The structural relation of the flowing well bipolar paraffin scraper is that the top end and the bottom end of a central rod are provided with a hanging ring respectively, wherein the hanging ring at the top end is connected with a paraffin removal steel wire, and the hanging ring at the bottom end is connected with a plumb; the upper part and the lower part of the central rod are provided with four righting rods; a large-diameter paraffin scraper and a paraffin scraper are fixedly arranged on the central rod by the righting rods; the righting rods are connected with the large-diameter paraffin scraper and the paraffin scraper by welding and are connected with the central rod through a hollow ring, so that the paraffin scraper can freely rotate during descending; the upper part and the lower part of the central rod are provided with a paraffin scrapping needle assembly respectively; the paraffin scraper and the large-diameter paraffin scraper are positioned by the paraffin scrapping needle assemblies; the lower part of the central rod is provided with a righting guide device; the righting guide device is formed by uniformly welding three triangular iron sheets outside a cylinder; the iron sheets are chamfered; and a sharp cutting edge is arranged at one end of each of the iron sheets.
Description
Technical field: a kind of paraffin cutting technology, especially bipolar paraffin scraper of flowing well and the method for using that the present invention relates to oil recovery field, oil field.
Technical background: during the flowing well ordinary production, owing to contain wax and colloid in the crude oil, when oil temperature is lower than wax deposition point; Wax in the crude oil will be separated out; In the tube inner wall deposition, knot amasss into wax and colloidal bitumen, increases oil flow resistance; Even can block oil flow channel, directly influence the ordinary production of oil well.It is long that wax removal technology originally exists the wax removal time, and working strength is big, the problem of wax removal difficult quality guarantee.
Summary of the invention: the purpose of this invention is to provide simple in structure; Bipolar paraffin scraper of easy to operate flowing well and method for using, it solved exist in the present technology technical problem, the objective of the invention is to realize like this; It is link, righting rod, paraffin cutting pin assembly, big footpath paraffin scraper, center-pole, paraffin scraper, set upright guiding device and be formed by connecting; Center-pole top and bottom are respectively equipped with a link, and the top link is connected with the wax removal steel wire, and the bottom link is connected with vertical.
The upper and lower position of center-pole is provided with four righting rods; Righting rod is fixed on big footpath paraffin scraper and paraffin scraper on the center-pole; Righting rod is with footpath paraffin scraper, paraffin scraper are for being welded to connect greatly, and righting rod is that cavity ring is connected with center-pole, rotates freely in the time of can making big footpath paraffin scraper and paraffin scraper descending.
The diameter of paraffin scraper is less than the diameter of big footpath paraffin scraper, and the up face of paraffin scraper is designed to outer chamfering, and descending face is designed to interior chamfering; Big footpath paraffin scraper is 8 fonts.
The upper and lower position of center-pole is respectively equipped with a paraffin cutting pin assembly, and paraffin cutting pin assembly positions paraffin scraper and big footpath paraffin scraper.
The center-pole bottom is provided with sets upright guiding device, and setting upright guiding device is outside a cylinder, evenly to weld three leg-of-mutton iron plates, and this iron plate is the chamfering shape, and an end has keen edge.
Method for using of the present invention is: at first by the first wax removal of the wax scraping slice of minor diameter, big footpath paraffin scraper carries out thorough wax removal again; Can reduce the resistance of paraffin cutting like this, improve the speed of paraffin cutting, once can accomplish wax removal and handle, prevent the generation of bit freezing; Paraffin cutting pin assembly breaks into pieces to the wax that paraffin scraper scrapes with the up big wax stone sheet of oil gas, discharges pit shaft with oil gas again, to guarantee that oil pipe is unimpeded.
Meaning of the present invention is: can reduce the resistance of paraffin cutting, improve the speed of paraffin cutting, once can accomplish wax removal and handle, prevent the generation of bit freezing; Set upright guiding device and be outside a cylinder evenly three leg-of-mutton iron plates of welding, this iron plate has chamfering, and an end has keen edge, can further play paraffin cutting and centralizing function; Paraffin cutting pin assembly can break into pieces to the wax that paraffin scraper scrapes with the up big wax stone sheet of oil gas, discharges pit shaft with oil gas again, to guarantee that oil pipe is unimpeded, prevents that the crown drill accident from taking place.
Description of drawings: Fig. 1 is the structural representation of the bipolar paraffin scraper of flowing well, among the figure 1, link 2, righting rod 3, paraffin cutting pin assembly 4, big footpath paraffin scraper 5, center-pole 6, paraffin scraper 7, set upright guiding device
The specific embodiment: embodiment 1, the present invention be link 1, righting rod 2, paraffin cutting pin assembly 3, big footpath paraffin scraper 4, center-pole 5, paraffin scraper 6, set upright guiding device 7 and be formed by connecting; Center-pole 5 tops and bottom are respectively equipped with a link 1; Top link 1 is connected with the wax removal steel wire, and the bottom link is connected with vertical.
Embodiment 2, center-pole 5 upper and lower positions are provided with four righting rods 2; Righting rod 2 is fixed on big footpath paraffin scraper 4 on the center-pole 5 with paraffin scraper 6; Righting rod 2 and big footpath paraffin scraper 4, paraffin scraper 6 are for being welded to connect; Righting rod 2 and center-pole 5 rotate freely in the time of can making big footpath paraffin scraper (4) and paraffin scraper (6) descending for cavity ring is connected.
The diameter of embodiment 3, paraffin scraper 6 is less than the diameter of big footpath paraffin scraper 4, and paraffin scraper 6 up faces are designed to outer chamfering, and descending face is designed to interior chamfering; Big footpath paraffin scraper 4 is 8 fonts.
Embodiment 4, center-pole 5 upper and lower positions are respectively equipped with a paraffin cutting pin assembly 3, and 3 pairs of paraffin scrapers of paraffin cutting pin assembly 6 position with big footpath paraffin scraper 4.
Embodiment 6, method for using of the present invention are: at first by the wax scraping slice 6 first wax removals of minor diameter, big footpath paraffin scraper 4 carries out thorough wax removal again; Can reduce the resistance of paraffin cutting like this, improve the speed of paraffin cutting, once can accomplish wax removal and handle, prevent the generation of bit freezing; The wax that 3 pairs of paraffin scrapers of paraffin cutting pin assembly scrape with the up big wax stone sheet of oil gas breaks into pieces, and discharges pit shaft with oil gas again, to guarantee that oil pipe is unimpeded.
