Abstract
The utility model discloses an oil well pumping unit used in the oil field, in particular to an anti-wear pumping aid synergistic wax scraping centralizer, and comprises an oil pumping short section, a centralizing piece, a sealing cover and a sealing seat. The inner sides of the centralizing piece and the sealing cover are provided with metallic frameworks, and the inside of the protruding arris of the centralizing piece is provided with an oil through hole. The intensity of the centralizing piece and the sealing cover are increased, the centralizer can not be abraded and damaged easily, and the capacity of the oil to pass through the centralizer and the oil pumping effect are improved.
Description
Technical field
The utility model relates to a kind of oil rig of machine producing well, refers in particular to the abrasionproof of installing in a kind of pipe nipple of sucker rod and the rod connector thereof and helps and take out the synergy centralizer.
Background technology
At present, oil field, the whole nation has all entered the oil recovery stage in later stage, the oil recovery liquid measure is successively decreased year by year, and the eccentric wear well in most of oil fields is all in rising trend, and particularly Daqing oil field eccentric wear well is more, and enters polymer three from water flood recovery and adopt period, in complete 30,000 mouthfuls of producing wells of grand celebration, the eccentric wear well is competed up to nearly 50%, solves rod and tube partial-wear and helps the technical problem of taking out synergy, referred agenda.Chinese patent 02283772.8 discloses a kind of piston type Oil-increasing pup joint, and its pipe nipple can be set upright sucker rod and oil pick-up tube, also can play the effect that increases the oil pumping amount.But the whole difficulty of processing of this centralizer is very big, the method of by specification can not realize the technical method that valve seat is cast on the valve body, implement difficultly in other words, and finished product has caused certain waste in case can only the integral replacing pipe nipple after damaging.
Summary of the invention:
The purpose of this utility model is to provide that a kind of pumping efficiency is higher, the processing replacement cost is low, and a kind of abrasionproof of more can be effectively sucker rod and oil pick-up tube being set upright helps takes out synergy paraffin cutting centralizer.
The utility model is to realize like this, it sets upright part in the middle part of comprising sucker rod substitute, bottom at sucker rod substitute is equipped with seal receptacle, and seal receptacle and sucker rod substitute be by being threaded, and is provided with a sealing shroud that is active on the sucker rod substitute between part and the seal receptacle setting upright.Inner and set upright the metallic framework that part inside is equipped with the multiple tracks bending at sealing shroud.Have along the through hole of fin trend in the fin inside of setting upright part.
Advantage of the present utility model is, owing to be provided with the sealing shroud of setting upright between part and the seal receptacle, makes to enter the crude oil of setting upright in the part and better sealed, and when sucker rod moves upward crude oil fully promoted; The through hole that centralizer fin inside is offered has increased the throughput of crude oil; More than the implementation of two kinds of structures, increased pumping efficiency.Seal receptacle and sucker rod substitute adopt thread connecting mode, make and are setting upright part or sealing shroud, and seal receptacle can be convenient for changing when damaging, and needn't destroy whole pipe nipple, have also reduced difficulty of processing simultaneously.
In setting upright part, sealing shroud, added the metallic framework of multiple tracks bending, increased their intensity, made it in high temperature crude oil, also be unlikely to distortion.
Description of drawings:
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is an another kind of structural representation of the present utility model.
Fig. 3 is that the utility model figure sets upright part upper end A-A sectional view.
1-sucker rod substitute wherein, the 2-sealing shroud, 3-sets upright part, the 4-seal receptacle.
The specific embodiment:
The utility model will be further described below in conjunction with accompanying drawing:
As shown in Figure 1 the utility model be by a sucker rod substitute and be positioned at sucker rod substitute middle part and on sucker rod substitute the movable part 3 of setting upright, be positioned at the sealing shroud of setting upright below the part 32, and the seal receptacle 4 that is positioned at below the sucker rod substitute is formed.Be provided with metallic framework in the inside of the lower end of setting upright part 3, also be provided with multiple tracks bending metallic framework in sealing shroud 2 inside through the multiple tracks bending; Seal receptacle 4 is by being threaded with sucker rod substitute.By Fig. 1, Fig. 2, Fig. 3 as can be seen, in the fin of setting upright part 3, also have the hole of passing through for crude oil.
Sucker rod substitute 1 among Fig. 1 is that an internal thread by two sections different-diameters is formed, and its small-diameter thread end cooperates with the upper end of sucker rod substitute, and its large-diameter thread is identical with the connecting thread of sucker rod.
The difference of Fig. 2 and Fig. 1 is inverted in the connected mode of its sucker rod substitute and box cupling seal receptacle is installed.
Claims (4)
