Abstract
The utility model relates to a mechanical device used by a pumping well, and particularly to a novel oil pipe device capable of preventing eccentric wear of a sucker rod. The novel oil pipe device is provided with an oil pipe. The upper part of the oil pipe is provided with a three-way pipe. A flange is arranged on the oil pipe below the three-way pipe. A hollow pipe is suspended at the top end of the oil pipe through a ring. An oil pipe chamber is arranged between the hollow pipe and the oil pipe. A pressure cap is assembled on the top of the oil pipe through screw thread and presses the top part of the hollow pipe. The sucker rod penetrates the pressure cap and enters the hollow pipe. A packing II and a packing I are mounted on the lower part of the hollow pipe from bottom to top. A grease chamber is arranged between the packing II and the packing I. The lower end of the hollow pipe is provided with a packing pressure cap II through screw thread. A packing pressure cap I is compressed above the packing II through screw thread. The novel oil pipe device provided by the utility model has the functions of: effectively preventing eccentric wear of the sucker rod and oil pipe leakage by wear, saving force in operation process of the sucker rod, saving energy for 25% and improving yield for 10%.
Description
Technical field
The utility model relates to the mechanical device that rod-pumped well is used, and particularly relates to a kind of oil pipe device that can prevent sucker rod partial wear.
Background technology
At present, the main task of oil exploitation is to use oil pumper that underground crude oil is risen in surface duct.In oil recovery process, because the reasons such as hole deviation, roofbolt bending easily cause sucker rod and oil pipe to rub, not that sucker rod and box cupling mill is inclined to one side, be exactly oil pipe grinding is leaked, cause whole oil production equipment thrashing.Meanwhile, contain the impurity such as moisture content in oil, make the lubricity of sucker rod bad, particularly, when heavy crude producing, the up-downgoing of sucker rod is very difficult.
Summary of the invention
Technical problem to be solved in the utility model is, the deficiency existing for prior art and a kind of technical scheme that can prevent the oil pipe device of sucker rod partial wear is provided, the technical program can improve the lubricity of sucker rod, avoid the direct hard friction of sucker rod and oil pipe, can prevent eccentric wear, reach the object that improves oil recovery efficiency, reduces cost for oil production.
For achieving the above object, the utility model is by the following technical solutions: a kind of oil pipe device that can prevent sucker rod partial wear, it has oil pipe, tee piece is arranged at oil pipe top, flange is positioned on the oil pipe of tee piece below, it is characterized in that, hollow section is suspended on the top of oil pipe by annulus, between hollow section and oil pipe, there is oil pipe chamber, pressure cap is filled and is pressed in the top of hollow section at oil pipe top by Screw assembly, sucker rod enters hollow section through pressure cap, the bottom of hollow section is equipped with packing II and packing I from bottom to top, between packing II and packing I, there is butter chamber, packing pressure cap II is equipped with by screw thread in hollow section lower end, packing pressure cap I is pressed on packing II top by screw thread.
Between the top of described oil pipe and annulus, be provided with sealing ring.
The upper surface of described packing pressure cap I is provided with groove, and sucker rod is provided with the projection corresponding with groove.
The beneficial effects of the utility model are, the utility model is simple in structure, can effectively prevent sucker rod partial wear, also can prevent that oil pipe grinding from leaking, and sucker rod are laborsaving in running, energy-conservation 25%, improve productive rate 10%.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein, 1-pressure cap, 2-sealing ring, 201-annulus, 3-oil pipe, 4-tee piece, 5-hollow section, 6-oil pipe chamber, 7-flange, 8-external screw thread, 9-projection, 10-groove, 11-packing pressure cap I, 12-packing I, 13-butter chamber, 14-packing II, 15-packing pressure cap II, 16-sucker rod.
The specific embodiment
Below in conjunction with accompanying drawing, concrete structure of the present utility model and principle are described further.
As shown in the figure, a kind of oil pipe device that can prevent sucker rod partial wear of the present utility model, it has oil pipe 3, tee piece 4 is arranged at oil pipe 3 tops, flange 7 is positioned on the oil pipe 3 of tee piece 4 belows, it is characterized in that, hollow section 5 is suspended on the top of oil pipe 3 by annulus 201, between hollow section 5 and oil pipe 3, there is oil pipe chamber 6, pressure cap 1 is filled and is pressed in the top of hollow section 5 at oil pipe 3 tops by Screw assembly, sucker rod 16 enters hollow section 5 through pressure cap 1, the bottom of hollow section 5 is equipped with packing II 14 and packing I 12 from bottom to top, between packing II 14 and packing I 12, there is butter chamber 13, packing pressure cap II 15 is equipped with by screw thread in hollow section 5 lower ends, packing pressure cap I 11 is pressed on packing II 14 tops by screw thread, between the top of described oil pipe 3 and annulus 201, be provided with sealing ring 2, the upper surface of described packing pressure cap I 11 is provided with groove 10, and sucker rod 16 is provided with the projection corresponding with groove 10 9.
When using the utility model, to the interior injection lubrication oil of hollow section 5, the interior injection butter to butter chamber 13.When oil pumper moves, sucker rod 16 is in the interior operation of hollow section 5, and owing to being full of lubrication oil in hollow section 5, not only lubricity is good and be subject to certain buoyancy, prevents that sucker rod 16 and the inwall of oil pipe 3 from producing friction, prevented eccentric wear.Because there being the lubricated of lubrication oil and butter, the frictional force that sucker rod 16 is subject to is very little, has reduced idle work.Sucker rod is when operation, and oil elevates by oil pipe chamber 6, through tee piece 4, flows out.At oil pumper, move after a period of time, friction up and down due to sucker rod 16, make the gap between packing I 12 and packing II 14 and sucker rod 16 become large, at this moment, do not need sucker rod 16 and hollow section 5 proposition ground to tighten packing pressure cap I 11 and packing pressure cap II 15, and only the projection on sucker rod 16 9 need be put into the groove 10 in packing pressure cap I 11, rotate sucker rod 16 and tighten packing pressure cap I 11.Between the top of described oil pipe 3 and annulus 201, be provided with sealing ring 2, can better seal the gap between oil pipe 3 and hollow section 5 like this.
