Abstract
A continuous oil pipe dynamic sealer comprises an upper joint, a lower joint, a central pipe, a movable sleeve, a retainer ring, a cylinder liner and a sealing part. The movable sleeve and the cylinder liner are sequentially mounted between the upper joint and the lower joint, the sealing part and the retainer ring are sequentially mounted in the movable sleeve, and the central pipe is mounted in the cylinder liner. The continuous oil pipe dynamic sealer adopts the hydraulic driving mode and the spiral sealing structure to realize good sealing effect, high reliability, convenient control and sealing part replacement during the continuous oil pipe operation, and is extensively applicable to continuous oil pipe sealing technique devices of oil exploration wells.
Description
One, technical field
The utility model relates to oil exploitation down-hole string SLD, particularly a kind of coiled tubing movable sealing device.
Two, background technology
In the oil exploitation, coiled tubing contributes for the down-hole string operation, but it exists following shortcoming or deficiency simultaneously: 1. the sealing performance under the coiled tubing motion state is not good, easily causes the delay even the failure of operation procedure; 2. easily cause body damage and cause the generation of work accident.
Three, summary of the invention
The purpose of this utility model provides a kind of improved coiled tubing movable sealing device, adopts fluid pressure type to drive and spiral hermetically-sealed construction the shortcoming or the deficiency that effectively overcome or avoid existing in the above-mentioned prior art.
Coiled tubing movable sealing device described in the utility model comprises top connection, lower contact, central tube, movable sleeve, baffle ring, cylinder sleeve, seal.Install in turn between described top connection and the lower contact and be connected with movable sleeve and cylinder sleeve, seal and baffle ring are installed in the movable sleeve in turn, central tube is installed in the cylinder sleeve.
Wherein, described central tube upper end is connected with baffle ring, and the lower end seals with the lower contact inwall mutually by " O " shape seal.Described central tube top seals by " O " shape seal mutually with cylinder sleeve.Described central tube middle part is provided with outer lug boss, and this outer lug boss external surface is equipped with " O " shape seal, seals mutually with inner surface of cylinder liner.Described top connection bottom is provided with outer step, matches with the interior step of movable sleeve.Described cylinder sleeve was provided with opening.Opening excessively on the described cylinder sleeve is two, lays respectively at the upper and lower of " O " shape sealing surface of sealing of installing with central tube middle part outer lug boss external surface.
The utility model has following advantage compared with prior art:
1, adopt fluid pressure type to drive good sealing effect, good reliability;
2, adopt spiral hermetically-sealed construction, control is convenient, can change seal in the coiled tubing operation process.
Four, description of drawings
Accompanying drawing is a kind of example structure schematic diagram of the present utility model
Five, the specific embodiment:
Consult accompanying drawing, a kind of coiled tubing movable sealing device comprises top connection 1, lower contact 7, central tube 6, movable sleeve 3, baffle ring 4, cylinder sleeve 5, seal 2.Install in turn between top connection 1 and the lower contact 7 and be connected with movable sleeve 3 and cylinder sleeve 5, seal 2 and baffle ring 4 are installed in the movable sleeve 3 in turn, central tube 6 is installed in the cylinder sleeve 5.
