Description

A kind of machinery is turned round by force formula plunger rotor
Technical field
The utility model belongs to the anti-eccentric wear technical field of pumping well rod pump mechanical oil recovery roofbolt in petroleum industry, be specifically related to a kind of have prevent that the machinery of oil pump plunger piston or bottom rod string eccentric wear function from turning round by force formula plunger rotor.
Background technique
In pumping unit working procedure, whole rod string bearing tension effect all the time from bottom to top during upstroke, roofbolt end, oil pump plunger piston bearing tension is minimum, roofbolt top, wellhead polish rod suspension point bearing tension is maximum.During down stroke because roofbolt is subject to the frictional force contrary with moving direction, buoyancy, plunger frictional force, and the well liquid comprehensive functions such as local resistance that valve produces of flowing through, when bottom roofbolt gravity cannot be offset resistance upwards, on roofbolt, will produce neutral point, roofbolt is zero in this some place axial force, the above part roofbolt of neutral point bearing tension, the following part roofbolt of neutral point bears pressure, roofbolt end, be that oil pump plunger piston bears pressure maximum, roofbolt top, wellhead polish rod suspension point bearing tension is maximum.The existence of neutral point, especially in inclined shaft, deep-well, make the following part rod string of neutral point, be that unstability bending easily occurs neutral point position to the roofbolt within the scope of plungers length, it is disconnected de-that this part side attrition of rod string causing thus not only can cause sucker rod to occur at box cupling place, and can make the oil pipe of eccentric wear roofbolt corresponding position that wearing and tearing leakage occurs.
Moreover for short plunger oil-well pump, owing to connecting last root sucker rod of plunger, slide bar will enter in pump barrel with plunger in the course of the work, its external diameter is generally thinner, rigidity a little less than, and oil pumping rod centering device can not be installed.Harm computer collecting system being caused in order to alleviate bottom side attrition of rod string, in tratitional technology, adopt rod string base-weighted technology,, in above tens meters of neutral point or neutral point, adopt larger external diameter reality core pumping rod made by steel or greater density metal sucker rod to the rod string in scope between the slide bar of bottom, and a certain amount of oil pumping rod centering device is in position installed, this has played the effect that alleviates bottom side attrition of rod string harm to a certain extent.Yet, owing to being subject to the restriction of pump size overcurrent, pump type structure, slide bar relatively thin, the rigidity of the weighted lever external diameter on its top a little less than, and oil pumping rod centering device can not be installed, during again due to down stroke, slide bar and plunger are bearing maximum pressure, so slide bar will produce maximum bending deformation, easily cause thus slide bar wearing and tearing pump barrel inwall, thereby increase the gap leaking loss amount of plunger and pump barrel.The periodic pressure flexing of slide bar and pulling force extend that also can to cause that it is threaded with valve cover on plunger loosening, thereby increase the probability of this place's dropout.
In addition, after slide bar compressive deformation, due to the constrained of pump barrel and tube inner wall, will form with slide bar bottom to bottom plunger the bending moment that on plunger, valve cover threaded connection place is fulcrum.Because oil well is not desirable straight well, often all have certain gradient again, under oil well pump, deep-seated is put, and the hole deviation of place, pump depths well section will make oil well pump remain under heeling condition to work.Plunger tilting, the pressure-acting lower slide bar coupled columns bending moment that valve cover forms beyond the Great Wall, will make valve cover stressed deterioration when down stroke on plunger in addition, strengthen on plunger valve cover to the trend of curving distortion.Like this, the side that valve cover bends towards on plunger, by the frictional force increasing between plunger and pump barrel, thereby form the monolateral eccentric wear phenomenon of plunger, and because pump barrel forms constraint supporting leading role to plunger seal section, the monolateral eccentric wear phenomenon of plunger is mainly reflected on plunger and does not seal, external diameter is less than seal section, have on the relatively weak upper valve cover of circumferential liquid outlet, structural strength.The monolateral eccentric wear of plunger not only can scratch pump barrel inwall, reduces clearance seal performance, increase the wastage of oil well pump, and the crushed lemel wearing and tearing, in the silt particle of wrapped folder in well liquid, very easily causes holddown.On the other hand, oil well pump occupies the larger specific gravity of the total well of well maintenance operation time always from the well of valve cover fracture on plunger, and the disconnected well of statistics pump is found, have eighty per cant to ninety percent the disconnected well of pump time on plunger valve cover incision position and near have serious eccentric wear phenomenon.Analyze main cause, be on the one hand, on plunger, after valve cover place eccentric wear, bearing cross-section is long-pending to be reduced; Be on the other hand, during down stroke, on plunger, valve cover is subject to slide bar pressure to a side microbend, and be subject to during upstroke slide bar pulling force stretch or be microbend trend in the other direction to opposite direction, the tension and compression bending ringing so going round and beginning again, very easily cause the metal fatigue of valve cover on plunger, the scuffing groove that surperficial eccentric wear causes has formed tired source, and the expansion gradually of place, tired source microfissure finally causes oil well pump, from valve cover on plunger, fracture failure occurs.
Rod string base-weighted supporting centralizer righting technology can be alleviated neutral point to a certain extent to the eccentric wear of roofbolt between slide bar, but the eccentric wear of slide bar self, and but can not get effective solution by the plunger eccentric wear of slide bar pressure initiation.At present, there is a kind of rod rotor being arranged on wellhead polish rod, it utilizes one end to be connected on self rocking bar, one end is connected to the chain transferring power on pumping unit horsehead, tensioning chain move rocking bar while relying on horse head to move to lower dead centre, and then will comprise to polished rod by the rotor interior arrangement of rocking bar interlock, down to plunger, at interior whole sucker rod string rotating several angle, reach the effect of the whole anti-eccentric wear of rod string.But, because pumping well suspending point loading is generally larger, in actual production, the highest 120kN that surpasses, and, inclined shaft, high angle hole, or even horizontal well is more and more.And from the practical application effect of rod rotor, its to suspending point loading below 80kN, and it is more obvious that the maximum hole deviation of rod string well section of living in is no more than the oil well effect of 30 °, this kind of rod rotor cannot meet in the straight well of suspending point loading more than 80kN or the dark scope of pump hole deviation at the needs of the anti-eccentric wear of rod string of more than 30 ° inclined shafts.And oil field in tail period is along with deeply taking out the needs of taping the latent power, adopting by force extract, the shared ratio of inclined shaft, deep-well, the contour suspending point loading oil well of ultradeep well is increasing.This class oil well is because pump is deeply dark, hole deviation is larger, and on the unstability eccentric wear of the following roofbolt of neutral point and oil pump plunger piston, the fault urgent need such as the eccentric wear at valve cover place, fracture failure will solve.
