Abstract

The utility model is related to a kind of disposable setting of casing reducer union, including having female heavy caliber portion and there is externally threaded small-bore portion, the external thread part connects the outer wall in the heavy caliber portion by the first tapered transitional, and the internal thread part connects the inwall in the small-bore portion by the second tapered transitional.The utility model includes the female heavy caliber portion of tool and has externally threaded small-bore portion, very convenient to connect two kinds of sleeve pipe connections of different bores, so that convenient realize disposable setting of casing in the uncomplicated ground environment of geological condition.

Description

A kind of disposable setting of casing reducer union
Technical field
The utility model belongs to pipe joint technical field, and in particular to a kind of disposable setting of casing reducer union.
Background technology
For setting of casing, usually need to carry out several times, but can on the uncomplicated stratum of some geological conditions Setting of casing several times is not needed, only needs disposable be drilled into drill bit to design well depth, and then disposably setting of casing.And want Realize disposable setting of casing, it is necessary to two kinds of sleeve pipe connections of different bores together, but at present still not dedicated for one The secondary cased special joint of property.
Utility model content
The purpose of this utility model be solve above-mentioned technical problem and provide it is a kind of can be by two kinds of different bores Sleeve pipe connection is together with the disposable cased disposable setting of casing reducer union of realization.
To achieve the above object, the utility model is adopted the following technical scheme that:
A kind of disposable setting of casing reducer union, including have female heavy caliber portion and there is externally threaded osculum Footpath portion, the external thread part connects the outer wall in the heavy caliber portion by the first tapered transitional, and the internal thread part is by the Two tapered transitionals connect the inwall in the small-bore portion.
First tapered transitional is highly more than the height with the second tapered transitional.
The utility model is by including the female heavy caliber portion of tool and having externally threaded small-bore portion, the outer spiral shell Line portion connects the outer wall in the heavy caliber portion by the first tapered transitional, and the internal thread part is connected by the second tapered transitional The inwall in the small-bore portion is connect, it is very convenient to connect two kinds of sleeve pipe connections of different bores, so that convenient in geological condition Disposable setting of casing is realized in uncomplicated ground environment.
Brief description of the drawings
Fig. 1 illustrates the structural representation of disposable setting of casing reducer union of the present utility model.
Specific embodiment
Below, substantive distinguishing features of the present utility model and advantage are further described with reference to example, but this practicality is new Type is not limited to listed embodiment.
It is shown in Figure 1, a kind of disposable setting of casing reducer union 100, including the heavy caliber portion with internal thread 21 20 connect described big with the small-bore portion 10 with external screw thread 12, the external screw thread 12 by the first tapered transitional 13 on outer wall The circular outer wall 22 in bore portion, the internal thread 21 connects the small-bore portion by the second tapered transitional 23 on inwall Circular inner wall 11.
As a kind of preferred, the height of the height more than second tapered transitional 23 of first tapered transitional 13 Degree.
Specifically, height of the height of the internal thread part less than the external thread part.
Wherein, the total height of first tapered transitional and external thread part is less than the circular inner wall in the small-bore portion Highly.
Wherein, the total height of second tapered transitional and internal thread part is less than the circular outer wall in the heavy caliber portion Highly.
The utility model includes the female heavy caliber portion of tool and has externally threaded small-bore portion, the external thread part The outer wall in the heavy caliber portion is connected by the first tapered transitional, the internal thread part connects institute by the second tapered transitional The inwall in small-bore portion is stated, it is very convenient to connect two kinds of sleeve pipe connections of different bores, so that convenient not multiple in geological condition Disposable setting of casing, and the design that the reducer union passes through above scheme are realized in miscellaneous ground environment, intensity meets the requirements, and Facilitate processing and fabricating.
The above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art For art personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improve and Retouching also should be regarded as protection domain of the present utility model.
