Abstract
Provided is a paraffin scraping and straightening sucker rod. A sucker rod coupling is connected with a sucker rod body, four limiting sleeves are arranged on the sucker rod body at equal intervals in a hot casting mode, the limiting sleeves and the sucker rod body are fixed as a whole, and a first paraffin scraping and straightening body, a second paraffin scraping and straightening body, a third paraffin scraping and straightening body and a fourth paraffin scraping and straightening body are arranged outside the limiting sleeves in a hot casting mode from top to bottom; the first paraffin scraping and straightening body, the second paraffin scraping and straightening body, the third paraffin scraping and straightening body and the fourth paraffin scraping and straightening body are identical in structure and are provided with spiral scraping pieces and spiral paraffin discharging grooves, and the phase difference between adjacent paraffin scraping and straightening bodies after the paraffin scraping and straightening bodies are installed on the sucker rod body is 90 degrees, the limiting sleeves enable the position and the phase of each paraffin scraping and straightening body to be fixed, the distance between every two paraffin scraping and straightening bodies is smaller than the stroke length of a pumping unit, the inner wall of an oil tube can be scraped in the whole stroke in all directions, deposited paraffin on the inner wall of the oil tube can be completely removed, the effect of paraffin removal can be improved, and long-time normal production of an oil well is guaranteed.
Description
technical field:
The utility model relates to the process units that oil field wax deposition producing well is used, and is a kind of paraffin cutting centering sucker rod.
background technology:
In process of production, when oil stream flows from shaft bottom to well head, well temperature declines producing well gradually, and when lower than wax precipitation point, wax contained in crude oil will be separated out, and stops up oil flow channel, affects oil well production, need to carry out wax removal to oil well and just can make oil well normally produce.Existing dewaxing method is more, and one is that hot water circuit well-flushing makes wax dissolve outflow, but the low well of strata pressure is not suitable for hot water circuit well-flushing, because the low well of strata pressure can not form circulation, hot water can enter stratum and cause oil layer pollution; Another kind is in oil well, to add wax removal Ji, and this method cost is high, and overhead cost are high, less economical.Also having one is on sucker rod, to install additional to scrape wax stone, this scraping is connected on sucker rod, although paraffin scraper has all been installed between every sucker rod, because the length of every sucker rod is greater than the length of stroke of oil pumper, there are a lot of tube walls not scrape, the wax removal effect not reaching.
summary of the invention:
The purpose of this utility model is a kind of paraffin cutting centering sucker rod of design, can carry out whole process, comprehensive paraffin cutting to wax deposition section, improves wax removal effect, and guarantee oil well is normally produced.
The purpose of this utility model is achieved in that and comprises rod collar, sucker rod, the first paraffin cutting centralizer body, the second paraffin cutting centralizer body, stop collar, the 3rd paraffin cutting centralizer body, the 4th paraffin cutting centralizer body, beam hanger box cupling is connected with sucker rod, four equal stop collars of spacing of hot-cast on sucker rod, stop collar and sucker rod are fixed into one, at stop collar hot-cast the first paraffin cutting centralizer body from top to bottom outward, the second paraffin cutting centralizer body, the 3rd paraffin cutting centralizer body, the 4th paraffin cutting centralizer body, the first paraffin cutting centralizer body, the second paraffin cutting centralizer body, the 3rd paraffin cutting centralizer body, the structure of the 4th paraffin cutting centralizer body is identical, on it, there is spiral to scrape and chip and spiral de-waxing groove, the first paraffin cutting centralizer body, the second paraffin cutting centralizer body, the 3rd paraffin cutting centralizer body, the 4th paraffin cutting centralizer body is arranged on 90 ° of phase phasic differences between adjacent after sucker rod.
The beneficial effects of the utility model are: stop collar can make the position of each paraffin cutting centralizer body and phase place maintain static, on sucker rod, evenly install after four paraffin cutting centralizer bodies, distance between paraffin cutting centralizer body is less than the length of stroke of oil pumper, paraffin cutting centralizer body is arranged on 90 ° of phase phasic differences between adjacent after sucker rod, therefore, energy whole process and comprehensive scraping tube inner wall when the utility model moves up and down with oil pumper, can remove the wax deposition on tube inner wall completely, can improve wax removal effect, ensure long-term normal production of oil well, there is significant economic benefit.
brief description of the drawings:
Fig. 1 is the assembling drawing of the utility model embodiment.
detailed description of the invention:
Below in conjunction with Fig. 1, the utility model embodiment is described.
As seen from the figure, embodiment of the present utility model comprises rod collar 1, sucker rod 2, the first paraffin cutting centralizer body 3, the second paraffin cutting centralizer body 4, stop collar 5, the 3rd paraffin cutting centralizer body 6, the 4th paraffin cutting centralizer body 7, beam hanger box cupling 1 is connected with sucker rod 2, the equal stop collar 5 of four spacing of hot-cast on sucker rod 2, stop collar 5 is fixed into one with sucker rod 2, hot-cast the first paraffin cutting centralizer body 3 from top to bottom outside stop collar 5, the second paraffin cutting centralizer body 4, the 3rd paraffin cutting centralizer body 6, the 4th paraffin cutting centralizer body 7, the first paraffin cutting centralizer body 3, the second paraffin cutting centralizer body 4, the 3rd paraffin cutting centralizer body 6, the structure of the 4th paraffin cutting centralizer body 7 is identical, on it, there is spiral to scrape to chip 8 and spiral de-waxing groove 9, the first paraffin cutting centralizer body 3, the second paraffin cutting centralizer body 4, the 3rd paraffin cutting centralizer body 6, the 4th paraffin cutting centralizer body 7 is arranged on 90 ° of phase phasic differences between adjacent after sucker rod.The first paraffin cutting centralizer body 3, the second paraffin cutting centralizer body 4, the 3rd paraffin cutting centralizer body 6, the 4th paraffin cutting centralizer body 7 after being arranged on sucker rod 2 position and phase place each other maintain static.
