Abstract
The utility model relates to a nylon paraffin-scraping and centering device of a sucker rod. The problems of time consuming and labor consuming of the installation of a traditional centering device are mainly solved. The nylon paraffin-scraping and centering device of the sucker rod is characterized in that a main body (1) is made of a nylon material and is poured on the sucker rod, and 3 to 6 spiral convex edges (2) are evenly distributed outside the main body (1). The nylon paraffin-scraping and centering device of the sucker rod has the characteristics of scraping paraffin, centering and saving time and labor in installation.
Description
Technical field
The utility model relates to oil recovery field, oil field sucker rod used centralizer, especially nylon sucker rod paraffin cutting centralizer.
Background technology
Sucker rod is the important lifting parts of rod-pumped well.It is directly connected to the safety in production of rod-pumped well.In order to guarantee that sucker rod is centered in the oil pipe, the R a T that do not wear and tear need be installed some centralizers on sucker rod.And existing centralizer influences ordinary production because reasons in structure exists the problem that wastes time and energy of installing.
Summary of the invention
In order to solve existing centralizer the problem that wastes time and energy is installed.The utility model provides a kind of nylon sucker rod paraffin cutting centralizer.This nylon sucker rod paraffin cutting centralizer has paraffin cutting to be set upright, and time saving and energy saving characteristics are installed.Technical solutions of the utility model are: this nylon sucker rod paraffin cutting centralizer comprises main body, and main body is a nylon material, and casts on the sucker rod, and main body is evenly equipped with 3-6 spiral fin outward.
The utlity model has following beneficial effect: this nylon sucker rod paraffin cutting centralizer is owing to adopt the main body of nylon material, and casts on the sucker rod, and main body is evenly equipped with 3-6 spiral ridge outward.Owing to utilize the main body of nylon material, make R a T wear phenomenon can not occur.Owing to utilize casting process, this nylon sucker rod paraffin cutting centralizer directly is fixed on the sucker rod again, saves installation.Utilize the oil flow channel that faces mutually between fin at last, guarantee unblocked the flowing through of well liquid, simultaneously, in oil pumping process, can at any time the wax deposition on the tube inner wall be disposed, and flow out along the oil flow channel between fin, avoid wax deposition with well liquid.This nylon sucker rod paraffin cutting centralizer has paraffin cutting and sets upright thus, and time saving and energy saving characteristics are installed.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is Fig. 1 vertical views.
The 1-main body, the 2-fin.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further described: as Fig. 1 in conjunction with shown in Figure 2, this nylon sucker rod paraffin cutting centralizer comprises main body 1, and main body 1 is a nylon material, because of main body 1 adopts nylon material, make R a T wear phenomenon can not occur.And cast on the sucker rod, because of adopting casting process, this nylon sucker rod paraffin cutting centralizer directly is fixed on the sucker rod, save installation.Be evenly equipped with 4 spiral fins 2 outside the main body 1, make to guarantee unblocked the flowing through of well liquid by the oil flow channel that faces 2 of fins mutually, simultaneously, in oil pumping process, can at any time the wax deposition on the tube inner wall be disposed, and, avoid wax deposition with of the oil flow channel outflow of well liquid along 2 of fins.
