Abstract
The utility model relates to a special type rotatable blowing wax scraping device. The wax scrapping device comprises a rope socket joint and a rapid joint; the upper end of the rope socket joint is connected with a rope socket; the lower end of the rapid joint is connected with a weighted lever; a connecting supporting rod is connected between the rope socket joint and the rapid socket; wax scrapping sheets are hinged to the support rod; and a positioning hoop for axially stopping the wax scrapping sheets is fixed on the support rod. According to the utility model, wax scrapping area can be increased; wax scrapping quality can be improved; wax clearing period of an electric pump well is effectively extended; load of the electric pump well is reduced; and pump inspection period of the electric pump well is extended.
Description
Technical field
A kind of extraordinary rotation blowing paraffin scraper used when the utility model relates to the construction of electric pump well paraffin cutting in oilfield downhole operation.
Background technology
At present, there is following shortcoming in the old-fashioned electric pump well paraffin scraper of applying on oil field: the one, and paraffin scraper is designed to entirely seal state, easily occurs that wax stone blocks duct situation in paraffin cutting process; The 2nd, in paraffin cutting process, paraffin scraper does not rotate, part well wax removal weak effect; Long-term this paraffin scraper that uses causes electric pump well tube inner wall knot hard wax bed thickness, is difficult to remove.The 3rd, old type paraffin scraper does not have screwed connection head, and steel wire is directly connected with paraffin scraper connecting ring, needs a bite well to knit rope socket one time, and the time-consuming material that takes, causes electric pump well period of removing the wax shorter, and individual well wax removal number of times increases, and increases workload.
Utility model content
In order to improve electric pump well paraffin cutting quality, effectively extend the period of removing the wax of electric pump well, the utility model provides a kind of extraordinary rotation blowing paraffin scraper.This paraffin scraper can increase paraffin cutting area, improves paraffin cutting quality, effectively extends the period of removing the wax of electric pump well, alleviates electric pump well load, extends electric pump well pump detection period.
The technical solution of the utility model is: a kind of extraordinary rotation blowing paraffin scraper, comprise the snap joint that rope socket joint that upper end is connected with rope socket and lower end are connected with weighted lever, between rope socket joint and snap joint, be connected support bar, wherein, the hinged paraffin scraper of above-mentioned support bar, is also fixed with for the spacer ferrule to paraffin scraper axial limiting on support bar.
Above-mentioned paraffin scraper is flight-shaped, is fixedly set in two turning hinges on support bar on flight, and the spacer ferrule on above-mentioned support bar is on paraffin scraper between two turning hinges.
The beneficial effects of the utility model are: in such scheme, it is rotary that prime minister is improved to half sheet by the full closeding state of old-fashioned paraffin scraper, under using this paraffin scraper, rushes to while carrying, and it can strike off the wax on oil pipe tube wall get off easily, pipe aperture is increased, and oil circulation is smooth; The 2nd, make paraffin scraper into rotatable pattern, in paraffin cutting process, runner is wide, non-resistance, upper and lower speed is fast, improves wax removal quality; The 3rd, increased screwed connection head, avoided repeating to beat material unaccounted-for (MUF) and the expenditure of time that rope socket causes.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
1-rope socket joint in figure, 2-support bar, 3-turning hinge, 4-spacer ferrule, 5-paraffin scraper, 6-plug, 7-snap joint.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, this special type rotation blowing paraffin scraper, upper end is the rope socket joint 1 being connected with rope socket, lower end is the snap joint 7 being connected with weighted lever, rope socket joint 1 is connected support bar 2 with 7 of snap joints, wherein, the hinged paraffin scraper 5 of above-mentioned support bar 2, is also fixed with on support bar 2 for the spacer ferrule 4 to paraffin scraper 5 axial limitings.In above-mentioned snap joint with ball hole radially, and communicate with axial hole, first snap joint 7 one end are connected with weighted lever, the plug 6 of support bar lower end inserts the radially ball hole of snap joint 7 other ends again, and then plug 6 axial rotation are just connected with snap joint 7.
Above-mentioned paraffin scraper 5 is flight-shaped, is fixedly set in two turning hinges 3 on support bar 2 on flight, and the spacer ferrule on above-mentioned support bar 4 between two turning hinges 3, moves up and down formula position for limiting paraffin scraper 5 on paraffin scraper.
In such scheme, owing to paraffin scraper being made into half envelope, by bottom pressure blowing wax removal, can increase paraffin cutting area, improve paraffin cutting quality, effectively extend the period of removing the wax of electric pump well, alleviate electric pump well load, extend electric pump well pump detection period; Meanwhile, increase screwed connection head, avoided repeating to beat material unaccounted-for (MUF) and the expenditure of time that rope socket causes.
