Traditional injection well downhole flow regulator seating nipple scale removal, uses a kind of gauguste cutter, and during scale removal, gauguste cutter is connect with weighted lever After be put into oil pipe, oil pipe is then sling, then gone into the well by well testing truck by crane.Such scale removal, time-consuming and laborious, operation processing cost It is high.

Invention content

In view of this, the utility model provides a kind of scale removal utensil, which is connected to throw in catcher bottom, with pulling Device in tripping in injection well downhole flow regulator seating nipple, in the case where not needing to increase workload, realizes the barrel incrustation that works injection well downhole flow regulator together Scraping removal.

For achieving the above object, the technical solution adopted in the utility model is：

A kind of scale removal plug, including：

Ontology；

The ontology, upper part have helicitic texture, and lower part is frustum cone structure；

The helicitic texture is connect with throw in catcher bottom thread；

The outer surface of the frustum cone structure has fin；

The fin is used for scraping injection well downhole flow regulator seating nipple inner wall.

Preferably, the fin is oblique fin.

Preferably, the oblique fin is several, and groove is formed between adjacent two oblique fin；

The groove for storing the incrustation scale scraped temporarily, prevents incrustation scale from entering between seating nipple inner wall and throw in catcher Annular space is so as to stuck throw in catcher.

Preferably, the lower section of the frustum cone structure, which has, is oriented to wimble structure；

The guide cone, for ensureing centralizer body and seating nipple of the ontology by injection well downhole flow regulator.

Preferably, annular groove is set between the helicitic texture and frustum cone structure of the ontology；

Sealing ring built in the annular groove；

The sealing ring, for preventing screw thread from moving back button.

The beneficial effects of the utility model：The scale removal plug of the application, is connected to throw in catcher bottom, is removed with throw in catcher one Well according to the operating method of throw in catcher, in the case where not needing to increase workload, is realized to incrustation in injection well downhole flow regulator seating nipple Scraping, scaling operation are simple, quick, at low cost.

Description of the drawings

By below with reference to description of the attached drawing to the utility model embodiment, the above-mentioned and other mesh of the utility model , feature and advantage it is apparent, in the accompanying drawings：

Fig. 1 is a kind of structure diagram of scale removal plug of the utility model embodiment.

Specific embodiment

The utility model is described below based on embodiment, but what deserves to be explained is, the utility model is simultaneously unlimited In these embodiments.It is detailed to describe some specific detail sections below in the datail description of the utility model.So And for the part of no detailed description, those skilled in the art can also understand the utility model completely.

In addition, it should be understood by one skilled in the art that the attached drawing that is provided is simply to illustrate that the utility model Objects, features and advantages, attached drawing are not to be actually drawn to scale.

Meanwhile unless the context clearly requires otherwise, otherwise throughout the specification and claims " comprising ", "comprising" etc. Similar word should be construed to the meaning included rather than exclusive or exhaustive meaning；That is, it is " including but not limited to " Meaning.

Fig. 1 is a kind of structure diagram of scale removal plug of the utility model embodiment.As shown in Figure 1：

A kind of scale removal plug, including：

Ontology；

Body upper part has helicitic texture 6, and lower part is frustum cone structure 2；

Helicitic texture 6 is connect with throw in catcher bottom thread；

The outer surface of frustum cone structure 2 has fin 3；

Fin 3 is used for scraping injection well downhole flow regulator seating nipple inner wall.

Further, in Fig. 1, fin 6 is oblique fin.

Further, in Fig. 1, oblique fin is several, and groove 4 is formed between adjacent two oblique fin；

Groove 4 is used to store the incrustation scale scraped, the annular for preventing incrustation scale from entering between seating nipple inner wall and throw in catcher temporarily Space is so as to stuck throw in catcher.

Further, in Fig. 1, the lower section of frustum cone structure 2, which has, is oriented to wimble structure 1；

Guide cone 1, for ensureing centralizer body and seating nipple of the ontology by injection well downhole flow regulator.

Further, in Fig. 1, annular groove 5 is set between the helicitic texture 6 of ontology and frustum cone structure 2；

Sealing ring built in annular groove 5；

Sealing ring is buckled for preventing screw thread from moving back.

Specifically, simple illustration is carried out to the use of the utility model with reference to Fig. 1：

Scale removal plug is connect with throw in catcher bottom thread, is gone into the well with throw in catcher, is not had with throw in catcher normal operating method It has any different.When throw in catcher passes through injection well downhole flow regulator, guide cone 1 ensures centralizer body and seating nipple of the scale removal plug by injection well downhole flow regulator, removes Dirty plug fin contacts at first with the seating nipple inner wall of injection well downhole flow regulator.Oblique fin 3 is scale removal plug and injection well downhole flow regulator in order to prevent Scraping ability declines when the contact of seating nipple inner wall is uneven, and groove stores the incrustation scale scraped temporarily, prevents it from entering in seating nipple Annular space between wall and throw in catcher is so as to stuck throw in catcher.

Embodiment described above only expresses the embodiment of the utility model, and description is more specific and detailed, but simultaneously Cannot the limitation to the utility model patent range therefore be interpreted as.It should be pointed out that the ordinary skill people to this field For member, without departing from the concept of the premise utility, several deformations, equal replacement can also be made, improved etc., these Belong to the scope of protection of the utility model.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
