Abstract
The utility model relates to the improvement of the structure of the sucker rod of the vertical paraffin depositing well and the inclined paraffin depositing well of an oilfield. The structure of the utility model fixes an uprighting wax scraping device on the sucker rod in a certain range to move. The uprighting wax scraping device is fixed in a certain range on the sucker rod to move by a baffle ring. After the fluctuated work of the sucker rod, the uprighting wax scraping device performs the functions of uprighting a tube wall by the sucker rod and scraping the wax. The baffle ring can bear static pressure of more than 4 tons. Compared with the original device, the utility model has more economic benefit and has simple and practical structure.
Description
The invention belongs to and strike off machinery.
Up to the present the special sucker rod that does not have this device both at home and abroad, there is producer with cementing agent baffle ring to be bonded on the sucker rod by hand at home, this baffle ring pulling force that is bonded on the sucker rod is short little application life, and the cost high-tensile strength is 1.8 tons (baffle ring requires pulling force more than 4 tons).
The present invention seeks to, solve the paraffin cutting problem of setting upright of deflecting well oil withdrawal bar, solved straight well wax removal problem, most importantly solve and on special sucker rod, fixedly set upright wax scraping apparatus.
This special sucker rod of the present invention is in the sucker rod external form, improves on the geometry and innovates, and promptly increases by seven baffle rings on bar.Alloy baffle ring of direct casting at a certain distance on bar is loaded onto a paraffin scraper in the middle of per 2 baffle rings, playing guiding and setting upright effect with wax removal.
The invention solves and on sucker rod, fixedly set upright wax scraping apparatus, solved the wax removal problem, in the producing well unit that does not have this special sucker rod, oil well continuous operation must the stopping production wax removal after one month once, with this special sucker rod can reach the wax removal that need not stop production within a year, the characteristics of this special sucker rod have certain resistance to corrosion, can use in the aqueous solution that normal atmosphere is depressed and on the oil product.Process means is simply compared with adhesive method and is improved about 10 times of work efficiency.
Fig. 1 is a kind of schematic diagram that has the special sucker rod of setting upright wax scraping apparatus of the present invention.
Below with reference to accompanying drawing one embodiment of the present of invention are made following detailed description.Baffle ring is that the cu-zn-al alloy material is cast on the sucker rod with casting method.This material melting temperature is 390 ℃ pours into a mould at 480 ℃～520 ℃, the cold back of water molding cleaning in the time of 270 ℃.Because this alloy fusion liquid good fluidity, stowage capacity is strong, and forming dimension is accurate, and clear-cut can use without machining.Especially the mechanical performance to sucker rod does not produce any influence.Static pressure reaches more than 4 tons can satisfy customer requirements fully, determines the position of baffle ring on bar according to the different strokes of oil pumper.
Claims (2)
1, a kind of special sucker rod of setting upright wax scraping apparatus that is equipped with is by sucker rod [1], baffle ring [2], centering paraffin scraper [3], form.It is characterized in that: on sucker rod [1], every 1～3 meter apart from direct casting on a garden shape baffle ring [2] so that centering paraffin scraper retaining is moved in 1～3 meter scope on this special sucker rod.
