Abstract
The utility model relates to a strong magnetic rod oil well pump protector. As the conventional strong magnet is wax-control, but is mainly used for solving the problem of wax deposition on the oil pipe and is not provided with a dirt storage cavity, and most of the oil wells are directional wells, the pumping rod eccentric wear is unavoidable under the influence of the well mode during the oil extraction process. The strong magnetic rod oil well pump protector comprises an upper joint, a lower joint, an upper magnetic ring, a lower magnetic ring and an outer cylinder, wherein the upper and the lower joints are arranged at the upper and the lower ends of the outer cylinder respectively; and the upper and the lower magnetic rings are arranged on the upper side and the lower side on the inner wall of the inner cavity of the outer cylinder respectively. The strong magnetic rod oil well pump protector not only has the wax-control property of the prior art, but also can effectively suck the iron dust falling down from the inner cavity, so as to avoid pump sticking and wear aggravation; and at the same time, as the liquid flows through the inner cavity, the chain structure of the wax molecule is changed under the combined action of the upper and the lower magnetic rings, thereby avoiding the wax deposition. The strong magnetic rod oil well pump protector plays the double functions of wax control and sticking prevention.
Description
Technical field
The utility model relates to a kind of strong magnetic rod-type pumping unit protector.
Background technique
Present existing strong magnetic paraffin control, but it is primarily aimed at a little the just problem of tubing wax, is not provided with and deposits dirty chamber.Because most wells is directional well, in oil recovery process, is subjected to the influence of well bore form, sucker rod partial wear is the phenomenon that is difficult to avoid all the time.Although the beam hanger centralizer has been installed, eccentric wear has still produced a large amount of metal fillingss and a large amount of centralizer fragments, and these chips and broken piece are backward down directly to enter the oil well pump pump barrel, causes holddown or makes oil well pump wearing and tearing aggravation.
The model utility content
The technical problem that the utility model solved provide a kind of simple in structure, effectively prevent wax deposition, effectively adsorb the strong magnetic anti-sticking of the oil well pump wax control device that iron filings prevent the oil well pump fault.
A kind of strong magnetic rod-type pumping unit protector; its special way is: comprise upper connection, lower contact, upper magnetic ring, following magnet ring, urceolus; the two ends up and down of urceolus are provided with upper connection, lower contact respectively, and the upside of the interior cavity wall of urceolus and downside are provided with upper magnetic ring, following magnet ring respectively.
Above-mentioned upper connection and lower contact are connected with oil pipe respectively.
Gap between above-mentioned upper magnetic ring and the following magnet ring is for depositing dirty chamber.
Compared with prior art, the utility model not only possesses the wax control characteristic of original technology, and the iron filings that can effectively adsorb by the inner chamber whereabouts prevent holddown and wearing and tearing aggravation, simultaneously when flow of liquid during through inner chamber, magnet ring acts on simultaneously the waxy molecules chain structure is changed up and down, prevent the wax deposition, the utility model possesses the double action of wax control and anti-sticking simultaneously.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Referring to Fig. 1, the utility model comprises upper connection 1, lower contact 5, upper magnetic ring 2, following magnet ring 4, urceolus 3, and the two ends up and down of urceolus 3 are provided with upper connection 1, lower contact 5 respectively, and the upside of the interior cavity wall of urceolus 3 and downside are provided with upper magnetic ring 2, following magnet ring 4 respectively.
When iron filings fall by inner chamber, upper magnetic ring 2, down magnet ring 4 magnet absorption and it is sent into deposits in the dirty chamber.
When flow of liquid during through the utility model inner chamber, upper magnetic ring 2, magnet ring 4 acts on simultaneously the waxy molecules chain structure is changed down, prevents the wax deposition.
Upper connection 1 and lower contact 5 are connected with oil pipe respectively.
Claims (3)
