Abstract
This utility model relates to a sucker rod roller thread off prevention rotating paraffin cutting centralizer used in the oil field and oil well operation, which comprises an extension rod with a nylon paraffin cutting sleeve sleeved outside the wall. Oil pump connector cylindrical roller brackets are respectively connected with the two ends of the extension rod; a plurality of roller grooves penetrating the bracket body are distributed on the roller bracket along the axial direction; and a roller, the axes of which is perpendicular to the axes of the bracket is installed in each roller groove through a positioning pin. Because a roller mechanism is arranged at the lower part of the centralizer, the eccentric wear of the pipe can be effectively prevented during the operation, and the centralizer has the advantages that the design structure is simple and reasonable, the operation and the installation are convenient and reliable, the cost is low, and the work efficiency is high, and the product is very suitable for being widely used in the oil field operation.
Description
Technical field
The utility model belongs to petroleum drilling and mining device technique field, relates to a kind of sucker rod roller anticreep rotation paraffin cutting centralizer that uses in the oilfield job execution.
Background technology
In the oilfield job execution,, the paraffin cutting centralizer to be set on oil pipe usually, go into the well smoothly to guarantee oil pipe for preventing that gathering such as wax and grease foreign material is bad to the resistance wearing and tearing that the oil well pump oil pipe causes in oil well hole anomaly and the oil well casing.But existing all kinds paraffin cutting centralizer also exists in actual applications, and the inclined to one side frictional resistance of wheel rim is big, abrasive action strong, defectives such as inconvenient, unreliable are installed, the rod tube that causes pumping is worn in a short time, disconnected taking off, reduce application life, have influence on production process and operating efficiency to a great extent.
The utility model content
The purpose of this utility model is to overcome the above-mentioned defective that prior art exists, so a kind of project organization advantages of simple is provided, operation is easy installation and reliable, cost is low, frictional resistance is little, the sucker rod roller anticreep of long service life and high efficiency rotates the paraffin cutting centralizer.
Be used to realize that the technical solution of foregoing invention purpose is such: the sucker rod roller anticreep rotation paraffin cutting centralizer that is provided has the extension bar that a wall is set with a nylon paraffin cutting cover outward, termination overcoat load at extension bar is connected to the oil pump joint, another termination overcoat load at extension bar is connected to a tubular rolling wheel support, in rolling wheel support upper edge axial distribution 2～4 roller grooves that run through support body are arranged, by alignment pin a wheel axis and the axial vertical roller of support are housed all in each roller groove, the span of angle is 0 °～180 ° between the wheel axis of adjacent two rollers.During work, the oil pump joint of centralizer is connected with the oil pipe oil well pump, this device is gone into the well with oil pipe and since device nylon paraffin cutting supporting positive cover be contained in oil well pump below, therefore can scrape off oil well pump, and set upright oil pipe with wax deposition in the setting of casing; Again because this centralizer has idler wheel mechanism, friction between itself and the oily wall casing is the rolling friction of friction factor minimum, so it has the little characteristics of oily wall casing wearing and tearing, can effectively prevent rod and tube partial-wear, reduce the oil recovery energy consumption, and then prolong the application life of equipment and oil well greatly.In addition, the utility model also have be easy to install, advantages such as cost is low, good reliability, its product is highly suitable for the oil field operation scene and promotes the use of.
