Abstract
The utility model relates to a packer used for plugging a steam injection well in oil-field operation, particularly a high-strength seal steam-injection packer which comprises a central tube (10), an upper adapter (1), a high-strength sealing element (3) and a hydraulic cylinder (9). When in use, the fluid inside the hydraulic cylinder (9) expands under high temperature of the injected steam to push the piston to compact the high-strength sealing element (3), and simultaneously the steam pressure inside the oil pipe is transferred to the hydraulic cylinder (9) through the small holes on the central tube (10) to push the piston upward, so as to enable the high-strength sealing element (3) to be locked by the locking sleeve without rebound, as a result, the casing space is sealed for a long time period. The high-strength seal steam-injection packer can seal the casing space for a long time period without needing slips, thereby preventing the blockage of the well; and can prevent the seeping and leakage during the underground long-term steam injection operation since the high-strength sealing element is made by extrusion molding of combination of various high-temperature resistant materials.
Description
Technical field
The utility model relates to the packer that uses in the steamed well section seal in the oil field operation, especially: high-strength sealing steam injection packer.
Background technology
At present, in oil field operation, need use packer during steamed well section seal, and what often adopt is slip-type packer and temperature-sensitive packer; Though slip-type packer can carry out well section seal, because heat-proof string has crawl in the steam injection process, seal leaks easily, and the sealing time is short, the easy Ka Jing of slips; Adopt poly-PTFE to be pressed into shell-like and the encapsulant of temperature-sensitive packer, poly-tetrafluoro cover is easy to be extruded bad in the steam injection process of down-hole, can not keep long sealing, annotate vapour after three days casing pressure and temperature all very high, therefore make troubles to steam injection work; And better packer does not also occur.
Summary of the invention
Summary of the invention of the present utility model is, a kind of high-strength sealing steam injection packer is provided, and this packer design has hydraulic cylinder, piston and high-strength sealing spare, utilizes the liquid in the steam injection temperature expansion hydraulic cylinder, the promotion piston compresses high-strength sealing spare and shunts in a well, for a long time enclosure space; To achieve these goals, the utility model is achieved in that high-strength sealing steam injection packer, by: central tube, top connection, high-strength sealing spare, hydraulic cylinder etc. are formed, and it is characterized in that: top connection, high-strength sealing spare and hydraulic cylinder are installed on the central tube; Wherein: high-strength sealing spare be by: poly-tetrafluoro, copper powder, graphite, carbon fiber are arranged net, nickel wire, etc. anti-heat insulating material compound suppressing moulding, outer wrapping sheet copper guard shield; Central tube is the center connector of packer, in the upper end of central tube the top connection that connects tubing string is installed, and upper baffle ring is installed in the centre of top connection and two cover high-strength sealing spares, is used for blocking the thrust that high-strength sealing spare makes progress; Between two cover high-strength sealing spares, adopt spacer ring to cut off, in an other side of high-strength sealing spare a spacer ring is installed again and is used for shelves and lives the downward thrust of high-strength sealing spare; In the lower end of high-strength sealing spare is hydraulic cylinder, and hydraulic cylinder is packed into, and liquid is later to be fixed on the central tube by the hydraulic cylinder seat; On the central tube of hydraulic cylinder the inside, the deblocking seat is installed, the deblocking pin is installed on the deblocking seat; The deblocking seat is connected with the locking cover, and locking puts piston is installed; Central tube design in the hydraulic cylinder the inside has aperture; High-strength sealing steam injection packer is when doing seal operation: promote piston by liquid in the steam injection temperature expansion hydraulic cylinder and compress high-strength sealing spare, the oil pipe steam injection pressure can import cylinder pushes piston stroking upward compression high-strength sealing spare by the aperture above the central tube into simultaneously, the pressure of annotating vapour does not stop piston and will push the bigger pressure of high-strength sealing spare to, and pinned not by the locking cover can resilience for high-strength sealing spare when stopping to annotate vapour; So just can seal ring set space body for a long time; Strong sealing steam injection packer is when doing deblocking work: cut off locking deblocking pin, high-strength sealing spare is return original duty.The utility model high-strength sealing steam injection packer can seal the ring set space for a long time, because therefore no slips or not the phenomenon can not take place yet; Owing to adopted high-strength sealing spare by the synthetic extrusion modling of multiple exotic material, thus can be in the long steam injection work in down-hole no seepage and no leakage.
Description of drawings
Accompanying drawing is the half sectional view of high-strength sealing steam injection packer.
The specific embodiment
Below with reference to the accompanying drawings (as shown in the figure) the utility model is described further: high-strength sealing steam injection packer, by: central tube 10, top connection 1, high-strength sealing spare 3, hydraulic cylinder 9 etc. are formed, and it is characterized in that: top connection 1, high-strength sealing spare 3 and hydraulic cylinder 9 are installed on the central tube 10; At first adopt: poly-tetrafluoro, copper powder, graphite, carbon fiber are arranged net, nickel wire, etc. anti-heat insulating material compound suppressing become high-strength sealing spare 3, outer wrapping sheet copper guard shield again; Adopt round steel to be made as the center connector central tube 10 that design has the packer of aperture 12, the top connection 1 that connects tubing string is installed in upper end at central tube 10, upper baffle ring 2 is installed in the centre of top connection 1 and two cover high-strength sealing spares 3, with an other side spacer ring 4 is installed also between two cover high-strength sealing spares 3; Hydraulic cylinder 9 is installed in lower end at high-strength sealing spare 3, and hydraulic cylinder 9 is packed into, and liquid is later to be fixed on the central tube 10 by hydraulic cylinder seat 11; The deblocking seat 5 of deblocking pin 6 is installed on the central tube 10 of hydraulic cylinder 9 the insides, and deblocking seat 5 is connected and installed with piston 8 locking cover 7.
