Abstract
The utility model discloses a well logging oiling sealing head lubricating device which comprises a sealing head and a sealing press wire which is connected in an inner cavity of the sealing head through threads. Vertically-through steel wire holes are formed in the center of the sealing head and the center of the sealing press wire. A lubricating passage communicated with the steel wire through holes is formed inside the sealing head. A sealing rubber block is compressed between the lower end of the sealing press wire and the inner cavity of the sealing head. A vertically-through steel wire hole is formed in the center of the sealing rubber block. The well logging oiling sealing head lubricating device is simple in structure, convenient to operate and suitable for high-low pressure gas wells and high-low pressure water wells, effectively reduces friction resistance of steel wires to the sealing rubber block at uplifting and down placing time, well protects the sealing rubber block so as to prolong the service life of the rubber block, and is good in sealing effect.
Description
Technical field
The utility model relates to lubricating arrangement, and is specifically a kind of for the on-the-spot height of petroleum industry setting-out, when gas well is tested, the well logging oiling seal head lubricating arrangement of steel wire in the lubricated pit shaft during put-on and delegated steel wire.
Background technology
At present lubricated to the lubricated ground of adopting mostly of steel wire in the steel wire test process, be exactly when steel wire down, steel wire is by the ground G.I.H, but on lubricated in well when carrying steel wire operation and especially can not solve steel wire effectively when well, gas well test.
Summary of the invention
The purpose of this utility model is to provide well logging oiling seal head lubricating arrangement, solve effectively carry steel wire operation especially can not be in the defective of the lubricated steel wire of border well when well, gas well test.
In order to reach above-mentioned purpose, the utility model has adopted following technical scheme, well logging oiling seal head lubricating arrangement, comprise seal head, sealing silk pressing, described sealing silk pressing is connected the seal head inner chamber by engage thread, the center of described seal head and sealing silk pressing offers the steel wire perforation of up/down perforation, and described seal head inside offers the lubrication channel that is communicated with the steel wire perforation.
Described lubrication channel is tunneled to the seal head opening of external wall always, and is connected to filling pump at opening by flexible pipe.
Also compressed the caulking gum piece between described sealing silk pressing lower end and the seal head inner chamber, described caulking gum piece center also offers the steel wire perforation of up/down perforation.
The steel wire perforation axis that open at described seal head, sealing silk pressing, caulking gum piece center is consistent.
Described sealing silk pressing top also offers oil storage tank, and steel wire is through oil storage tank, and oil storage tank is connected with the sealing silk pressing.
Described seal head outer wall offers sealed groove, and sealing ring is set in the groove.
Described seal head lower end outer wall offers the screw thread that is connected with lubricator.
Compared to prior art, the utlity model has following beneficial effect:
The utility model is simple in structure, easy to operate; be applicable to high-low pressure gas well, well; steel wire is to the frictional resistance of caulking gum piece when reducing put-on and delegated effectively; thereby better protect the caulking gum piece prolong service time of block rubber; sealing effectiveness is better, has promotional value in the oil field.
Description of drawings
Fig. 1 is well logging oiling seal head lubricating arrangement structural representation of the present utility model.
Among the figure: oil storage tank 1, sealing silk pressing 2, caulking gum piece 3, lubrication channel 4, seal head 5, sealing ring 6.
The specific embodiment
Relevant detailed description of the present utility model and technology contents, conjunction with figs. is described as follows, however accompanying drawing only provides the usefulness of reference with explanation, and the utility model is limited.
With reference to accompanying drawing 1, well logging oiling seal head lubricating arrangement, comprise seal head 5, sealing silk pressing 2, described sealing silk pressing is connected the seal head inner chamber by engage thread, the center of described seal head and sealing silk pressing offers the steel wire perforation of up/down perforation, and described seal head inside offers the lubrication channel 4 that is communicated with the steel wire perforation.Described lubrication channel is tunneled to the seal head opening of external wall always, and is connected to filling pump at opening by flexible pipe.
Also compressed caulking gum piece 3 between described sealing silk pressing lower end and the seal head inner chamber, blanket gas, well prevent that borehole fluid from flowing out, and described caulking gum piece center also offers the steel wire perforation of up/down perforation.The steel wire perforation axis that open at described seal head, sealing silk pressing, caulking gum piece center is consistent.Described sealing silk pressing top also offers oil storage tank 1, and steel wire is used for lubricating the well logging steel wire in the well through oil storage tank, and oil storage tank is connected with the sealing silk pressing.Described seal head outer wall offers sealed groove, and sealing ring 6 is set in the groove.Described seal head lower end outer wall offers the screw thread that is connected with lubricator.
The oiling seal lubrication device of will logging well is connected on the lubricator by junction button, steel wire is passed successively the sealing silk pressing 2 of well logging seal lubrication device, caulking gum piece 3, the endoporus that seal head 5 axis are consistent, be connected high-pressure hose on the lubrication channel 4 of well logging seal lubrication device by junction button, high-pressure hose is connected on the filling pump, transfer the oil lubrication steel wire in the oil storage tank 1 that steel wire sealing silk pressing is provided with, when on filling pump pressurization when carrying steel wire, lubrication oil enters in the lubrication channel 4 by high-pressure hose, lubrication oil is sprayed on to be carried on the steel wire, thereby has lubricated steel wire.
The above only is preferred embodiment of the present utility model, and non-in order to limit claim of the present utility model, other use the equivalence of patent spirit of the present utility model to change, and all should all belong to claim of the present utility model.
