Abstract

An elastic deviation-adjustment wax scraper comprises an upper connection sleeve, a wax scraping sleeve, a limit sleeve, supporting spring pieces and a lower connection sleeve. The limit sleeve is hot-cast on a sucker rod, the upper connection sleeve and the lower connection sleeve are sleeved on the sucker rod, the upper connection sleeve is positioned above the limit sleeve, and the lower connection sleeve is positioned below the limit sleeve. The upper ends of the supporting spring pieces are fixed on the upper connection sleeve, the lower ends of the supporting spring pieces are fixed on the lower connection sleeve, a plurality of supporting spring pieces are evenly distributed, the wax scraping sleeve is sleeved outside the supporting spring pieces, and a spiral groove is sleeved on the wax scraping sleeve. The elastic deviation-adjustment wax scraper moves vertically in an oil tube along the sucker rod after being installed on the sucker rod to scrap wax on the inner wall of the oil tube. The radial position of the wax scraping sleeve can be adjusted through the elasticity of the supporting spring pieces, deviation of the sucker rod can be prevented, and abrasion is reduced. Therefore, the elastic deviation-adjustment wax scraper can fully clean the wax in the production process, and is low in wax cleaning cost and good in economic benefits.

Description

Elasticity tuningout paraffin scraper
Technical field:
The utility model relates to the process units that oil field wax deposition producing well is used, and is a kind of elasticity tuningout paraffin scraper.
Background technology:
Producing well in process of production, when well head flowed, the well temperature descended gradually from the shaft bottom for oil stream, when being lower than wax precipitation point, wax contained in the crude oil will be separated out, and stops up oil flow channel, influences oil well production, need carry out wax removal to oil well and just can make the oil well ordinary production.Existing dewaxing method is more, and a kind of is that the hot water circuit well-flushing flows out the wax dissolving, but the low well of strata pressure is not suitable for the hot water circuit well-flushing, because the low well of strata pressure can not form circulation, hot water can get into the stratum and cause oil layer pollution; Another kind is in oil well, to add the wax removal Ji, and this method cost is high, and overhead cost are high, and are less economical.
Summary of the invention:
The purpose of the utility model is a kind of elasticity tuningout paraffin scraper of design, makes things convenient for paraffin removal from oil well, reduces the paraffin removal from oil well expense.
The purpose of the utility model is achieved in that and comprises upper joint sleeve, paraffin cutting cover, stop collar, support spring sheet, lower joint sleeve; The stop collar hot-cast is on sucker rod, and upper joint sleeve, lower joint sleeve are sleeved on the sucker rod, and upper joint sleeve is in the top of stop collar; Lower joint sleeve is in the below of stop collar; Support spring sheet upper end is fixed on the upper joint sleeve, and support spring sheet lower end is fixed on the lower joint sleeve, and several support spring sheets evenly distribute; The outer suit paraffin cutting cover of support spring sheet, paraffin cutting has put spiral grooves.
The beneficial effect of the utility model is: the utility model is installed on the sucker rod back with sucker rod up-downgoing in oil pipe, the wax on the scraping tube inner wall, and the elasticity of support spring sheet can make paraffin cutting cover adjustment radial position; Can prevent the sucker rod skew; Reduce less wear, therefore, the utility model can be in process of production abundant wax removal; The wax removal expense is low, and is good in economic efficiency.
Description of drawings:
Fig. 1 is the assembling drawing of the utility model embodiment.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model embodiment is described.
Can be known that by figure the embodiment of the utility model comprises upper joint sleeve 1, paraffin cutting cover 2, stop collar 3, support spring sheet 4, lower joint sleeve 5, stop collar 3 hot-casts are on sucker rod 6; Upper joint sleeve 1, lower joint sleeve 5 are sleeved on the sucker rod 6, and upper joint sleeve 1 is in the top of stop collar 3, and lower joint sleeve 5 is in the below of stop collar 3; Support spring sheet 4 upper ends are fixed on the upper joint sleeve 1; Support spring sheet 4 lower ends are fixed on the lower joint sleeve 5, and several support spring sheets 4 evenly distribute, support spring sheet 4 outer suit paraffin cutting covers 2; On the paraffin cutting cover 2 spiral grooves is arranged, be convenient to the wax deposition that the well flow is moving and eliminating scrapes.
Stop collar 3 is fixed on sucker rod 6, limits the scope of activities of paraffin cutting cover 2 with this.
