Abstract
The utility model discloses an inner guide type anti wearing machine of sucker rod. The utility model comprises a column shaped anti wearing body 1 that is provided with a sucker rod 3. The utility model is characterized in that: the anti wearing body 1 is provided with a sucker rod 3 and guide holes 2 around the wearing body 1. The utility model has the advantages of rational structure, low manufacturing cost, and convenient use and can be widely adopted in various pumping well. Since the appearance of the machine is a column, the utility model has excellent upright effect of sucker rod and anti wearing effect and lone service life.
Description
Technical field: the utility model relates to a kind of oil field downhole tool, especially for the inner diversion type sucker rod abrasionproof device of oil well.
Technical background: before the utility model, abrasionproof device, centralizer structure that each oil field is used for well rod mostly are the cylinder that outer wall has guiding gutter vertically, its major defect is because the anti-abrasion body outer wall is damaged bigger, effectively the abrasionproof volume reduces, little with the tube inner wall contact area, set upright consequences such as effect and abrasionproof poor performance, application life is short thereby cause.
The purpose of this utility model is for oil well production provides a kind of inner diversion type sucker rod abrasionproof device because its outer wall shape complete circle cylinder comparatively is therefore big with the tube inner wall contact area, can have preferably set upright, abrasionproof performance and long application life.
Summary of the invention: the purpose of this utility model realizes that by following measure a kind of inner diversion type sucker rod abrasionproof device comprises the cylindrical anti-abrasion body that is processed with the beam hanger hole along the axle center, it is characterized in that also being processed with vertically around the beam hanger hole on the anti-abrasion body pod apertures.
The utility model reasonable in design, cost of production are low, easy to install, can be widely used in all kinds of pumpingh wells; Because its profile is complete or near complete cylinder, thereby have preferably that sucker rod is set upright, the abrasionproof effect, also can have long application life simultaneously.
Description of drawings: Fig. 1 is the structural representation of inner diversion type sucker rod abrasionproof device.
Inner diversion type sucker rod abrasionproof device is to be made of the cylindrical anti-abrasion body 1 that is processed with beam hanger hole 3 along the axle center, also is processed with a plurality of pod apertures 2 vertically around the beam hanger hole 3 on the anti-abrasion body 1 simultaneously.
The specific embodiment: inner diversion type sucker rod abrasionproof device using method and operating principle are, as required it is installed on the sucker rod by modes such as slot suit or direct thermoplastics, and beam hanger hole 3 covers at its center are stuck on the beam hanger body, the liquid stream behind the G.I.H in the oil pipe then can flow by pod apertures 2; Because anti-abrasion body 1 profile is complete cylinder, can bigger contact area be arranged with tube inner wall during work, therefore can have preferably set upright, the abrasionproof effect, also can have long application life simultaneously.
