Abstract
A kind of beam hanger centralizer is characterized in that: centralizer main body 1 external surface is coated with anti-wear lubricating layer 2.The utility model is reasonable in design, simple in structure, easy to process, cost of production is low, result of use is good, the beam hanger that can be widely used in all kinds of pumpingh wells such as deep well pump, screw pump is set upright and abrasionproof, because anti-wear lubricating layer 2 has wear-resistant preferably and greasy property, not only can obviously prolong the workover cycle, can also alleviate wear problem simultaneously oil pipe or sleeve pipe.
Description
Technical field: the utility model relates to a kind of oil field downhole tool, especially for a kind of beam hanger centralizer of pumpingh well.
Technical background: before the utility model, each oil field is to prevent the wearing and tearing of pumpingh well beam hanger in production run, generally adopts the method that installs centralizer on the beam hanger body additional, prevents the eccentric wear of itself and oil pipe or sleeve pipe; This method is owing to be subjected to the restriction of centralizer abrasion resistance, and general application life is shorter, can not solve the wear problem to oil pipe or sleeve pipe simultaneously fully.
Summary of the invention: the purpose of this utility model is: for oil field pumping well production provides a kind of beam hanger centralizer, because its surface-coated has the anti-wear lubricating layer, can obviously improve application life, can also solve the wear problem to oil pipe or sleeve pipe simultaneously.
The purpose of this utility model realizes by following measure: a kind of beam hanger centralizer, comprise the centralizer main body, and it is characterized in that being coated with the anti-wear lubricating layer at centralizer main body external surface.
The purpose of this utility model can also realize by following measure: it is uniform that the anti-wear lubricating layer that centralizer main body external surface applies can be ring-type, and it is uniform also to can be strip.
The utility model is reasonable in design, simple in structure, easy to process, cost of production is low, result of use is good, the beam hanger that can be widely used in all kinds of pumpingh wells such as deep well pump, screw pump is set upright and abrasionproof, not only can obviously prolong the workover cycle, can also alleviate wear problem simultaneously oil pipe or sleeve pipe.
Description of drawings: Fig. 1 is the structural representation of beam hanger centralizer.
The beam hanger centralizer is to be made of the anti-wear lubricating layer 2 that centralizer main body 1 and external surface thereof apply.Anti-wear lubricating layer 2 can be according to different service condition requirements such as deep-well pump sump or screw bolt wells, and it is uniform or strip is uniform to be applied to ring-type.
The specific embodiment: the using method and the operating principle of beam hanger centralizer are: earlier it is installed on the beam hanger body, G.I.H just can prevent the direct friction of beam hanger and oil pipe or sleeve pipe during production run then; Simultaneously, because the anti-wear lubricating layer 2 that centralizer main body 1 external surface applies is made of composite materials such as multiple antiwear additive and sliding agents, have wear-resistant preferably and greasy property, prolong centralizer life cycle and the wearing and tearing that slow down oil pipe or sleeve pipe thereby reached.
