Abstract
The utility model discloses an anti-seize low-friction sealing pump efficiency booster. The booster main body comprises a liquid exhaust joint, an oil exhaust valve and a liquid inlet joint, wherein a sealed righting ring is arranged at the middle part of the booster main body; a plurality of lubrication blocks are uniformly inlaid on the righting ring; and a sealed ring or an opening ring structure is adopted. The anti-seize low-friction sealing pump efficiency booster has the integrated functions of seize prevention, low friction, high-efficiency sealing, oil rod righting and single direction diversion, can progressively decompose bearing pressure of a plunger of a deep well pump and reduce the possibility of sand jamming and abrasion of the plunger by achieving progressive connection between the plunger of the deep well pump of a pumping unit and the neutral point of an oil sucking rod through high-efficiency elastic sealing of the booster, and can relatively reduce elastic extension of the oil sucking rod, thereby sufficiently improving the pump efficiency and prolonging the maintenance-free period of the oil well.
Description
Technical field
The utility model relates to the improvement of oil-well pump of oil well pump efficiency exhausting-aid device structure, and the low frictional resistance sealing of a kind of anti-sticking pump efficiency booster especially is provided, and belongs to oil field oil recovery machiner equipment technical field.
Background technique
At present, the used oil-well pump of oil well pump efficiency exhausting-aid device in oil field is to adopt simple one-way valve structures, by the hierarchical composition between pumping unit deep-well pump osmanthus plug and rod string neutral point, share deep-well pump plunger pressure-bearing step by step, but in actual use, stuck phenomenon often takes place in booster in well, influenced normally carrying out of oil extraction operation.
Summary of the invention
The utility model discloses the low frictional resistance sealing of a kind of anti-sticking pump efficiency booster, has avoided problems such as big stuck, the wearing and tearing that occur easily of surface friction drag between the existing pump efficiency exhausting-aid device and the borehole wall.
Technical solution of the present utility model is as follows: the booster body comprises formations such as draining connector, oil extraction valve and liquid inlet joint, wherein, the middle part of booster body is provided with the sealing centering ring, evenly be inlaid with some lubricated pieces on the centering ring body, centering ring adopts closed circle or open circles ring structure.
Middle part at the booster body also is provided with transition joint, and it is two centering rings of two ends symmetrical distribution up and down, and the middle part is inlaid with O type seal ring.
Having down in the oil pipe of deep-well plunger pump, the utility model by with the rod string hierarchical composition, when upstroke, the oil extraction valve is closed, this moment 2 relative different openings orientation centering ring because tube inner wall is close in the tension force effect, form the single acting piston effect, with the lifting that makes progress of its upper liquid, because the classification pressure-bearing effect of multistage pump efficiency booster makes to act on the fluid column load minimizing of pump plunger top, pressure reduction.Effectively reduce plunger stroke loss and wearing and tearing leakage.When down stroke, the oil extraction valve is opened, and its underpart liquid imports top.When upper and lower stroke, as when running into mechanical admixtures such as sand, dirt and flowing through centering ring, centering ring bounces back automatically, can effectively avoid the pump efficiency booster stuck; As running into pump efficiency booster lateral deviation, centering ring still can be close to tube inner wall and compensate the eccentric gap leaking loss that forms of pump efficiency booster automatically.
Good effect of the present utility model is: the middle part of pump efficiency booster is provided with the sealing centering ring, the surface is inlaid with solid stick, reduced surface friction drag with oil pipe, open type centering ring structure has realized that tension force is self-sealed compensated, both having guaranteed has the space of enough circling round between rod tube, realized the effectively self-styled of pump efficiency booster again.Collect anti-jamming, low frictional resistance, efficient sealed, beam hanger is set upright, unidirectional water conservancy diversion is in one, by being connected with classification between the rod string neutral point at pumping unit deep-well tubing pump pump plunger, elasticity through booster is efficient sealed, decompose the cold pressure-bearing of deep-well pump plunger shaft step by step, reduction plunger sand card, wearing and tearing leakage youngster lead; And reduce the rod string elastic elongation relatively, and fully improve pump efficiency, prolong oil well repair free period.
