for receiving the damage.
Description
Technical field
This utility model relates to a kind of joint, particularly to a kind of petroleum sleeve joint.
Background technology
Well casing, in progress, is required more and more higher by drilling technology, and specification is more and more abundanter with structure, and the requirement of quality and efficiency is gone forward side by side.In prior art, when using joint to be coupled together by two petroleum casing pipes, it will usually run into the different situation of caliber of two petroleum casing pipes; now; staff needs the joint matched with the caliber of two with petroleum casing pipe, is first connected with petroleum casing pipe, then is coupled together by two joints by middle transition pipe; on the one hand; lose time, affect productivity effect, on the other hand; because seam is more, there is the danger of leakage of oil.Casing string is the important component part in oilfield prospecting developing, exploitation to Oil/gas Well plays an important role, casing string is the high-pressure bottle of the long number km being threaded connection by petroleum casing pipe one by one, threaded connection place is joint, research shows, joint be the weakest in whole casing string, also be easiest to damage position, therefore it is required that joint has higher bonding strength and preferable sealing property, but, the API that joint great majority use at present is threaded, and API screw thread includes API round thread or API buttress thread.
Utility model content
The technical problems to be solved in the utility model is: overcome the problems referred to above, it is provided that a kind of can not only be attached by sleeve pipe identical for caliber, moreover it is possible to the petroleum sleeve joint being quickly attached by two different for caliber sleeve pipes.
To achieve these goals, the technical solution adopted in the utility model is such that petroleum sleeve joint of the present utility model, including sleeve body, sleeve body surface is provided with external screw thread, connect in sleeve body and have the first sleeve, first sleeve is provided with box cupling, box cupling is provided with the female thread mated with sleeve body surface external screw thread, threaded between first sleeve and sleeve body, the second sleeve it is provided with between first sleeve and sleeve body, second sleeve embeds and is arranged in sleeve body, vertically it is provided with between second sleeve and sleeve body and is connected post, connect column bottom to be fixed in sleeve body, connect column top and the second sleeve connection, and it is provided with backplate between connection post two sides and the second sleeve.
Further, as a kind of concrete version, backplate described in the utility model is triangular form structure.
Further, as a kind of concrete version, backplate described in the utility model uses steel sheet material to make.
Further, as a kind of concrete version, sleeve body described in the utility model cladding connects post and arranges.
Further, as a kind of concrete version, at the first sleeve described in the utility model and the second sleeve connection, it is provided with seal gasket.
Compared with prior art, the utility model has the advantage of: sleeve pipe identical for caliber can not only be attached by this petroleum sleeve joint, moreover it is possible to quickly two different for caliber sleeve pipes are attached, substantially increase work efficiency, and connectivity is higher, it is not easily susceptible to damage.
Accompanying drawing explanation
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model；In figure: 1. sleeve body；2. the first sleeve；3. external screw thread；4. the second sleeve；5. backplate；6. connect post.
Detailed description of the invention
Being described in further detail this utility model presently in connection with accompanying drawing, these accompanying drawings are the schematic diagram of simplification, and basic structure of the present utility model is described the most in a schematic way, and therefore it only shows the composition relevant with this utility model.
nullThe preferred embodiment of this utility model petroleum sleeve joint as shown in Figure 1，Including sleeve body 1，Sleeve body 1 surface is provided with external screw thread 3，Connect in sleeve body 1 and have the first sleeve 2，First sleeve 2 is provided with box cupling，Box cupling is provided with the female thread mated with sleeve body 1 surface external screw thread 3，First sleeve 2 is threadeded between sleeve body 1，The second sleeve 4 it is provided with between first sleeve 2 and sleeve body 1，Second sleeve 4 embeds and is arranged in sleeve body 1，Vertically it is provided with between second sleeve 4 and sleeve body 1 and is connected post 6，Connect and be fixed in sleeve body 1 bottom post 6，Connect post 6 top to be connected with the second sleeve 4，And it is provided with backplate 5 between connection post 6 two sides and the second sleeve 4，Described backplate 5 is in triangular form structure，Described backplate 5 uses steel sheet material to make，Described sleeve body 1 cladding connects post 6 and arranges，Described first sleeve 2 and the second sleeve 4 junction are provided with seal gasket.
Sleeve pipe identical for caliber can not only be attached by petroleum sleeve joint of the present utility model, moreover it is possible to is quickly attached by two different for caliber sleeve pipes, substantially increases work efficiency, and connectivity is higher, being not easily susceptible to damage, described backplate 5 is in triangular form structure, and supporting effect is more preferable；Described backplate 5 uses steel sheet material to make, and can preferably improve the service life of backplate 5；Described sleeve body 1 cladding connects post 6 and arranges, and enhances the connectivity between component and component；Described first sleeve 2 and the second sleeve 4 junction are provided with seal gasket, good seal performance, do not have Seepage.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff completely can be in the range of without departing from this utility model technological thought, carry out various change and amendment, the content that the technical scope of this utility model is not limited in description, it is necessary to determine its technical scope according to right.
