Abstract
The utility model discloses a kind of Novel contracting formula paraffin scraper, the connecting rod to be linked together including scraper and by fixture, retainer ring is set respectively on the top and the bottom body of rod of connecting rod, it is respectively perpendicular on the outer wall of retainer ring and compression spring is set, described scraper top and the bottom is connected with described compression spring respectively.The utility model makes oil well normally produce, adds oil-well time-rate, reduce production cost per tone oil, alleviate the labor intensity of employee, obtained the accreditation of employee and technical staff in use, paraffin scraper can shrink unfreezing automatically.
Description
Technical field
It the utility model is related to a kind of Novel contracting formula paraffin scraper.
Background technology
At present in flowing well production process, because crude oil is in flow rate process, temperature reduces, and separates out wax and is bonded at tubing wall
Above, it is necessary to which paraffin scraper wax removal, often generation paraffin scraper is stuck during wax removal, causes steel wire tap, it is impossible to normal wax removal,
The well production is caused to decline, the time one is grown, and oil pipe blocks, it is necessary to well workover.Kill-job operation is needed before well workover, is had in washing well process
A part of flushing fluid pours into bottom, pollutes, and also needs to propose spray after well workover.If proposing spray failure, the well can be caused to turn to take out
It can resume production.The production run expense of the well is increased, reduces well yield.
The content of the invention
The purpose of this utility model is to provide a kind of Novel contracting formula paraffin scraper, and paraffin scraper can shrink unfreezing automatically, make
Oil well normally produces, and adds oil-well time-rate, reduces production cost per tone oil, alleviates the labor intensity of employee, obtained employee and
The accreditation of technical staff.
The purpose of this utility model is achieved in that a kind of Novel contracting formula paraffin scraper, including scraper and by solid
Determine the connecting rod that part links together, retainer ring is set respectively on the top and the bottom body of rod of connecting rod, divided on the outer wall of retainer ring
Compression spring is not vertically arranged, and described scraper top and the bottom are connected with described compression spring respectively.
The utility model adds small-sized damper respectively in the connecting rod top and the bottom of paraffin scraper, includes single spring.When
It when paraffin scraper blocks, can inward shrink, paraffin scraper external diameter is diminished, under upper lifting power, be automatically performed unfreezing.Normal clear
During wax, the size constancy of paraffin scraper.The utility model is simple and reasonable, and paraffin scraper can shrink unfreezing automatically, makes oil well normal
Production, adds oil-well time-rate, reduces production cost per tone oil, alleviate the labor intensity of employee, obtained employee and technical staff
Accreditation.
Brief description of the drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is main structure diagram of the present utility model.
Embodiment
A kind of Novel contracting formula paraffin scraper, as shown in figure 1, including scraper 5 and the company to be linked together by fixture 4
Extension bar 1, the end of connecting rod 1 set suspension ring respectively.Retainer ring 2 is set respectively on the top and the bottom body of rod of connecting rod 1, it is fixed
It is respectively perpendicular on the outer wall of ring 2 and compression spring 3 is set, the suit of compression spring 3 is arranged in a tubular holder, and tubulose is solid
Reservation is arranged on the outer wall of retainer ring 2.The described top and the bottom of scraper 5 are connected with described compression spring 3 respectively.In work, when
When scraper 5 is hampered, it will be compressed to movement at connecting rod 1, compression spring 3, the radial position size of scraper 5 reduces, and is able to certainly
Dynamic unfreezing.By the way that when being hampered section, in the presence of recompressing spring 3, scraper 5 continues to recover its original operating position.
