Description
Technical field
The present invention relates to field of petroleum machinery, and in particular to the paraffin removal equipment of well head nondestructive inspection.
Background technology
During oil exploitation, crude oil is extracted up by oil pipe, because silt in crude oil (especially viscous crude),
Paraffin and other impurity can be by oil pipe blockings, also burn into electric pump failure and other reasons, so every mouth oil well needs to carry out periodically
Maintenance.At this moment just need to extract in oil pipe to be repaired.The operation process is to utilize to hang liter system by the tubing string in oil well
It is proposed well head, unload and be placed on oil pipe storage rack by root, then again through over cleaning, measure, assemble again, then by it by root tripping in
In well.During oil producing operation, the expense that cleaning oil pipe is consumed is always important composition in oil extraction in oil field factory production cost
Part.The cleaning of oil pipe is a ring of most basic most critical in tubing repair technique.The cleaning quality of oil pipe is not only to follow-up
Process produces material impact, and is related to oil pipe use cost and the quality of construction operation.Transported from oil wells in field by oil pipe
It is defeated to pass through the multiple working procedures such as transport, storage, reparation to cleaning station, it is more in the prior art to be rinsed using high-temperature water, paraffin is removed,
But water waste can be caused by relying on high-temperature water to rinse, and it is flushed after spot taken away by current, environmental pollution can be caused.
The content of the invention
The technical problems to be solved by the invention be it is flushed after spot taken away by current, environmental pollution, mesh can be caused
The paraffin removal equipment for being to provide well head nondestructive inspection, the paraffin removal by the way of striking off, and by the spot struck off recycle.
The present invention is achieved through the following technical solutions：
The paraffin removal equipment of well head nondestructive inspection, including cylinder, cylinder are partly therefrom upper cylinder and lower cylinder, upper cylinder bag
Include the spot reclaiming chamber formed between inner and outer wall and inwall and outer wall；End face of the upper cylinder away from lower cylinder is provided with one
Individual discharging opening；Multiple de-waxing apparatus are provided with the inwall of upper cylinder；Lower cylinder includes lower cylinder inner wall, and lower cylinder inner wall is by upper
The inwall extension of cylinder is formed, and the lower cylinder inner wall is provided with probe close to one end of upper cylinder.
The present invention is cylinder, and sucker rod is pierced into the cavity in the middle part of cylinder, multiple remove is provided with the inwall of upper cylinder
Wax apparatus, de-waxing apparatus can strike off the paraffin on sucker rod surface, and the paraffin struck off is shedded into spot from sucker rod surface
In reclaiming chamber；Due to the cyclic structure of upper cylinder, the inwall for being provided with de-waxing apparatus can be by the annular surface of sucker rod
Paraffin is removed totally, also, because spot reclaiming chamber is also ring-type, the paraffin being removed can be reclaimed all；For the ease of
The processing of spot is reclaimed in paraffin scraper, discharging opening is set at the both ends of cylinder, such paraffin scraper can is reused.In lower circle
Probe is set on cylinder inwall, popped one's head in for the damage for detecting sucker rod.When upper cylinder and lower cylinder as overall in sucker rod table
When face is moved, upper cylinder needs to move on sucker rod surface to remove spot, during lower cylinder follows cylinder movement
Damage check progressively is carried out to sucker rod surface, can either so facilitate paraffin removal, the spot for avoiding removing pollutes environment, additionally it is possible to
Damage check is carried out to sucker rod, reduces the testing process of sucker rod.
Further, the discharging opening is annular shape, is arranged on the both sides of spot reclaiming chamber, and is provided with annular cover,
The size of annular cover and the size of discharging opening are adapted.Discharging opening is arranged to annular shape, is to increase the face of discharging opening
Product, the cleaning of the stain treatment and spot reclaiming chamber be easy in spot reclaiming chamber, using annular shape also for this hair of adaptation
Bright cylindrical structure.
Further, the de-waxing apparatus includes hole and strikes off blade, and multiple holes are evenly distributed on inwall；It is described
Strike off blade to be arranged on the downside of hole, strike off the knife face deviation inner wall of blade.Blade deviation inner wall is struck off, blade is just
Sucker rod surface can be touched and carry out paraffin removal work；The wax that blade strikes off drops into spot reclaiming chamber along knife face by hole
In；The downside of hole is in due to striking off blade, therefore, this determines the operative orientation of the present invention, will strike off the direction of blade
The direction of motion as the present invention.
Further, the blade for striking off blade is rolled into downwards tubular.In order to avoid blade damages sucker rod, by blade
Web-like is made, although reducing paraffin removal effect to a certain extent, it is contemplated that the cost of sucker rod is higher, it is therefore desirable to
Avoid striking off damage of the blade to sucker rod.
Further, the ring-type diameter that the blade for striking off blade in sustained height is formed on the inwall of cylinder is with taking out
Oil pipe external diameter is equal.It is by not exclusively cutting formation on inwall to strike off blade, therefore it is nothing to strike off between blade and inwall
Seam connection, striking off has certain elasticity between blade and inwall, therefore, even if sucker rod causes to take out due to surface covering paraffin
Beam hanger diameter increases, and sucker rod can be also put into progress paraffin in the present invention and struck off.
Further, the medium position of lower cylinder inner wall is provided with temperature sensor.Scraped by temperature sensor detection
The temperature change on the sucker rod surface after being streaked except blade, consequently facilitating the translational speed that control cylinder strikes off, avoids mobile speed
Spend and cause larger damage to sucker rod surface soon.
Further, one end away from upper cylinder is provided with multiple rollers on lower cylinder inner wall, and at least one roller connects
It is connected to displacement transducer.Roller is easy to fix the distance between cylinder and oil pick-up tube, while passes through the rotation of roller, displacement sensing
Device detects the translational speed of cylinder, position of the cylinder on sucker rod is obtained, when probe detects that sucker rod has in a certain position
During damage, the position can be marked for displacement transducer, be easy to the fast positioning to sucker rod damage location.
The present invention compared with prior art, has the following advantages and advantages：
1st, the present invention solves sucker rod in the prior art using de-waxing apparatus and the cylinder of spot reclaiming chamber is accompanied with
The environmental pollution of cleaning, while avoid the waste at water source；
2nd, the present invention can either facilitate paraffin removal, and the spot for avoiding removing pollutes environment, additionally it is possible to which sucker rod is damaged
Detection, reduce the testing process of sucker rod；
3rd, the present invention sets displacement transducer, when probe detects that sucker rod has damage in a certain position, displacement sensing
The position can be marked for device, be easy to the fast positioning to sucker rod damage location.
