Description
Technical field
The present invention 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 Castor Oil abrasionproof oil rig.
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.From the method for above several solution sucker rod, oil pipe wear problem, although achieve certain effect, do not tackle the problem at its root.Therefore, sucker rod, oil pipe wear problem are still serious.
Summary of the invention
The object of this invention is to provide a kind of Castor Oil abrasionproof oil rig, overcome above-mentioned Problems existing, prevent the wearing and tearing between sucker rod and oil pipe, improve its application life, director's oil well production cycle, improve oil well economic benefit.
The technical solution adopted in the present invention is: comprise wellhead sealing device, tubing valve, sleeve valve, sucker rod, sleeve pipe, oil pipe, down-hole sealer, sealed tube, screen casing, 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, enters under sucker rod in oil pipe, and the upper end of sucker rod is through wellhead sealing device, oil reservoir communicates with sleeve pipe, the bottom connecting downhole sealer successively of oil pipe, screen casing, packer, oil well pump, 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, screen casing there is sieve aperture, described sieve aperture will be pumped delivery side of pump and annular space UNICOM, the bottom of sucker rod connects successively under after the plunger of sealed tube and oil well pump and enters in oil pipe, sealed tube arrives in down-hole sealer and is mated sealing, is mated sealing in the pump barrel that the plunger of oil well pump enters oil well pump.
Install ball-and-seat in sealed tube, the effect of described ball-and-seat allows the liquid of the oil pipe cylinder in oil pipe to flow through, and stops passing through from lower well liquid.
The invention has the beneficial effects as follows: in oil pipe cylinder, inject lubrication oil, the well liquid of oil well pump extraction flow in annular space through the linked hole of screen casing and flows out from sleeve valve, lubricating condition is had between sucker rod and oil pipe, substantially there is not the problem of sucker rod, oil pipe wearing and tearing, therefore the present invention can reach purpose of design, overcome problems of the prior art, greatly can extend the production cycle of pumpingh well, there is significant economic benefit.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.
Detailed description of the invention
Be described below in conjunction with accompanying drawing 1 pair of embodiments of the invention.
As shown in Figure 1, embodiments of the invention comprise wellhead sealing device 1, tubing valve 2, sleeve valve 3, sucker rod 4, sleeve pipe 5, oil pipe 6, down-hole sealer 9, sealed tube 10, screen casing 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, the upper end of sleeve pipe 5 and the upper end packing of oil pipe 6, not UNICOM, oil reservoir 15 communicates with sleeve pipe 5, the bottom connecting downhole sealer 9 successively of oil pipe 6, screen casing 12, packer 13, oil well pump 14, packer 13 and sleeve pipe 5 seal sleeve pipe 5 and oil pipe 6 are formed annular space 7 in liquid can not flow to the bottom of packer 13, the specifications and models of packer 13 are selected according to sleeve, under after design attitude, handle packer 13 setting, packer 13 just seals with sleeve pipe 5, screen casing 12 there is sieve aperture, described sieve aperture is by the outlet of oil well pump 14 and annular space 7 UNICOM, the bottom of sucker rod 4 connects successively under after the plunger of sealed tube 10 and oil well pump 14 and enters in oil pipe 6, the upper end of sucker rod 4 is through wellhead sealing device 1, sealed tube 10) arrive in down-hole sealer 9 and be mated sealing, sealing is mated in the pump barrel that the plunger of oil well pump 14 enters oil well pump 14, during work, when sucker rod 4 drives the plunger reciprocates of sealed tube 10 and oil well pump 14, sealed tube 10 is all the time in down-hole sealer 9.
Further measure of the present invention is, installs ball-and-seat 11 in sealed tube 10, and the effect of described ball-and-seat 11 allows the liquid of the oil pipe cylinder 8 in oil pipe to flow through, and stops passing through from lower well liquid.
The present invention is in well after installation, lubrication oil is squeezed into from tubing valve 2, lubrication oil is made to be full of oil pipe cylinder 8, when squeezing into lubrication oil, the well liquid in oil pipe cylinder 8 is discharged by from ball-and-seat 11, and making in oil pipe cylinder 8 is all lubrication oil, during production, the well liquid extracted out can not arrive in oil pipe cylinder 8 under the effect of ball-and-seat 11, makes sucker rod be fully immersed in lubrication oil, and sucker rod 4 and oil pipe 6 can not be worn.
Because of lubrication oil non-corrosiveness, therefore the present invention also can prevent sucker rod 4, oil pipe 6 is corroded.
According to pump structure and pump footpath size, a connecting rod between the plunger of oil well pump and sealed tube, can be connect.
Oil pipe cylinder 8 is the internal channel of oil pipe 6.
