Abstract
The invention relates to a packer used in sealing steam injection well sections in oilfield operation in particular to a high-strength sealing steam injection packer; the packer consists of a central tube (10), an upper contact (1), a high-strength sealing element (3), a hydraulic cylinder (9), etc; when the packer works, the liquid pushing piston in the hydraulic cylinder (9) is expanded by the temperature of the steam injected, so as to press the high-strength sealing element (3); meanwhile, the steam injection pressure of an oil pipe can be transmitted to the hydraulic cylinder (9) through a small hole on the central tube (10) to push the piston to move up; the compression high-strength sealing element (3) is locked by a locking sleeve and does not rebound; in this way, the pipe in the space of a loop can be sealed for a long time; the high-strength sealing steam injection packer of the invention can seal the space in the loop for a long time; because of no slip element, no well slipping phenomenon occurs; because of the high-strength sealing element shaped by a plurality of high-temperature resistant materials by synthesis and extrusion, no penetration and leakage occurs after a long time of underground steam injection.
Description
Technical field
The present invention 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 or the also not appearance of packing method.
Summary of the invention
Summary of the invention of the present invention 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 present invention 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; High-strength sealing steam injection packer is when doing deblocking work: cut off locking deblocking pin, high-strength sealing spare is return original state.High-strength sealing steam injection packer of the present invention can seal the ring set space for a long time, because therefore no slips can not block the well phenomenon 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.
