Abstract
The utility model relates to a whole-stroke self-adaption type paraffin-removing wire scraper for paraffin-troubled oil wells. The whole-stroke self-adaption type paraffin-removing wire scraper comprises a sucker rod. The whole-stroke self-adaption type paraffin-removing wire scraper is characterized in that a helical paraffin-removing wire scraper is mounted on the sucker rod, fixing clamps are respectively mounted on the sucker rod at both ends of the helical paraffin-removing wire scraper, and two sucker rod couplings are respectively mounted outside the fixing clamps. Aimed at the defects of conventional paraffin scrapers, the patent innovatively designs the whole-stroke self-adaption type paraffin-removing wire scraper with an elastic stainless steel flat wire as a basal body, the cross-sectional resistance is low, both sides are provided with sawtoothed edges, the whole-stroke self-adaption type paraffin-removing wire scraper is helically fixed on the sucker rod, and the diameter or pitch of the helical wire can be adjusted according to the upstroke and downstroke of the sucker rod and a tubing in order to ensure that a three-dimensional paraffin-scraping effect can be generated in the whole stroke in a wellbore; the elastic body can self-adaptively deform when the diameter of the tubing changes, thus ensuring that hard friction or jamming cannot take place as paraffin is removed, and the whole-stroke self-adaption type paraffin-removing wire scraper can be adapted to various well conditions, and can greatly reduce the frequency of periodical hot washing or chemical paraffin removal, thus reducing the production cost.
Description
Technical field
The utility model relates to a kind of for the omnidistance self-adapting type wax removal of waxing in production well line cutter, belongs to Petroleum Production technical field.
Background technology
The variations such as the wax component in crude oil can Yin Wendu in recovery process, pressure are separated out, and are attached on tubing wall or sucker rod, cause fluid passage to reduce, and sinker bar machine utilization, even causes oil well stopping production overhaul, affects output and benefit.Wax removal pipe nipple is installed conventionally on sucker rod or automatic crawling paraffin cleaner is installed on part straight well, but all there is blind spot in two kinds of modes.Rod stroke is 1 meter of left and right, and wax removal pipe nipple can only be removed the wax of regional area, and has mechanical blocking problem; Automatic crawling paraffin cleaner is only applicable to straight well, and two kinds of patterns have wax removal efficiency poor, and need regularly be washed by heat or paraffin removing with chemical method method is supplemented, and increase workload and cost of production.
Utility model content
This patent is for the deficiency of conventional paraffin scraper, innovative design omnidistance self-adapting type wax removal line cutter, take elastic stainless steel lenticular wire as matrix, section resistance is little, both sides have serrated edge, with spiral, be fixed on sucker rod, helix diameter or spacing be according to sucker rod up-down stroke and oil pipe adjustment, thereby guarantee omnidistancely in well letter to form three-dimensional paraffin cutting effect; When elastic body runs into oil pipe reducing can time self adaptation distortion, guarantee that wax removal does not occur again that hard grind is wiped or stifled card, can adapt to various hole conditions, by greatly reducing, regular heat is washed or the frequency of paraffin removing with chemical method, reduces production costs.
The purpose of this utility model is carried out specific implementation by the following technical programs:
A kind of for the omnidistance self-adapting type wax removal of waxing in production well line cutter, comprise sucker rod, spirality wax removal line cutter is installed on described sucker rod, on the sucker rod at described spirality wax removal line cutter two ends, is separately installed with fixation clamp, in the outside of each fixation clamp, be separately installed with rod collar.
The both sides of described spirality wax removal line cutter have serrated edge.
The advantage of this patent is: the one, line cutter is fixed on sucker rod with spiral form, and when sucker rod is twitched up and down, can form in omnidistance space cylindrical wax removal effect; The 2nd, line cutter cross section is little, and while moving up and down with sucker rod, resistance is little, does not affect sucker rod stressed; The 3rd, the sawtooth design of line cutter both sides, plays mechanical paraffin cutting effect at the Shi Junke that moves up and down; The 4th, line cutter two ends are fixed with clamp, and interlude is to flexibly connect, and when running into the variation of oil pipe caliber or actuating oil-pumping unit, can self adaptation be out of shape, and do not cause the machinery of sucker rod and oil pipe to damage and blocking; Above advantage has solved that conventional paraffin cleaner stroke is short, the halfway shortcoming of wax removal.
Accompanying drawing explanation
According to drawings and embodiments the utility model is described in further detail below.
Fig. 1 is a kind of structure chart for the omnidistance self-adapting type wax removal of waxing in production well line cutter described in the utility model embodiment.
Fig. 2 is the structure chart of the serrated edge of spirality wax removal line cutter.
In figure: 1, fixation clamp; 2, cylindrical wax removal space; 3, sucker rod; 4, oil pipe; 5, rod collar; 6, spirality wax removal line cutter; 7, serrated edge.
The specific embodiment
As shown in Figure 1-2, a kind of for the omnidistance self-adapting type wax removal of waxing in production well line cutter described in the utility model embodiment, comprise sucker rod 3, spirality wax removal line cutter 6 is installed on described sucker rod 3, on the sucker rod at described spirality wax removal line cutter 6 two ends, be separately installed with fixation clamp 1, in the outside of each fixation clamp 1, be separately installed with rod collar 5.
The both sides of described spirality wax removal line cutter have serrated edge 7.
The advantage of this patent is: the one, line cutter is fixed on sucker rod with spiral form, and when sucker rod is twitched up and down, can form in omnidistance space cylindrical wax removal effect; The 2nd, line cutter cross section is little, and while moving up and down with sucker rod, resistance is little, does not affect sucker rod stressed; The 3rd, the sawtooth design of line cutter both sides, plays mechanical paraffin cutting effect at the Shi Junke that moves up and down; The 4th, line cutter two ends are fixed with clamp, and interlude is to flexibly connect, and when running into the variation of oil pipe caliber or actuating oil-pumping unit, can self adaptation be out of shape, and do not cause the machinery of sucker rod and oil pipe to damage and blocking; Above advantage has solved that conventional paraffin cleaner stroke is short, the halfway shortcoming of wax removal.
