Abstract
The utility model provides an oil pipe hollow rod antiwear aid, which consists of an anti-corrosion antiwear plunger, an anti-corrosion high temperature resistant antiwear sliding sleeve, upper and lower joints and a sealing ring. The lower joint is threaded connected with the lower part of the anti-corrosion antiwear plunger. The anti-corrosion high temperature resistant antiwear sliding sleeve is sleeved with the anti-corrosion antiwear plunger. The upper part of the anti-corrosion antiwear plunger is threaded connected with the upper joint. The sealing ring is arranged inside a sealing slot of the upper joint. As the anti-corrosion high temperature resistant antiwear sliding sleeve is not moved in the oil pumping, the oil pipe has no wear caused by the friction on the roughened inner surface of the oil pipe, and also no wear is easily occurred even the relative sliding is existed between the smooth surface of the anti-corrosion antiwear plunger and the inner surface of the anti-corrosion high temperature resistant antiwear sliding sleeve. Therefore, the oil pipe hollow rod antiwear aid not only guarantees the none wear of the oil pipe and the hollow sucker rod but also guarantees the longer service.
Description
One, technical field
The utility model relates to the oil production equipment of petroleum industry, and particularly a kind of oil pipe, the wear-resistant pair of hollow stem belong to engineering goods.
Two, background technology
In sucker-rod pumping system, no matter be straight well or inclined shaft, hollow rod all is relative motion in contacting with oil pipe, therefore, exist inevitable wearing and tearing between hollow rod and the oil pipe, particularly deep-well and inclined shaft, hollow rod is easy to bending in oil pipe, serious oil pipe, hollow rod wear problem occur, after the generation wearing and tearing oil pipe and hollow rod can not be used, cause the oil well operation, oil well repair free period is short, increases operating cost, increases rod tube consumption, the oil well off-time is many, has reduced crude output.For avoiding oil pipe, hollow rod wear problems occurring, normal oil pipe, the hollow rod abrasionproof device of adopting on the oil recovery technique.Existing oil pipe, hollow rod abrasionproof device kind are more; generally all be to be fixed on the hollow rod; be synchronized with the movement with hollow rod; nonmetals and tube inner wall on the hollow rod abrasionproof device are done relative motion, because nonmetals are soft, oil pipe can not wear and tear; played temporary transient protective effect; but the non-metallic material grinding abrasion is very fast, and the time of protection oil pipe, hollow rod is short, and heavy wear still appears in oil pipe, hollow rod.
Three, summary of the invention
The purpose of this utility model is design a kind of oil pipe, the wear-resistant pair of hollow stem, makes himself long in life-span, and the oil pipe that do not wear and tear again avoids oil pipe, hollow rod oil pipe, hollow rod wear problems to occur in the bending of oil pipe internal cause, inclination.
The purpose of this utility model be achieved in that it by corrosion protection abrasion resistant plunger, anticorrosion refractory and antiwear sliding sleeve, go up lower contact and sealing ring is formed.During oil pumping, the corrosion protection abrasion resistant plunger is synchronized with the movement with hollow rod is upper and lower, because the frictional force of anticorrosion refractory and antiwear sliding sleeve external surface and pipe inner surface is greater than the frictional force of anticorrosion refractory and antiwear sliding sleeve inner surface and corrosion protection abrasion resistant plunger, so anticorrosion refractory and antiwear sliding sleeve does not move during oil pumping.
The beneficial effects of the utility model are: the wear-resistant pair of hollow stem is installed at the hole deviation position, wear-resistant sliding sleeve is fixed in the oil pipe, wear-resistant plunger slides up and down at wear-resistant sliding sleeve, hollow stem does not contact with oil pipe, thereby the friction and wear that makes hollow stem and oil pipe changes the friction and wear of the wear-resistant pair of hollow stem self into, reaches the purpose that prevents rod and tube partial-wear, reduces frictional resistance.Therefore, this oil pipe, the wear-resistant pair of hollow stem can guarantee that oil pipe, hollow rod do not wear and tear, and can also guarantee to have higher application life.
Four, description of drawings
Accompanying drawing is the assembling drawing of the utility model oil pipe, the wear-resistant pair of hollow stem.
Five, the specific embodiment
As shown in the figure, it is made up of lower contact 1, corrosion protection abrasion resistant plunger 2, anticorrosion refractory and antiwear sliding sleeve 3, top connection 4, sealing ring 5.Be connected with corrosion protection abrasion resistant plunger 2 lower thread by lower contact 1, anticorrosion refractory and antiwear sliding sleeve 3 is sleeved on the corrosion protection abrasion resistant plunger 2, and corrosion protection abrasion resistant plunger 2 tops are threaded with top connection 4, and sealing ring 5 is contained in the seal groove of top connection 4.Anticorrosion refractory and antiwear sliding sleeve 3 is made up of anticorrosion refractory and antiwear metal material brass, and the surface spraying weld nickel alloy of corrosion protection abrasion resistant plunger is handled.During oil pumping, corrosion protection abrasion resistant plunger 2 is synchronized with the movement with hollow rod is upper and lower, because the frictional force of anticorrosion refractory and antiwear sliding sleeve 3 external surfaces and pipe inner surface is greater than the frictional force of anticorrosion refractory and antiwear sliding sleeve 3 inner surfaces and corrosion protection abrasion resistant plunger 2, so anticorrosion refractory and antiwear sliding sleeve does not move during oil pumping.
Claims (2)
1, a kind of oil pipe, the wear-resistant pair of hollow stem are by it is characterized in that lower contact 1, corrosion protection abrasion resistant plunger 2, anticorrosion refractory and antiwear sliding sleeve 3, top connection 4, sealing ring 5 form.It is characterized in that: be connected with corrosion protection abrasion resistant plunger 2 lower thread by lower contact 1, anticorrosion refractory and antiwear sliding sleeve 3 is sleeved on the corrosion protection abrasion resistant plunger 2, and corrosion protection abrasion resistant plunger 2 tops are threaded with top connection 4, and sealing ring 5 is contained in the seal groove of top connection 4.
2, oil pipe according to claim 1, the wear-resistant pair of hollow stem is characterized in that: anticorrosion refractory and antiwear sliding sleeve 3 is made up of anticorrosion refractory and antiwear metal material brass, and the surface spraying weld nickel alloy of corrosion protection abrasion resistant plunger is handled.
