Abstract
The utility model relates to a pumping assistor of a beam-pumping unit, which is characterized by mainly consisting of an upper joint, a core tube, a spring, a sealing blow component, a sealing ring, a steel ball, a ball seat and a lower joint. A core tube body A and a core tube body B are fixedly connected with each other in a plugging manner to form the total core tube, the upper end of the core tube body A is in threaded connection with the upper joint, the core tube body A is provided with a sealing frame slidably matching with the core tube body A, a bowl-shaped sealing expansion ring is sleeved on the sealing frame, a sealing ring is arranged on the lower portion of the sealing expansion ring, four axial semi-circular elongated slots are uniformly distributed on an inner hole of the core tube body B and are in contact connection with the inner hole, a ball stopping rod is disposed on the upper portion of the inner hole of the core tube body B, the ball seat is placed on the lower portion of the inner hole of the core tube body B, the steel ball is placed on the ball seat, and the lower end of the core tube body is in threaded connection with the lower joint. The pumping assistor has the advantages that the pumping assistor is in segmented connection onto a sucker rod, is used for hoisting crude oil in oil tubes in a segmenting manner, and reduces upstream resistance of a plunger, thereby reducing internal leakage of a pump cylinder and increasing liquid yield of oil wells.
Description
Technical field
The utility model belongs to the oil pumper of producing well, relates in particular to a kind of discharge assisting and liquid increasing device of oil pumping machine.
Background technology
The oil pumper of producing well draws up in the next fluid and contains water, crude oil and fine sand.The up resistance of the plunger of oil pumper is very big, and leakage much has a strong impact on oilwell produced fluid amount in the pump barrel.Because roofbolt is eccentric in oil pipe, cause the situation of sealing cup inordinate wear, prolonged leather cup application life, increased maintenance cost.
The utility model content
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, and provide a kind of discharge assisting and liquid increasing device of oil pumping machine, it is the auxiliary pumping instrument of producing well oil pumper, its segmentation is connected on the rod string, be used for the crude oil in the segmentation lifting oil pipe, alleviate the up resistance of plunger, thereby reduce leakage in the pump barrel, improve oilwell produced fluid amount.
The utility model for achieving the above object, by the following technical solutions: a kind of discharge assisting and liquid increasing device of oil pumping machine, it is characterized in that: mainly by top connection, the core pipe, spring, the obturating cup assembly, joint ring, steel ball, ball seat and lower contact constitute, described core Guan Youxin tube body A and core tube body B two parts are pegged graft and are fixedly connected into core pipe integral body, described core tube body A upper end is threaded with top connection, core tube body A is provided with the sealing frame that is slidingly matched with it, be set with the bowl seal ring that rises on the described sealing frame, seal the ring bottom of rising and be provided with joint ring, uniform four axial semicircle elongated slots of described core tube body B endoporus and endoporus kiss connect, described core tube body B endoporus top is provided with the bar of blocking, core tube body B endoporus bottom is equipped with ball seat, be equipped with steel ball on the ball seat, described core tube body B lower end is threaded with lower contact.
Described sealing frame upper end is provided with the spring base that is threaded with it, is equipped with spring on the spring base.
Beneficial effect: its segmentation is connected on the rod string, is used for the crude oil in the segmentation lifting oil pipe, alleviates the up resistance of plunger, thereby reduces leakage in the pump barrel, improves oilwell produced fluid amount.Adopted the bowl seal ring that rises, the hermetically-sealed construction of the leather cup that promptly floats has prevented that effectively roofbolt is eccentric in oil pipe, causes the situation of sealing cup inordinate wear, has prolonged leather cup application life.Through field trial, the discharge assisting and liquid increasing device has played and has alleviated plunger load, increases the effect of oil well liquid outlet quantity.

The specific embodiment
Describe the specific embodiment of the present utility model in detail below in conjunction with accompanying drawing and preferred embodiment.As shown in the figure, a kind of discharge assisting and liquid increasing device of oil pumping machine, mainly by top connection 1, the core pipe, spring 3, the obturating cup assembly, joint ring 7, steel ball 9, ball seat 10 and lower contact 12 constitute, described core Guan Youxin tube body A2 and core tube body B11 two parts are pegged graft and are fixedly connected into core pipe integral body, described core tube body A upper end is threaded with top connection, core tube body A is provided with the sealing frame 6 that is slidingly matched with it, be set with on the described sealing frame bowl seal rise the ring 5, seal the ring bottom of rising and be provided with joint ring, uniform four the axial semicircle elongated slots 14 of described core tube body B endoporus connect with the endoporus kiss, described core tube body B endoporus top is provided with the bar 8 of blocking, core tube body B endoporus bottom is equipped with ball seat, be equipped with steel ball on the ball seat, described core tube body B lower end is threaded with lower contact.Described sealing frame upper end is provided with the spring base 4 that is threaded with it, is equipped with spring on the spring base.Rise ring and joint ring employing polyurethane material of sealing made.
Operating principle:
When rod string was descending, the liquid of discharge assisting and liquid increasing device bottom entered inner chamber by the inlet opening 13 of lower contact, backs down steel ball, arrived discharge assisting and liquid increasing device top via central tube, top connection outage.When rod string was up, steel ball cut out under the compressing of gravity and discharge assisting and liquid increasing device upper liquid.Black box also under the effect of spring and discharge assisting and liquid increasing device upper liquid, compresses sealing mat, and open bowl seal rise the ring leather cup be adjacent to tube inner wall, space, packing discharge assisting and liquid increasing device top and the bottom has stoped the descending of upper liquid.The discharge assisting and liquid increasing device plays the effect of piston and ball-and-seat in oil pipe, along with moving up and down of rod string, constantly take row on the lower liquid out of well head.Adopt the hermetically-sealed construction of unsteady leather cup, prevented that effectively roofbolt is eccentric in oil pipe, caused the situation of sealing cup inordinate wear, prolonged leather cup application life.Through field trial, the discharge assisting and liquid increasing device has played and has alleviated plunger load, increases the effect of oil well liquid outlet quantity.
The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment did.
