Abstract

The invention discloses a petroleum casing pipe connector. The petroleum casing pipe connector comprises a casing pipe body. An external thread is formed in the surface of the casting pipe body. The casing pipe body is connected with a first sleeve. A coupling is arranged on the first sleeve and provided with an internal thread matched with the outer thread in the surface of the casing pipe body. The first sleeve and the casting pipe body are connected in a threaded mode. A second sleeve is arranged between the first sleeve and the casing pipe body and is embedded in the casing pipe body. A connection column is vertically arranged between the second sleeve and the casing pipe body. The bottom of the connection column is fixed to the casing pipe body. The top of the connection column is connected with the second sleeve. Protection plates are arranged between the two side faces of the connection column and the second sleeve. By means of the petroleum casing pipe connector, casing pipes with the same pipe diameter can be connected, two casing pipes with different pipe diameters can also be rapidly connected, the work efficiency is greatly improved, connectivity is high, and the petroleum casing pipe connector is not prone to damage.

Description

Petroleum sleeve joint
Technical field
The present invention relates to a kind of joint, particularly a kind of petroleum sleeve joint.
Background technology
Drilling technology is in progress, require also more and more higher to well casing, specification and structure also more and more abundanter, the requirement of quality and efficiency is gone forward side by side, in prior art, when adopting joint to be coupled together by two petroleum casing pipes, usually the different situation of caliber of two petroleum casing pipes can be run into, now, staff needs the joint matched with the caliber of petroleum casing pipe with two, first be connected with petroleum casing pipe, by middle transition pipe, two joints are coupled together again, on the one hand, lose time, affect productivity effect, on the other hand, because interface is more, there is the danger of leakage of oil, casing string is the important component part in oilfield prospecting developing, the exploitation of Oil/gas Well is played an important role, casing string is the high-pressure bottle of the long number km be threaded connection by petroleum casing pipe one by one, connection of thread is joint, research shows, joint is the weakest in whole casing string, also be hold flimsy position most, therefore require that joint has higher bonding strength and good sealing performance, but, the API that current joint great majority adopt is threaded, API screw thread comprises API round thread or API buttress thread.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the problems referred to above, and providing a kind of can not only connect sleeve pipe identical for caliber, can also fast by petroleum sleeve joint that different for caliber two sleeve pipes carry out connecting.
To achieve these goals, the technical solution used in the present invention is such: petroleum sleeve joint of the present invention, comprise sleeve body, sleeve body surface is provided with external screw thread, sleeve body is connected with the first sleeve, first sleeve is provided with box cupling, box cupling is provided with the internal thread mated with sleeve body surface external screw thread, first sleeve is threaded with between sleeve body, the second sleeve is provided with between first sleeve and sleeve body, second sleeve embeds and is arranged in sleeve body, vertically joint pin is provided with between second sleeve and sleeve body, be fixed on bottom joint pin in sleeve body, joint pin top and the second sleeve connection, and be provided with backplate between joint pin two sides and the second sleeve.
Further, as a kind of concrete form of structure, backplate of the present invention is triangular form structure.
Further, as a kind of concrete form of structure, backplate of the present invention adopts steel sheet material to make.
Further, as a kind of concrete form of structure, the coated joint pin of sleeve body of the present invention is arranged.
Further, as a kind of concrete form of structure, the first sleeve of the present invention and the second sleeve connection place are provided with seal gasket.
Compared with prior art, the invention has the advantages that: sleeve pipe identical for caliber can not only connect by this petroleum sleeve joint, fast different for caliber two sleeve pipes can also be connected, substantially increase operating efficiency, and connectivity is stronger, is not easily damaged.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention; In figure: 1. sleeve body; 2. the first sleeve; 3. external screw thread; 4. the second sleeve; 5. backplate; 6. joint pin.
Detailed description of the invention
In conjunction with the accompanying drawings, the present invention is further detailed explanation, and these accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention is described in a schematic way, and therefore it only shows the formation relevant with the present invention.
The preferred embodiment of petroleum sleeve joint of the present invention as shown in Figure 1, comprise sleeve body 1, sleeve body 1 surface is provided with external screw thread 3, sleeve body 1 is connected with the first sleeve 2, first sleeve 2 is provided with box cupling, box cupling is provided with the internal thread that external screw thread 3 surperficial with sleeve body 1 mates, first sleeve 2 is threaded with between sleeve body 1, the second sleeve 4 is provided with between first sleeve 2 and sleeve body 1, second sleeve 4 embeds and is arranged in sleeve body 1, joint pin 6 is vertically provided with between second sleeve 4 and sleeve body 1, be fixed in sleeve body 1 bottom joint pin 6, joint pin 6 top is connected with the second sleeve 4, and be provided with backplate 5 between joint pin 6 two sides and the second sleeve 4, described backplate 5 is in triangular form structure, described backplate 5 adopts steel sheet material to make, the coated joint pin 6 of described sleeve body 1 is arranged, described first sleeve 2 and the second sleeve 4 junction are provided with seal gasket.
Sleeve pipe identical for caliber can not only connect by petroleum sleeve joint of the present invention, can also be connected by different for caliber two sleeve pipes fast, substantially increase operating efficiency, and connectivity is stronger, not easily be damaged, described backplate 5 is in triangular form structure, and supporting effect is better; Described backplate 5 adopts steel sheet material to make, and can better improve the application life of backplate 5; The coated joint pin 6 of described sleeve body 1 is arranged, 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, there will not be Seepage.
With above-mentioned according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, relevant staff completely can in the scope not departing from this invention technological thought, carry out various change and amendment, the technical scope of this invention is not limited to the content on manual, must determine its technical scope according to right.
