Abstract
The utility model provides an oil pipe post is taken out to self -lubricating sucker rod abrasionproof, oil pipe is intraductal in the cover down, oil pipe's upper portion exit end side -mounting oil pipe valve, sheathed tube upper portion exit end mounting sleeve valve, oil pipe's the sealed ware of upper portion exit end installation well head, go into in the oil pipe under the sucker rod, the sealed ware of well head is passed to the upper end of sucker rod, the oil reservoir communicates with each other with the sleeve pipe, oil pipe's lower part connects gradually the screen pipe, the packer, the oil -well pump, the outside suit urceolus of screen pipe, there is the annular channel between screen pipe and the urceolus, there is the UNICOM hole on the upper portion of screen pipe, the UNICOM hole with an oil pipe section of thick bamboo with annular channel UNICOM, the liquid in the annular space that packer and bobbin seal messenger sleeve pipe and oil pipe formed can not flow the lower part of packer, the crude oil of isolating gather in an oil pipe section of thick bamboo, makes sucker rod and oil pipe inner wall soak in crude oil, produces lubrication action to it, prevents that sucker rod, oil pipe from wearing and tearing, prolongs the production cycle of pumpingh well greatly, the reduction investment cost has apparent economic benefits.
Description
Technical field
The utility model is the oil rig of oil field machinery oil, is a kind of oil rig preventing sucker rod and oil pipe from wearing and tearing, specifically a kind of self-lubricating sucker rod anti-abrasion pumping pipe string.
Background technology
In sucker-rod pumping, no matter be straight well or inclined shaft, sucker rod and oil pipe are all relative motions in contacting, inevitably there is sucker rod, oil pipe wear problem, along with the continuous exploitation in oil field, well water rises, lubricating condition declines, corrosivity increases, and sucker rod, oil pipe wearing and tearing etching problem is on the rise, and has become the principal element shortening the oil well production cycle.Prevent sucker rod, oil pipe from wearing and tearing at present and have following several method: 1 is install oil pumping rod centering device on sucker rod, but short from the application life of oil pumping rod centering device viewed from a large amount of actual conditions, and sucker rod, oil pipe wear problem can not effectively solve; 2 is install oil pipe rotating device at well head, and make the whole circumference of tube inner wall all participate in wearing and tearing by rotation pipeline, extend oil pipe and be worn down to the non-serviceable time, this method still exists wear problem, so solution that neither be desirable; 3 is adopt without oil pipe oil pumping, although this oil pumping mode does not exist the problem of wearing and tearing oil pipe, there is the problem of wearing and tearing sucker rod and sleeve pipe; 4 is adopt liner oil pipe, and this method Meteorological is high, and pipe aperture is reduced, under enter pump footpath and be restricted, affect oil well output, can only eccentric wear be slowed down, still there is certain eccentric wear problem.Although the measure of several solution sucker rod, oil pipe wear problem achieves certain effect above, Meteorological is high, greatly increases cost of production.
Summary of the invention
The purpose of this utility model is to provide a kind of self-lubricating sucker rod anti-abrasion pumping pipe string, overcomes above-mentioned Problems existing, prevents the wearing and tearing between sucker rod and oil pipe, improve its application life, director's oil well production cycle, reduce fund input, reduce cost of production, improve oil well economic benefit.
The technical scheme that the utility model adopts is: comprise wellhead sealing device, tubing valve, sleeve valve, sucker rod, sleeve pipe, oil pipe, screen casing, urceolus, packer, oil well pump, under oil pipe in sleeve pipe, the upper outlet end side surface of oil pipe installs tubing valve, the upper outlet end mounting sleeve valve of sleeve pipe, the upper outlet end mounting shaft sealer for mouth of oil pipe, enter under sucker rod in oil pipe, the upper end of sucker rod is through wellhead sealing device, oil reservoir communicates with sleeve pipe, the bottom of oil pipe connects screen casing successively, packer, oil well pump, the outside suit urceolus of screen casing, annular channel is had between screen casing and urceolus, linked hole is arranged at the top of screen casing, described linked hole is by oil pipe cylinder and described annular channel UNICOM, liquid in the annular space that packer and bobbin seal make sleeve pipe and oil pipe be formed can not flow to the bottom of packer, the bottom of sucker rod connects the piston of oil well pump.
The beneficial effects of the utility model are: under the effect of packer, the oil-water mixture that oil well pump is extracted out flow to annular channel from the linked hole screen casing, upwards flow from annular space after turning to the bottom flowing to urceolus downwards again and be plucked out of, mixed liquor is when flowing to annular channel and turning to downwards, fluid is separated under the effect of density contrast, isolated crude oil is upwards gathered in oil pipe cylinder, R a T inwall is made to be immersed in crude oil, lubrication is produced to it, substantially there is not sucker rod, the problem of oil pipe wearing and tearing, therefore the utility model can reach purpose of design, overcome problems of the prior art, greatly can extend the production cycle of pumpingh well, and investment cost is low, easy to implement, practicality is good, there is significant economic benefit.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing 1, embodiment of the present utility model is described.
As shown in Figure 1, embodiment of the present utility model comprises wellhead sealing device 1, tubing valve 2, sleeve valve 3, sucker rod 4, sleeve pipe 5, oil pipe 6, screen casing 11, urceolus 12, packer 13, oil well pump 14, oil pipe 6 times is in sleeve pipe 5, the upper outlet end side surface of oil pipe 6 installs tubing valve 2, the upper outlet end mounting sleeve valve 3 of sleeve pipe 5, the upper outlet end mounting shaft sealer for mouth 1 of oil pipe 6, sucker rod enters for 4 times in oil pipe 6, the upper end of sucker rod 4 is through wellhead sealing device 1, oil reservoir 15 communicates with sleeve pipe 5, the bottom of oil pipe 6 connects screen casing 11 successively, packer 13, oil well pump 14, the outside suit urceolus 12 of screen casing 11, annular channel 10 is had between screen casing 11 and urceolus 12, linked hole is arranged at the top of screen casing 11, described linked hole is by oil pipe cylinder 8 and described annular channel 10 UNICOM, liquid in the annular space 7 that packer 13 and sleeve pipe 5 fitted seal make sleeve pipe 5 and oil pipe 6 be formed can not flow to the bottom of packer 13, the bottom of sucker rod 4 connects the piston of oil well pump 14.
Under the effect of packer 13, the oil-water mixture that oil well pump 14 is extracted out flow to annular channel 10 from the linked hole screen casing 9, upwards flow from annular space 7 after turning to the bottom flowing to urceolus 12 downwards again and be plucked out of, mixed liquor is when flowing to annular channel 10 and turning to downwards, fluid is separated under the effect of density contrast, isolated crude oil is upwards gathered in oil pipe cylinder 8, makes the inwall of sucker rod 4 and oil pipe 6 be immersed in crude oil, produces lubrication to it.
Also containing natural gas in isolated crude oil, can be released by tubing valve 2, tubing valve 2 can be constant pressure switch valve, is automatically released by the gas that oil pipe cylinder 8 top is assembled when pressure reaches certain value, make the liquid level of crude oil arrive well head, the inwall of sucker rod 4 and oil pipe 6 is completely soaked.
Oil pipe cylinder 8 is the internal channel of oil pipe 6.
