Abstract

The invention discloses reduction spiral spring for tubing paraffin removal of a pumping well. The reduction spiral spring for the tubing paraffin removal of the pumping well comprises a body which is spiral springs made of elastic wire materials. The body which is arranged on a pumping rod which is arranged in the pumping well in a matching mode is corresponding to a tubing which is arranged inside the pumping well. The reduction spiral spring for the tubing paraffin removal of the pumping well is characterized in that a small diameter section spiral spring is connected with a large diameter section spiral spring to form into the body; the inner diameter of the small diameter section spiral spring is slightly smaller than the diameter of the pumping rod; and the outer diameter of the large diameter section spiral spring is slightly smaller than the inner diameter of the tubing. Compared with the prior art, the reduction spiral spring has the advantages of being high in rigidity, good in abrasion performance and long in service life due to the facts that the reduction spiral spring is made of elastic wire materials and the surface is covered with chromium coating; preventing blocking of the tubing due to the fact that paraffin coagulated on the tubing is scraped through the large diameter section spiral spring when the reduction spiral springs are performing up-and-down motion along the pumping rod; and being simple in structure and convenient to install and disassemble.

Description

A kind of Reducing screw spring for pumpingh well oil pipe wax removal
Technical field
The present invention relates to the oil exploration equipment annex, be specifically related to a kind of Reducing screw spring for pumpingh well oil pipe wax removal.
Background technology
Oil is in recovery process, and when oil stream was mobile to well head from the shaft bottom, the well temperature was fallen gradually, and when being lower than wax precipitation point, contained wax will be separated out and be attached on the oil pipe in the crude oil, causes oil pipe to stop up, and sucker rod is broken easily, influences the ordinary production of oil well.In order to prevent tubing wax, processing method commonly used at present has: chemical agent wax removal, hot-washing wax remover, mechanical paraffin removal etc.The chemical agent wax removal needs regularly to inject chemical agent in oil well, and not only cost height, and weak effect will cooperate heat to wash the ordinary production that just can keep oil well toward contact.Hot-washing wax remover consumes height, pollution is heavy, has not only reduced the permeability of oil reservoir, and has needed just can produce after heat is washed each time in 3-5 days.Mechanical paraffin removal is most common form, and with the circular paraffin cleaner that engineering plastics are made, the excircle of circular paraffin cleaner is provided with the oil groove of inclination, is respectively equipped with a circular paraffin cleaner at each stroke of sucker rod.Because circular paraffin cleaner quantity is many, oil flow channel is little, makes that the sucker rod resistance that moves up and down is big; Selected material hardness that the more important thing is circular paraffin cleaner is lower, wears no resistance, and application life is short.In order to reduce the cost of winning of oil, guarantee the ordinary production of oil well, need seek better wax removal apparatus.
Summary of the invention
The objective of the invention is the deficiency at the prior art existence, a kind of Reducing screw spring for pumpingh well oil pipe wax removal is provided, it is simple in structure, easy installation and removal not only, can also prevent that oil pipe from stopping up; The while long service life.
Technical scheme of the present invention is as follows:
A kind of Reducing screw spring for pumpingh well oil pipe wax removal comprises body, and described body is the helical spring that elastic wire is made, and is engaged on the sucker rod in the pumpingh well, and is corresponding with oil pipe in being located at pumpingh well, it is characterized in that:
Described body is linked to each other with the enlarged diameter section helical spring by the reduced diameter section helical spring and constitutes, and the helical spring internal diameter of described reduced diameter section is slightly less than the diameter of described sucker rod, and the helical spring external diameter of described enlarged diameter section is slightly less than the internal diameter of described oil pipe.
Further, the middle part of described body is described enlarged diameter section helical spring, and both ends are respectively described reduced diameter section helical spring.
Further, the middle part of described body is described reduced diameter section helical spring, and both ends are respectively described enlarged diameter section helical spring.
Further, described body is two sections described reduced diameter section helical springs and two sections alternate connecting and composing of described enlarged diameter section helical spring.
Further, described body is that circle, ellipse or polygonal elastic wire are made by the cross section.
Further, the surface coverage at described body has chromium coating.
The present invention compared with prior art has the following advantages:
(1) the Reducing screw spring is made by elastic wire, and surface coverage has chromium coating, and hardness is higher, and abrasion resistance is good, long service life;
(2) the Reducing screw spring move up and down with sucker rod process the time, the enlarged diameter section helical spring is wiped the wax that condenses on the oil pipe off, has prevented the oil pipe obstruction;
(3) simple in structure, the easy installation and removal of Reducing screw spring.
