Abstract
The utility model provides a producing string piecing devices with locating hole of producing string way connection technology field, including producing string, connect, the through -hole, the locating hole, the inside and outside wall at producing string both ends all has the screw, it has the screw to face the wall and meditate in connecting, producing string's the outer wall screw and the inner wall of thread phase -match of joint, producing string's one end and terminal assembly are in the same place, the through -hole passes the wall of joint, the internal layout of through -hole is threaded, the locating hole is inlayed on the outer wall that connects, the medial extremity of locating hole is circular structure. The utility model discloses joint department at the pipeline increases special joint connecting device, can make two pipe connections inseparabler, suppresses the pipeline and the obscission appears in connection and use. The utility model relates to a rationally, simple structure can be applicable to the connection that various producing string said.
Description
Technical field
The joint connection in the oil extraction pipeline interconnection technique field that this utility model relates to, a kind of flow string piecing devices with hole, location.
Background technology
In oil drilling technology field, flow string is the core material of exploitation oil, relies on single flow string to be connected with each other and forms, and entire length is up to thousands of rice.Due to highly corrosive and the wet environment of underground of oil product, flow string is easily corroded damage, and its service life is by strong influence.And when oil producing operation, the phenomenon that causes that liver because heat radiation is too fast, flow string blocking can be caused even to rupture, cause very big potential safety hazard.Therefore take flow string to be effectively incubated, anti-corrosion measure particularly significant.The flow string being in underground a few km degree of depth is carried out Corrosion Repair and dredge blockage is an extremely difficult thing, not only technology is required the highest, and expense is the hugest.If be not effectively incubated flow string, anti-corrosion protection, the small-sized oil field of annual production 2000000 tons needs the flow string repaired or change just more than 100,000 every year, and in terms of the maintenance cost 500 yuan of every, this will be an astronomical figure.Traditional insulation or anti-corrosion material generally require enough thickness competence exertion effects, and this is limited by oil well casing diameter.And the junction between flow string is lacked and designs targetedly and protect by conventional vacuum, anti-corrosion material, one of the major part that corrosion occurs that causes the junction between flow string to become.Therefore the insulation of flow string, waterproof and antiseptic effect are difficult to satisfactory by traditional material.
Additionally, in technical fields such as oil transportation, coal gas conveying and heating, the insulation of associated conduit, anticorrosion etc. are also very important problems.In these technical fields, a lot of pipelines are all disposed within the environment of humidity, and after long-time use, these pipelines easily get rusty, and even result in shedding, cause serious potential safety hazard.
Therefore, developing for insulation, waterproof, the antiseptical new material of conveyance conduit and newly design, to reducing conveying cost, to improve efficiency, production safety etc. significant.
Summary of the invention
This utility model is for above-mentioned the deficiencies in the prior art, it is provided that a kind of flow string piecing devices with hole, location, by custom-designed joint connection, can make to connect between flow string more tight, be difficult to obscission occur.
This utility model is achieved through the following technical solutions, this utility model includes flow string, joint, through hole, hole, location, the inside and outside wall at flow string two ends is all threaded, the inner surface of joint is threaded, the outside wall surface screw thread of flow string matches with the inner thread of joint, one end of flow string is assembled together with joint, through hole, hole, location is arranged on joint, through hole is through the wall of joint, the inside of through hole is disposed with screw thread, hole, location is embedded in the outside wall surface of joint, the medial extremity in hole, location is arc structure, the outside dimension of joint is 112 millimeters to 113 millimeters.
Further, in this utility model, the outer surface at flow string and joint all wraps up flexible nano aeroge felt.
Compared with prior art, this utility model has the advantages that this utility model joint at pipeline, installs unique attachment means, can make to connect between flow string more tight, be difficult to obscission occur；This utility model structure is ingenious, and good looking appearance has several functions.

Detailed description of the invention
Elaborating embodiment of the present utility model below in conjunction with the accompanying drawings, embodiment, premised on technical solutions of the utility model, gives detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
Embodiment
Embodiment is as shown in Figures 1 to 4, this utility model includes flow string 1, joint 2, through hole 3, hole 4, location, the inside and outside wall at flow string 1 two ends is all threaded, the inner surface of joint 2 is threaded, the outside wall surface screw thread of flow string 1 matches with the inner thread of joint 2, one end of flow string 1 is assembled together with joint 2, through hole 3, hole 4, location is arranged on joint 2, through hole 3 is through the wall of joint 2, the inside of through hole 3 is disposed with screw thread, hole 4, location is embedded in the outside wall surface of joint 2, the medial extremity in hole 4, location is arc structure, the outside dimension of joint 2 is 112 millimeters to 113 millimeters, outer surface at flow string 1 and joint 2 all wraps up flexible nano aeroge felt.
In implementation process of the present utility model, through hole 3, hole 4, location effect under, can make to connect between flow string more tight, be difficult to that obscission occurs.
