Abstract
The utility model relates to the field of oil extraction equipment, and provides a novel sucker rod righting paraffin scraper which comprises a righting paraffin scraper body, a plurality of tower-shaped spiral teeth are arranged on the righting paraffin scraper body, and a spiral baffle is arranged at the top end of each tower-shaped spiral tooth and perpendicular to the tower-shaped spiral tooth. A longitudinal opening is arranged in the righting paraffin scraper body, and the size of the longitudinal opening is one third the diameter of the sucker rod. The novel sucker rod righting paraffin scraper can enlarge the open area of an oil pipe and reduce the resistance to motion of the righting paraffin scraper, not only has a relatively good righting effect, but also has excellent paraffin scraping performance, and is simple in structure, convenient to install, low in manufacturing coat and long in service life.
Description
Technical field:
The utility model relates to the accessory on a kind of oil production equipment, is specifically related to a kind of Novel sucker rod centering paraffin scraper.
Background technology:
With sucker rod pumping equipment crude oil extraction, two problems that wherein need to solve mainly are to prevent the bending of sucker rod and the wax deposition on removing oil pipe and the sucker rod, the bending of sucker rod can cause the pressure contact between sucker rod and oil pipe, and point out reciprocating friction in contact, cause the worn out accident of rod broken and oil pipe to occur, this situation is particularly serious in directional well and cluster well.Wax deposition on oil pipe or the sucker rod can cause the minimizing of flow section in the oil pipe, increases oil flow resistance.
Existing centering paraffin scraper mainly is divided into fixed and movable two kinds, fixed centering paraffin scraper is fixed on the sucker rod, move up and down with sucker rod, although this centering paraffin scraper has been taked some corresponding measures, resistance when moving to reduce it, but its shortcoming is the wax that can only remove on the oil pipe, can not dispose the wax on the sucker rod; Movable centering paraffin scraper, but the spiral number of teeth of this centering paraffin scraper is more, two ends are chamfering or fillet structure, thereby area of passage is little, the resistance of motion is large.
The utility model content:
The purpose of this utility model provides a kind of Novel sucker rod centering paraffin scraper, and it can overcome the drawback of prior art, increases the area of passage of oil pipe, reduces the resistance of motion of centering paraffin scraper, and existing preferably righting effect has again good paraffin cutting performance.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it comprises centering paraffin scraper body 1, be provided with several tower-like helical tooth 1-1 on the centering paraffin scraper body 1, the top of tower-like helical tooth 1-1 is provided with the helical baffle 1-2 vertical with tower-like helical tooth 1-1.
Be provided with a longitudinal opening 1-3 on the described centering paraffin scraper body 1.
The opening size of described longitudinal opening 1-3 is 1/3 of sucker rod 2 diameters.
The utility model centering paraffin scraper body 1 deliquescing after boiling heating, be stuck on the sucker rod 2 by longitudinal opening, hardening after 1 cooling of centering paraffin scraper body, the opening size of longitudinal opening 1-3 is designed to 1/3 of sucker rod 2 diameters, can guarantee that centering paraffin scraper body 1 at work can be from landing on the sucker rod 2, be provided with perpendicular helical baffle 1-2 in tower-like helical tooth 1-1 upper end, when guaranteeing oil pipe paraffin cutting effect, can also increase the area of passage of oil pipe, reduce at the volley suffered resistance of centering paraffin scraper body 1.
The utility model can be avoided the bending of sucker rod, prevent a series of major accidents such as rod broken that the friction because of sucker rod and oil pipe causes or oil pipe be worn out, increase the area of passage of oil pipe, reduce the resistance of motion of centering paraffin scraper, existing preferably righting effect has again good paraffin cutting performance, simple in structure, easy for installation, low cost of manufacture, high life.
Description of drawings:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is use view of the present utility model.
The specific embodiment:
Referring to Fig. 1, Fig. 2, this specific embodiment is by the following technical solutions: it comprises centering paraffin scraper body 1, be provided with several tower-like helical tooth 1-1 on the centering paraffin scraper body 1, the top of tower-like helical tooth 1-1 is provided with the helical baffle 1-2 vertical with tower-like helical tooth 1-1.
Be provided with a longitudinal opening 1-3 on the described centering paraffin scraper body 1.
The opening size of described longitudinal opening 1-3 is 1/3 of sucker rod 2 diameters.
This specific embodiment centering paraffin scraper body 1 deliquescing after boiling heating, be stuck on the sucker rod 2 by longitudinal opening, hardening after 1 cooling of centering paraffin scraper body, the opening size of longitudinal opening 1-3 is designed to 1/3 of sucker rod 2 diameters, can guarantee that centering paraffin scraper body 1 at work can be from landing on the sucker rod 2, be provided with perpendicular helical baffle 1-2 in tower-like helical tooth 1-1 upper end, when guaranteeing oil pipe paraffin cutting effect, can also increase the area of passage of oil pipe, reduce at the volley suffered resistance of centering paraffin scraper body 1.
This specific embodiment can be avoided the bending of sucker rod, prevent a series of major accidents such as rod broken that the friction because of sucker rod and oil pipe causes or oil pipe be worn out, increase the area of passage of oil pipe, reduce the resistance of motion of centering paraffin scraper, existing preferably righting effect has again good paraffin cutting performance, simple in structure, easy for installation, low cost of manufacture, high life.
