Abstract
The utility model relates to a well head oiling device can be lubricated to the packing among the pumpingh well polish rod sealing device, improves sealed effect. This device is equipped with oiling mechanism and oil -out including grease gun, grease gun, and grease gun and actuating mechanism and fixed with mount and wellhead assembly are fixed respectively to the both ends of mount, install actuating mechanism's single gear wheel on the power input shaft of oiling mechanism, the oil -out of grease gun is connected with the oil inlet that polish rod sealing device lubricates the mechanism through annotating oil pipe. This device makes the polished rod form the oil film in the motion process to the automatic oil addition of the polish rod sealing device's after improving lubricated mechanism, wearing and tearing between reduction polished rod and the polish rod sealing device packing and with the contact probability of complicated oil to stop the seepage. What change that at present low liquid measure, viscous crude, high special oil well such as moisture exist causes the oil leak phenomenon that the well head packing appears because of the lubricated bad reason of packing. Prolong the life of packing, polished rod, reduced power consumptively, improved sealed effect.
Description
Technical field
This utility model is related to the lubricating arrangement of well head part, particularly a kind of well head oiling device, can be right
Packing lubrication in sealing machine for oil well polish rod, improves sealing effectiveness.
Background technology
The oil well of at present oil field development, because of the impact of the factors such as the decline of stratum energy, water filling, mostly low liquid measure oil well,
Based on high-water-cut oil-producing well and complicated oil well.Low liquid measure oil well because of stratum feed flow reason between go out serious, cause polished rod sealer packing
Dry grinding is serious；High-water-cut oil-producing well, because aqueous higher, cannot form oil film on polished rod, and polished rod sealer packing seepage is serious；Multiple
Miscellaneous oil well is then because oil product problem causes the seepage of well head.With the raising of environmental consciousness, the seriously polluted restriction of this part oil well
Clean manufacturing, increased the labor intensity of worker.
The problem existing for oil well above-mentioned in oil field development, departments at different levels just lift well head sealing effectiveness, extend polished rod
The aspects such as the service life of sealer packing have carried out substantial amounts of technological improvement, such as introduce new-type polished rod sealer, green wood charging tray
Root, oozes the measures such as oil lubricating polished rod and polished rod sealer packing on well head top.But because above-mentioned measure does not fundamentally change
Kind packing and the working condition of polished rod, its effect is poor, not only increases production cost and defines new pollution, such oil well
Leakage problems still do not solve.With the raising to environmental consciousness, this problem has become needs the important of solution in oil field development
Problem.
Content of the invention
For improving the lubricant effect of polished rod and the sealing effectiveness of polished rod sealer, this utility model provides a kind of well head oiling
Device, can rely on the oil filling mechanism of the downlink drive grease gun of polished rod eye, be the lubricating structure automatic filling of polished rod sealer
Lubricating oil, improves the working condition of packing and polished rod, improves sealing effectiveness, environmental protection, reduces the labor intensity of workman.
This utility model is realized in：A kind of well head oiling device includes grease gun, and grease gun is provided with oil filling mechanism
And oil-out, the two ends of fixed mount are fixed grease gun and drive mechanism respectively and are fixed fixed mount with wellhead assembly；To drive
The ratchet of mechanism is arranged on the power input shaft of oil filling mechanism；The oil-out of grease gun passes through oil fuel tube and polished rod seal
The oil-in of device lubricating structure connects.
Compared with prior art, the remarkable result of this device is：The lubricating machine to the polished rod sealer after improving for this device
The automatic oil addition of structure makes polished rod form oil film in motor process, reduces the abrasion between polished rod and polished rod sealer packing
And the contact probability with complicated oil product, thus prevent seepage.Change the special oil well such as low liquid measure, viscous crude, High water cut at present to deposit
Because packing insufficient lubrication reason cause well head packing occur oil leakage phenomenon.
The drive rod that this device passes through to press drive mechanism when oil well rope suspending is descending drives ratchet to rotate, and makes butter
The oil filling mechanism of rifle is the lubricating structure automatic filling lubricating oil of polished rod sealer, realizes the reset of drive rod by spring.Cause
For ratchet by the unidirectional rack drives on drive rod, when polished rod eye is up, unidirectional tooth bar can be upper oblique along ratchet
Face upward sliding, and ratchet does not rotate, grease gun also just no longer oiling.This device does not need additionally to provide power for it,
So under the normal situation producing of oil well, lubricating oil is injected into the lubricating structure of polished rod sealer bottom through grease gun and oil fuel tube
In.In oil well production, polished rod moves back and forth, and when lubricating structure, polished rod surface forms one layer of lubricating oil coherent film, heavy oil wells
Well liquid cannot directly contact energy when lubrication, high-water-cut oil-producing well can be provided unlubricated for polished rod when going out between polished rod, low liquid oil well
Enough offer for polished rod lubricates, and makes different oil wells be attained by lubrication and seal effect.As long as oil well production, grease gun just can carry for it
For lubricating oil, therefore this device can uninterrupted fuel feeding, the up and down motion relying on oil pumper itself is power, forms dynamic both fuel feeding
Stable mode.Effectively improve the lubricating condition of polished rod sealer packing and polished rod, decrease rubbing between packing and polished rod
Wiping power, extends the service life of packing, polished rod, reduces power consumption, improve sealing effectiveness, have good using effect and
Economic benefit.
