Abstract
A fire and high pressure resistant compressing packer which is characterized in that at one end or both ends of the packer, is bonded with a plastic shoulder protector made of fire resistant plastic or rubber plastic blending polymer material which can be vulcanization molded with the packer. The utility model adds plastic shoulder on the packer and the fire resistant plastic that the shoulder uses is of high strength, good ductibility and plasticity and can give overall protection to the packer, ensuring the packer of high pressure-bearing capability, good seal effect, long service life, and simple use.
Description
Technical field
The utility model relates to a kind of high temperature and high pressure resistant compression packing element, is specially adapted to separated-zone water infection oil field, well-flushing, well cementation, completion, acidifying and water blockoff etc.
Background technology
Packer is a kind of key tool of oil field down-hole oil production, is widely used in several work purpose needs such as oil field dispensing, separate zone stimulation, oil production by layer, mechanical pipe water blockoff.Packing element is as the chief component of packer, and its quality directly influences the normal result of use of packer, application life etc., decisive role in packer.When packing element bore High Pressure Difference in high temperature oil, the packing element shoulder is easily outstanding to be increased, even breaks, and makes the packing element seal failure, thereby caused the withstand voltage difference of packer low, application life is short.Therefore, at present normal what use is to add protection structures such as metal ring, wire lath at the two ends of packing element, at pressure reduction when not being very high; satisfied instructions for use, but along with the rising of pressure reduction, the packing element shoulder still can not change easily outstanding distortion; even the shortcoming of tearing, cause packing element to damage.
The utility model content
Technology of the present utility model is dealt with problems: overcome the deficiencies in the prior art, the compression type packer tubling of a kind of high temperature resistant (the highest 180 ℃) and high pressure (the highest 80MPa) is provided, its sealing is reliable, long service life.
The technical solution of the utility model is: a kind of high temperature and high pressure resistant compression packing element, its characteristics are: bonding resistant to elevated temperatures and and the packing element plastics shoulder protector of sulfidization molding together in the one or both sides of packing element.Because this shoulder protector coated with adhesive; with packing element sulfidization molding together; make both firm sticking together; solved the packing element disadvantage that shoulder is easily given prominence to drawing crack in the pressure-bearing process effectively; thereby protected packing element; improve packing element and born the ability of high pressure and the stability of sealing, prolonged the application life of packing element.
Described plastics shoulder protector is resistant to elevated temperatures plastics or rubber plastic blend macromolecular material, as polyamide or Merlon or polysulfones or polyimides.
Compared with the prior art the utility model has following advantage: owing to be added with the plastics shoulder protector; the high-temperature resistance plastice that this shoulder protector adopts has very high intensity; ductility and certain elasticity preferably; can comprehensively protect packing element; guarantee packing element bearing capacity height; good sealing effect, long service life, easy to use.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model is made up of packing element 1 and the plastics shoulder protector 2 that is adhered to 1 two shoulders of packing element, plastics shoulder protector 2 is processed into bowl-type, bond together by glue and packing element 1, the material of packing element 1 is hydrogenated nitrile-butadiene rubber HNBR or fluorubber FKM etc., the material of plastics shoulder protector 2 is a polyamide, or Merlon, or polysulfones, or polyimides, add and man-hour Kai Muluoke 205 is coated in plastics shoulder protector 2 inside, put into mould, inject rubber, at 160 ± 5 ℃, 20MPa down and packing element 1 sulfidization molding together, the packing element 1 after the moulding can be in 180 ℃ of oil of high temperature the high pressure of anti-8～80MPa.
Claims (3)
1, a kind of high temperature and high pressure resistant compression packing element is characterized in that: bonding resistant to elevated temperatures and and the packing element plastics shoulder protector of sulfidization molding together in the one or both sides of packing element.
2, high temperature and high pressure resistant compression packing element according to claim 1 is characterized in that: described plastics shoulder protector is resistant to elevated temperatures plastics or rubber plastic blend macromolecular material.
