Abstract
The utility model discloses a high-pressure resistance packer with long service life, which is mainly composed of an upper joint, a rubber cylinder, a central tube, a seat unsealing mechanism and a lower joint, wherein one bowl-shaped spring is arranged on one side or both sides of the rubber cylinder. Because the bowl-shaped spring is added to one side or both of the two sides of the rubber cylinder in the utility model, the problem of protruding shoulders of a packer rubber cylinder can be effectively solved; thereby, the rubber cylinder is protected, the sealing and high-pressure bearing abilities can be increased, the service life of the packer can be extended, and the manufacturing cost can be saved.
Description
The utility model relates to a kind of packer, is specially adapted to separated-zone water infection oil field, well-flushing, acidifying and water blockoff.
Packer is used in the oil field in the oil field dispensing of being everlasting, water injection well card water blockoff, separate zone stimulation and Casing Failure protection at present; because the packing element of packer does not add mechanical protection mostly; though the two ends at the packing element assembly that have add metal ring, metal sheaf, wire lath etc.; but can not play a protective role; when packing element is subjected to High Pressure Difference; its shoulder is outstanding to the low-pressure end direction; along with the rising of pressure reduction and the growth of packing element ageing time; the packing element shoulder is outstanding to be increased; make the packing element seal failure; even break, thereby cause the withstand voltage difference of packer low, application life is short.
The purpose of this utility model is exactly the shortcoming that overcomes prior art, provides a kind of high pressure durable packer.
The purpose of this utility model be achieved in that the durable packer of high pressure by top connection, packing element, central tube, seat is separated sealing mechanism, lower contact is formed, and is provided with the bowl-type spring in the one or both sides of packing element.
The utility model adds the bowl-type spring by the one or both sides at packing element; solved the outstanding disadvantage of packing element shoulder effectively, thereby protected packing element, improved sealing and born the high pressure ability; prolong the application life of packer, saved cost of production.
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is the utility model structural representation;
Among the figure: 1-top connection, 2-spring, 3-packing element, 4-central tube, 5-seat separate sealing mechanism,
The 6-lower contact;
As shown in Figure 1, the durable packer of high pressure is separated packer parts such as sealing mechanism 5, lower contact 6 by top connection 1, packing element 3, central tube 4, seat and is formed, and it is to be provided with bowl-type spring 2 in the one or both sides of packing element 3.Bowl-type spring 2 is a steel material; hardness height, intensity are big; and carried out preservative treatment; corrosion resistance is strong; being complementary of the size of bowl-type spring 2 and packing element 3; it can be assemblied in the one or both ends of one or one group packing element; spring 2 can expose the end at packing element 2; also can be when making packing element 3 that spring 2 is therein hidden; when if 3 of packing elements bear one-way sealing pressure reduction; only need in packing element 3 one end mounting spring 2, when bearing two way seal pressure reduction, must add 2 protections of bowl-type spring at the two ends of packing element 3 as if packing element 3.When packing element 3 compression mounts seal; packing element 3 radial dilatation; bowl-type spring 2 is simultaneously by axial compression; in axial compression; bowl-type spring 2 is radial dilatation also; increase along with axial compression; spring 2 radial dilatation increase; when the outer ring of spring 2 contacts with the down-hole casing inwall; limited by internal surface of sleeve pipe, between packer outer wall and down-hole casing inwall, form the horn-like rigidity conical ring of a spring steel wire stack, block the outstanding annular space of packing element shoulder fully; it is outstanding to make packing element that shoulder can not take place, thereby has protected packing element.When the packer deblocking, axial compression that packing element and spring bear is removed, and packing element and spring rely on itself elasticity to shrink simultaneously, have guaranteed that packer can trip out smoothly from the down-hole.This mode that the bowl-type spring is added in the packing element one or both sides goes for any packer, thus the advantage that reaches high pressure resistant, increases the service life.
Claims (1)
1, the durable packer of a kind of high pressure mainly by top connection (1), packing element (3), central tube (4), seat is separated sealing mechanism (5), lower contact (6) is formed, it is characterized in that: be provided with bowl-type spring (2) in the one or both sides of packing element (3).
