Abstract
The utility model relates to a sucker rod blowout preventer of an oil pumping well, which comprises a wellhead valve connector, valves and a sucker rod, and is characterized in that the wellhead valveconnector is provided with an annular lubricating oil barrel, an anti-corrosion and anti-friction non-metallic flexible working cylinder is assembled in the annular space between the annular lubricating oil barrel and the sucker rod, the inner wall and the outer wall of the working cylinder are respectively provided with an inner annular lubricating oil groove and an outer annular lubricating oilgroove, the wall of the working cylinder is provided with a lubricating oil duct communicating the inner annular lubricating oil groove with the outer annular lubricating oil groove, the inner wall of the lubricating oil barrel is provided with an oil groove, the upper end of the lubricating oil barrel is provided with an oil charging hole, and the annular lubricating oil barrel is in threaded connection with nuts. The utility model has the advantages of solving the problem that oil leaks frequently at the oil wellhead, increasing the production efficiency and output of the oil pumping well and purifying the surrounding environment of the oil pumping well.
Description
Technical field
The utility model belongs to a kind of oil tool of oil well, particularly a kind of pumpingh well sucker rod preventer.
Background technology
The pumpingh well in oil field in process of production, because well head packing and pumpingh well sucker rod after friction after a while, cause the sucker rod surface impaired, and well head reason such as eccentric wear just not, produce wearing clearance, when wellhead back pressure and oil pressure were higher, crude oil can be therefore and the well head that pours out causes leakage, not only cause the severe contamination on ground, and reduce pumpingh well output, and cause the certain economic loss, demand urgently providing a kind of technical measures to solve this problem at present.
The utility model content
The purpose of this utility model provides a kind of pumpingh well sucker rod preventer, solves well mouth of oil well and often produces the problem of leakage of oil, improves pumpingh well production efficiency and output, purifies the pumpingh well surrounding environment.
The purpose of this utility model is achieved by the following technical solution: it comprises the head valve connector, valve and sucker rod, it is characterized in that: the ring-type Lubricating oil barrel is set on the head valve connector, the nonmetal elastic working tube of assembling corrosion-proof wear in the annulus between ring-type Lubricating oil barrel and the sucker rod, the inside-and-outside ring oil-way is set respectively on the inside and outside wall of seating nipple, on the work barrel, the oil leab that is communicated with the inside-and-outside ring oil-way is set, on the inwall of Lubricating oil barrel, offer oil through, the upper end of Lubricating oil barrel is provided with oil filler point, and nut is threaded on the ring-type Lubricating oil barrel.
The utility model advantage: solved well mouth of oil well and often produced the problem of leakage of oil, improved pumpingh well production efficiency and output, purified the pumpingh well working environment.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a seating nipple structure enlarged diagram of the present utility model.
The specific embodiment
See Fig. 1,2, concrete structure is as follows: sucker rod 1 top assembling head valve connector 10 connects valve 2 on the head valve connector 10.Ring-type Lubricating oil barrel 7 is set on head valve connector 10, the nonmetal elastic working tube 9 of assembling corrosion-proof wear in the annulus between ring-type Lubricating oil barrel 7 and the sucker rod 1, material can adopt plastic cement.Twice inside-and-outside ring oil-way 8 is set respectively on the inside and outside wall of seating nipple 9, on the work barrel oil leab 4 that is communicated with inside-and-outside ring oil-way 8 is set, offer oil through 3 on the inwall of Lubricating oil barrel 7, the upper end of Lubricating oil barrel 7 is provided with oil filler point 5.The nut 6 that is threaded on the ring-type Lubricating oil barrel is with fixing elastic working tube 9.
Operating principle: the utility model is assembled on the well head, when pumpingh well is worked, sucker rod pumps, lubrication oil in the Lubricating oil barrel 7 is lubricated with seating nipple 9 inwalls by oil leab 4, the 8 pairs of sucker rods of interior annular oil-way 1 on the oil through on the inwall 3, outer ring oil-way 8, the work barrel, and sucker rod 1 played cooling effect, play the wear-resisting and sealing function that strengthens sucker rod 1 and seating nipple 9.Stop leakage of oil between the two thereby make.
