Abstract

It the utility model is related to a kind of taper sand-proof sieve tube, including wrapping wire, the rib that is arranged circumferentially along the wrapping wire, the wrapping wire wind the rib and form overall taper.To judge that whether disorderly closedown provides reference to wire drawing machine, ensure that the order of production, also ensure that production safety.The sand-proof sieve tube installation resistance of taper is small, and one end size away from ground is small, and structural strength is big, and bearing structure is more reasonable.

Description

A kind of taper sand-proof sieve tube

Technical field

Drilling well sand control equipment production field is the utility model is related to, in particular to a kind of taper sand-proof sieve tube.

Background technology

Sand-proof sieve tube is frequently utilized for sand prevention in petroleum drilling and mining, but resistance is larger when mounted for cylindric middle sand-proof sieve tube, In engineering there is problem in operation, and because bigger pressure is usually born in one end away from ground, it is bigger to Structural strength calls.

Utility model content

The utility model is in order to solve existing sand-proof sieve tube, and installation resistance is big, the irrational problem of bearing structure, there is provided A kind of taper sand-proof sieve tube, including wrapping wire, the rib that is arranged circumferentially along the wrapping wire, the wrapping wire wind the rib shape Integral taper.

Further, the scope of the taper of the overall taper is 15：1~10：1.

Further, the cross sectional shape of the rib is circle.

Further, the cross sectional shape of the wrapping wire includes first end and the second end, and the width dimensions at second end are big In the width dimensions of the first end, second end is located at outside, and the first end is located at inner side, the first end with it is described Rib contacts.

By the technical scheme of above-described embodiment, the sand-proof sieve tube installation resistance of taper is small, one end size away from ground Small, structural strength is big, and bearing structure is more reasonable.

Brief description of the drawings

Feature and advantage of the present utility model can be more clearly understood by reference to accompanying drawing, accompanying drawing be schematically without It is interpreted as carrying out any restrictions to the utility model, in the accompanying drawings：

Fig. 1 is the structural representation of the taper sand-proof sieve tube in the utility model some embodiments；

Fig. 2 is the front schematic view of the taper sand-proof sieve tube in the utility model some embodiments；

Fig. 3 is the wrapping wire schematic cross-section in the taper sand-proof sieve tube in the utility model some embodiments.

Embodiment

In order to be more clearly understood that above-mentioned purpose of the present utility model, feature and advantage, below in conjunction with the accompanying drawings and tool The utility model is further described in detail body embodiment.It should be noted that in the case where not conflicting, this Shen The feature in embodiment and embodiment please can be mutually combined.

Many details are elaborated in the following description in order to fully understand the utility model, still, this practicality New to be different from other modes described here using other to implement, therefore, the scope of protection of the utility model is simultaneously Do not limited by following public specific embodiment.

As shown in figure 1, the utility model provides a kind of taper sand-proof sieve tube 100, including wrapping wire 110, along the wrapping wire 110 ribs 120 being arranged circumferentially, the wrapping wire 110 wind the rib 120 and form overall taper.

The installation resistance of sand-proof sieve tube 100 of taper is small, and one end size away from ground is small, and structural strength is big, bearing structure It is more reasonable.

As shown in Fig. 2 the scope of the taper of the overall taper is 15：1~10：1.

The cross sectional shape of the rib 120 is circle.

As shown in figure 3, the cross sectional shape of the wrapping wire 110 includes the end 112 of first end 111 and second, second end 112 Width dimensions be more than the width dimensions of the first end 111, second end 112 is located at outside, and the first end 111 is located at Inner side, the first end 111 contact with the rib 120.Wrapping wire 110 is welded on by the rib by welded and installed mode On 120.

In the utility model, term " first ", " second ", " the 3rd " are only used for describing purpose, and it is not intended that referring to Show or imply relative importance.Term " multiple " refers to two or more, is limited unless otherwise clear and definite.

Preferred embodiment of the present utility model is the foregoing is only, is not limited to the utility model, for this For the technical staff in field, the utility model can have various modifications and variations.It is all in the spirit and principles of the utility model Within, any modification, equivalent substitution and improvements made etc., it should be included within the scope of protection of the utility model.
