Abstract
The utility model relates to the female adapter of a kind of petroleum pipeline direct linkage type, comprise a tubular matrix, the side of described tubular matrix has one with the female threaded joint of tapering, the two ends of the internal thread of described female threaded joint have the first shoulder, the second shoulder respectively, and the tube wall external diameter that described tubular matrix comprises one section of body of described internal thread is greater than the tube wall external diameter of remainder body.The female adapter of the utility model petroleum pipeline direct linkage type is by adopting above technical scheme pipe jointing part, sleeve pipe can be realized by under the direct-connected prerequisite of internal thread, ensure that intensity and the steadiness of connection, solve current direct-connected sleeve pipe and connect unstable technical problem.
Description
Technical field
The utility model belongs to petroleum casing pipe technical field, is specifically related to the female adapter of a kind of petroleum pipeline direct linkage type.
Background technology
Sidetracked hole is the important wing for excavating potentiality of remaining oil and raising old filed recovery ratio.Sidetracked hole is exactly on the basis of original well, according to the needs of geological design, " windowing " is implemented at the certain depth of old well, a kind of boring method of meeting target zone or remaining oil enriched area is bored along planned course, it better can realize abandoned well recycling, has the features such as less investment, construction are simple, instant effect.
In sidetracked hole operation process, petroleum casing pipe generally can be used to connect, and at present, petroleum casing pipe there will be connection built on the sand and the problem of insufficient strength after being connected by internal thread or external screw thread connector, have impact on lower dark requirement, have impact on the process of sidetracked hole operation.
Utility model content
The purpose of this utility model is solve above-mentioned technical problem and provide the female adapter of a kind of petroleum pipeline direct linkage type, be intended to solve after current petroleum casing pipe is connected by common internal thread or external screw thread connector, the stable connection difference of appearance can not meet the technical problem of the needs of drillng operation.
For achieving the above object, the utility model adopts following technical scheme:
The female adapter of a kind of petroleum pipeline direct linkage type, comprise a tubular matrix, the side of described tubular matrix has one with the female threaded joint of tapering, the two ends of the internal thread of described female threaded joint have the first shoulder, the second shoulder respectively, and the tube wall external diameter that described tubular matrix comprises one section of body of described internal thread is greater than the tube wall external diameter of remainder body.
The vertical section of described one, two shoulders is trapezium structure.
Described internal thread adopts tapering to be the buttress thread of 1:16, pitch 8 teeth/in.
The female adapter of the utility model petroleum pipeline direct linkage type is by adopting above technical scheme pipe jointing part, sleeve pipe can be realized by under the direct-connected prerequisite of internal thread, ensure that intensity and the steadiness of connection, solve current direct-connected sleeve pipe and connect unstable technical problem.
Accompanying drawing explanation
Figure 1 shows that the structural representation of a kind of petroleum pipeline direct linkage type female adapter that the utility model embodiment provides.
Detailed description of the invention
Below, in conjunction with example, substantive distinguishing features of the present utility model and advantage are further described, but the utility model is not limited to listed embodiment.
Refer to shown in Fig. 1, the female adapter of a kind of petroleum pipeline direct linkage type, comprise a tubular matrix 1, the side of described tubular matrix has one with the female threaded joint 4 of tapering, the two ends of the internal thread 8 of described female threaded joint have the first shoulder 5 respectively, second shoulder 6, the tube wall external diameter that described tubular matrix 1 comprises one section of body 2 of described internal thread 8 is greater than the external diameter of the remainder body of this tubular matrix 1, thus the body making this section of large diameter body 2 have more common caliber identical thickeies comparatively speaking, and remainder body is connected by a rounding off part 3 phase transition with this large diameter body 2, the outside of described first shoulder 5 is the entrance 7 that is threaded.
By making the tube wall of body 2 form the state thickeied, by adopting the program, thus making outside pipe end, to be in thickening state, under the prerequisite not changing internal screw thread form, also can improve bonding strength, hardness, meet lower dark requirement.
It should be noted that, the structure of first and second annular inclination shoulder described is identical, as shown in Figure 1, in trapezium structure under the longitudinal section of pipe jointing part, wherein, the inner of described first annular tilting table shoulder connects with the outer end of described internal thread part, outer end connects with described annular access port, and the outer end of described second annular inclination shoulder connects with the inner of described internal thread part.
The design of first and second annular inclination shoulder described, not only ensure that tube outer wall is concordant, can arrange shouldering torgue simultaneously, ensure that connection puts in place.
As another embodiment, described internal thread adopts tapering to be the buttress thread of 1:16, pitch 8 teeth/in.Inside and outside tooth depth can adopt different depth design as required, ensures the enough intensity that is threaded, if again the length of internal thread part 8 is carried out suitable optimization, further can also increase the intensity that is threaded.
The female adapter of the utility model petroleum pipeline direct linkage type is by adopting above technical scheme pipe jointing part, sleeve pipe can be realized by under the direct-connected prerequisite of internal thread, ensure that intensity and the steadiness of connection, solve current direct-connected sleeve pipe and connect unstable technical problem.
It should be noted that, spoken of in this manual " embodiment ", " another embodiment ", " embodiment ", etc., refer to the specific features, structure or the feature that describe in conjunction with this embodiment and be included at least one embodiment of the application's generality description.Multiple place occurs that statement of the same race is not one necessarily refer to same embodiment in the description.Furthermore, when describing specific features, structure or a feature in conjunction with any embodiment, what advocate is also drop in scope of the present utility model to realize this feature, structure or feature in conjunction with other embodiments.
Although be described the utility model with reference to multiple explanatory embodiment of the present utility model here, but, should be appreciated that, those skilled in the art can design a lot of other amendment and embodiment, these amendments and embodiment will drop within spirit disclosed in the present application and spirit.
More particularly, in the scope of, accompanying drawing open in the application and claim, multiple modification and improvement can be carried out to the building block of subject combination layout and/or layout.Except the modification of carrying out building block and/or layout is with except improvement, to those skilled in the art, other purposes also will be obvious.
