Abstract
The utility model discloses a reusable follow-up wax removal device for oil pumping well tube poles, belonging to wax removal equipment. The reusable follow-up wax removal device is composed of a wax removal shuttle, an upper reversing tube, a lower reversing tube and limiting stops, wherein the wax removal shuttle in a tube column and an axis sleeve are laminated on an oil pumping pole; spring sheets at two ends of the wax removal shuttle tightly hold the oil pumping pole; and the tube column is internally provided with the upper reversing tube, the lower reversing tube, an upper limit stop and a lower limit stop. Compared with the prior art, the reusable follow-up wax removal device for the oil pumping well tube poles, disclosed by the utility model, can prevent inclined abrasion of the oil pumping pole to play a centering function, and has the advantages of convenience in installation, high work reliability, low safety hazard and long service life.
Description
Technical field
The utility model belongs to paraffin removal unit, relates to a kind of reusable oil pumping well casing roofbolt servo-actuated paraffin removal unit specifically.
Background technology
Oil oil pick-up tube paraffin removal unit is a kind of power that rod string pumps in the oil recovery process that utilizes and rely on, and the servo-actuated intermittent movement realizes the uninterrupted function of removing oil pipe, the inside and outside wall wax deposition of bar.The automatic paraffin cutting erection device of existing beam hanger pumpingh well wax deposition section; Its weak point is that complex structure, component are more, difficult installation, critical piece easy deformation are damaged, fault rate is high; Can only disposablely use, and use big limitation is arranged, only can be applied in the straight well.
Summary of the invention
In order to address the above problem, the utility model aim to provide have the rod string centralizing function, prevent eccentric wear, wax removal is clean thoroughly, the characteristics of environmental protection, do not have a kind of reusable oil pumping well casing roofbolt servo-actuated paraffin removal unit of potential safety hazard.
A kind of reusable oil pumping well casing roofbolt servo-actuated paraffin removal unit technology contents of the utility model: be to constitute by wax removal shuttle, last reversing tube, following reversing tube and positive stop; Technological improvement as the utility model; Wax removal shuttle concentric is nested on the sucker rod and the spring leaf at wax removal shuttle two ends is held sucker rod tightly in the tubing string, is provided with reversing tube, reversing tube and positive stop up and down down in its tubing string.
As the further improvement of the utility model, be provided with in the ring week of the shuttle body of wax removal shuttle and vertically pass through groove, ratchet stretches out shuttle from pass through groove external, is provided with the paraffin cutting blade on week at the ring that passes through the groove two ends, the ring of symmetry is provided with the spring leaf that constitutes vertebra shape on week at the two ends of shuttle body.
As the further improvement of the utility model, spring leaf is an arc spring leaf.
As the further improvement of the utility model, the radial dimension that is provided with at least three ratchets that pass through groove and wherein stretch out the ring week of shuttle body is greater than the internal diameter of the tubing string internal diameter less than last reversing tube.
As the further improvement of the utility model, constitute by positive stop ring week internal diameter less than the external diameter of the spring leaf of vertebra shape.
A kind of reusable oil pumping well casing roofbolt servo-actuated paraffin removal unit of the utility model compared with prior art can prevent sucker rod partial wear, plays centralizing function, have easy for installation, functional reliability is high, potential safety hazard is low, the beneficial effect of long service life; Need not other energy consumption, wax removal is clean thoroughly, environmental protection, wide adaptability; Be applicable to oil well such as inclined shaft, directional well, horizontal well and thin oil, viscous crude, the high wet goods crude oil that coagulates; But the characteristics with repeated application can effectively prolong the oil well pump detection period, reduce cost for oil production.
Description of drawings
Fig. 1 is a kind of reusable oil pumping well casing roofbolt servo-actuated paraffin removal unit overall structure sketch map.
The specific embodiment
A kind of reusable oil pumping well casing roofbolt servo-actuated paraffin removal unit of the utility model; Be to constitute by wax removal shuttle 1, last reversing tube 2, following reversing tube 3 and positive stop 4; Wax removal shuttle 1 concentric is nested on the sucker rod 6 and the spring leaf at wax removal shuttle 1 two ends 7 is held sucker rod tightly in the tubing string 5, is provided with reversing tube 2, reversing tube 3 and positive stop 4 up and down down in its tubing string 5.Constitute by positive stop 4 ring week internal diameter less than the external diameter of the spring leaf 7 of vertebra shape.
Be provided with in the ring week of the shuttle body 8 of wax removal shuttle 1 and vertically pass through groove 9, ratchet 10 from stretching out outside the shuttle body 8 groove thoroughly, be provided with paraffin cutting blade 11 on week at the ring that passes through groove 9 two ends, the ring of symmetry is provided with the spring leaf 7 that constitutes vertebra shape on week at the two ends of shuttle body 8.Spring leaf 7 is an arc spring leaf.
The radial dimension that is provided with at least three ratchets 10 that pass through groove 9 and wherein stretch out the ring week of shuttle body 8 is greater than the internal diameter of tubing string 5 internal diameter less than last reversing tube 2.
