Top connection is made as up-small and down-big shape; the microcephaly is provided with sucker rod box screw thread; major part is provided with the box screw thread that connects lower contact, is provided with liquid-through hole around the reducer ring, is provided with the limited step that holds annular magnet and anode protection ring in the endoporus at major part position.
Anodic protection is equipped with mesopore, is tubular.
Annular magnet is provided with mesopore, is tubular.
Establish mesopore in the paraffin cutting ring, be annular, outer wall is provided with vertical shape or the oblique broken wax pan of paraffin cutting.
Lower contact is made as up big and down small shape, the higher authorities are provided with the pin thread screw thread that is connected with the top connection coupling, following is provided with the box screw thread that is connected with connecting rod, is provided with liquid-through hole around the reducer ring, and the hypomere that faces the pin thread screw thread in the lower contact outside is provided with the undergauge step that holds the paraffin cutting ring.
Connecting rod up and down two ends is provided with identical sucker rod pin thread screw thread with top connection and lower contact coupling, the length of the length of connecting rod stroke of polished rod during less than oil pumping machine oil pumping.
The utility model has been compared following advantage with existing technology:
1, design is ingenious, rational in infrastructure, applicability is strong, can at any time the wax deposition of tube inner wall be wiped off in the oil well production process.
2, anode protection ring is established in inside, can reduce the extent of corrosion of oil pipe and sucker rod.
3, inside is provided with ring magnet, reduce the wax deposition degree by magnetization and polarization oil stream on the one hand, cause changes of magnetic field by toroidal magnet with moving up and down of sucker rod simultaneously, produce little eddy current at tube inner wall, produce a spot of heat, can lower viscosity of crude.
4, it is placed in the middle to set upright sucker rod, prevents sucker rod and oil pipe eccentric wear.
Four, description of drawings
Accompanying drawing is the structural representation that partly cuts open of the present utility model
1--top connection 2--anode protection ring 3--annular magnet 4--paraffin cutting ring 5--lower contact 6--connecting rod among the figure
Five, the specific embodiment
For further disclosing the technical solution of the utility model, elaborate by embodiment below in conjunction with Figure of description:
The utility model is made up of top connection 1, anode protection ring 2, toroidal magnet 3, paraffin cutting ring 4, lower contact 5 and connecting rod 6, it is characterized in that top connection 1 directly is threaded with lower contact 5; Anode protection ring 2 is arranged in the top connection inner chamber; Facing anode protection ring 2 lower ends in top connection 1 inner chamber is annular magnets 3, is compressed by lower contact 5 screw threads; Paraffin cutting ring 4 is located between top connection 1 and the lower contact 5, is enclosed within the undergauge place that lower contact 5 pin thread hypomeres are provided with, and fixing by top connection 1; Lower contact 5 lower ends are the connecting rods 6 that are threaded.
When using the utility model, earlier with pump and oil pipe G.I.H, lower piston then.Usually be in the characteristics near the surface well section according to oil well paraffinication, we dispose the connection length of the anti-eccentric wear corrosion-preventing device of wax removal below the wax deposition point degree of depth.Earlier anode protection ring 2 and annular magnet 3 are inserted in top connection 1 chamber; again paraffin cutting ring 4 is enclosed within the outside reducing place of lower contact 5; top connection 1 and lower contact 5 screwed connections are tightened; at last connecting rod 6 is connected on the box of lower contact 5 lower ends, the anti-eccentric wear corrosion-preventing device of some such wax removals is connected.Be lowered to piston, the deep well section lower sucker rod of wax deposition not, under the anti-eccentric wear corrosion-preventing device of then that several are such wax removal at the position of wax deposition.After piston is lowered to pump, connect polished rod, the dress well head connects oil pumper.
Start oil pumper and drive a well, oil pumper drives polished rod, wax removal anti-eccentric wear corrosion-preventing device, sucker rod and piston up-down, and the paraffin cutting ring 4 of the anti-eccentric wear corrosion-preventing device of wax removal with the wax deposition scraping of tube inner wall, is pumped to ground with oily stream in the process that moves up and down; Anode protection ring 2 has corrosion-resisting function; Toroidal magnet 3 is in the process that moves up and down, and the oily stream of ring is magnetized and polarizes and reduces the wax deposition degree in passing; Annular magnet causes the variation in magnetic field with moving up and down of sucker rod, produces little eddy current at tube inner wall, produces a spot of heat, can reduce viscosity of crude; It is placed in the middle that the anti-eccentric wear corrosion-preventing device of wax removal can be set upright sucker rod, has the effect that prevents sucker rod and oil pipe eccentric wear.
