Description

A kind of packer
Technical field
The utility model belongs to oil recovery machiner technical field, and in particular to a kind of packer.
Background technique
With the rapid development of our country's economy, the demand of the energy such as petroleum, natural gas is continuously increased, and packer exists There is more application in oil field prospecting and development process.Packer refers to elastic sealing elements, and insulates various sizes whereby Annular space between tubing string and wellbore and between tubing string, and completely cut off payzone, (note) liquid, the underground work of protection sleeve pipe are produced with control Tool.In the process that packer is gone into the well, the packing element of packer inevitably occurs to scratch with the borehole wall to rub, and the damage of packing element The operating pressure decline that may cause packer, does not reach requirement.For the damage for avoiding packing element, frequently with method have using hard Higher packing element is spent, but the sealing effect between packing element and the borehole wall can be reduced while improving packing element hardness, and but also Setting force greatly improves.Therefore, it is badly in need of a kind of packer for being able to solve existing issue.
Utility model content
The purpose of this utility model is in view of the deficiencies of the prior art, to provide a kind of packer, the packing element of the packer is not It is easy to damage.
The utility model provides following technical solution:
A kind of packer, including packing element, top connection and lower contact, the packing element, the top connection and the lower contact sulphur Chemical conversion one, the end of the packing element is equipped with tapered surface, is arranged with protective case respectively at the tapered surface of the packing element end, described Protective case is embedded in metal mesh, and the both ends of the metal mesh are respectively equipped with the first annulus and the second annulus, first annulus Diameter be less than second annulus diameter, the protective case outer wall be equipped with several protrusions, the top connection and it is described under connect Head is equipped with the limit plate of the fixed protective case.
Preferably, the packing element outer wall is equipped with several annular grooves.
Preferably, the material that the metal mesh, first annulus and second annulus use is steel wire.
Preferably, the protective case is coated with release agent layer close to the packing element on one side.
Preferably, the top connection and the lower contact is equipped with screw thread, the limit plate and the top connection and described Lower contact is threadedly coupled.
The beneficial effects of the utility model are: the utility model is equipped with protective case on packing element, it can be used for protecting packing element, subtract The damage of few packing element;The utility model is embedded with metal mesh in protective case, can increase the hardness and strength of protective case, and metal The diameter of the first online annulus helps for protective case to be fixed on packing element less than the diameter of the second annulus;Top connection is under The limit plate being threadedly coupled on connector helps to further fix protective case.
Detailed description of the invention
Attached drawing is used to provide a further understanding of the present invention and illustrates.
Fig. 1 is the structural schematic diagram of the utility model;
Fig. 2 is the enlarged diagram in Fig. 1 at A.
In the figure, it is marked as 1, packing element;2, top connection;3, lower contact;4, protective case;5, metal mesh;6, the first annulus;7, Two annulus;8, raised;9, limit plate;10, annular groove.
Specific embodiment
As depicted in figs. 1 and 2, a kind of packer, including packing element 1, top connection 2 and lower contact 3, packing element 1,2 and of top connection Lower contact 3 vulcanizes integrally, and 1 outer wall of packing element is equipped with several annular grooves 10, can be used as stress relief grooves, so that packing element 1 fills Divide setting and recycling.The end of packing element 1 is equipped with tapered surface, is arranged with protective case 4 respectively at the tapered surface of 1 end of packing element, protects Set 4 the material used for rubber or resin, protective case 4 is coated with release agent layer close to packing element 1 on one side, prevent protective case 4 and Packing element 1 is sticked together, and facilitates the installation and replacement of protective case 4, and protective case 4 is embedded in metal mesh 5, the both ends point of metal mesh 5 Not She You the first annulus 6 and the second annulus 7, the diameter of the diameter of the first annulus 6 less than the second annulus 7, the circle of metal mesh 5, first For the material that ring 6 and the second annulus 7 use for steel wire, 4 outer wall of protective case is equipped with several raised 8.In top connection 2 and lower contact 3 Limit plate 9 equipped with fixed protective case 4, top connection 2 and lower contact 3 are equipped with screw thread, limit plate 9 and top connection 2 and lower contact 3 It is threadedly coupled.The screw thread of top connection 2 and lower contact 3 can be also used for connecting on other components of packer.
The utility model is equipped with protective case 4 on packing element 1, can be used for protecting packing element 1, reduces the damage of packing element 1;This is practical It is novel that metal mesh 5 is embedded in protective case 4, the hardness and strength of protective case 5 can be increased, and the first annulus 6 on metal mesh 5 Diameter less than the diameter of the second annulus 7, help for protective case 4 to be fixed on packing element 1;Screw thread in top connection 2 and lower contact 3 The limit plate 9 of connection helps to further fix protective case 4.
The foregoing is merely the preferred application cases of the utility model, are not intended to limit the utility model, although reference The utility model is described in detail in previous embodiment, for those skilled in the art, still can be right Technical solution documented by foregoing embodiments is modified or equivalent replacement of some of the technical features.It is all Within the spirit and principles of the utility model, it is practical new to should be included in this for any modification, equivalent replacement, improvement and so on Within the protection scope of type.
