In view of this, the inventor is actively studied and is innovated, and has finally invented a kind of compound Tubing Packer of novel structure, to solve problems of the prior art, makes it more have practicality.
The utility model content
In order to solve the above-mentioned problems in the prior art, the utility model provides a kind of compound Tubing Packer, has the advantages that to set rapid and permanently effective sealing.
In order to solve the problems of the technologies described above, the utility model has adopted following technical scheme:
Compound Tubing Packer comprises the core pipe and is sheathed on axial compression device and packing element assembly on the core pipe, and wherein the packing element assembly is by rise packing element and meet liquid expansion packing element and form of pressure.
Further, described chance liquid expansion packing element comprises vulcanized rubber cylinder and the metal ring that is placed in its end.
Further, described pressure the rise both sides of packing element are respectively equipped with and meet liquid expansion packing element, and press between rise packing element and chance liquid expansion packing element and be provided with spacer ring.
Further, be provided with joint ring between described spacer ring and core pipe.
Further, the two ends of described core pipe be threaded respectively the first joint and the second joint, be arranged with successively compression cylinder, piston, retaining ring, baffle ring, packing element assembly and baffle ring between the first joint and the second joint, fix by shear pin between piston and compression cylinder, formation annular compression chamber between compression cylinder, piston and core pipe, have the radial direction through hole that is communicated with annular compression chamber on the core pipe, the retaining ring is the split ring to packing element assembly direction single-way moving, is positioned at the groove of pistons end.
Further, have the teeth that tilt to packing element assembly direction on described core pipe, have on the retaining ring with teeth on the core pipe and match, and the opposite tooth line of incline direction.
Compared with prior art, the beneficial effects of the utility model are:
The utility model solves the technical barrier of pressing the formula packer that rises can't realize permanently effective sealing.Compound Tubing Packer of the present utility model has concurrently and sets fast and the characteristics of permanently effective packing, thereby reduces the common pressure long-term underground work failure risk of formula packer that rises, and has reduced and has bored the problem of completion practice Ri Feigao, thereby saved operating cost.
Description of drawings
Fig. 1 is that the structure of compound Tubing Packer of the present utility model is cutd open figure;
Fig. 2 is I section in Fig. 1, i.e. the retaining ring enlarged drawing of section that combines with the core pipe.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, but not as to restriction of the present utility model.
Fig. 1 is that the structure of compound Tubing Packer of the present utility model is cutd open figure.As described in Figure 1, compound Tubing Packer comprises core pipe 2 and is sheathed on axial compression device and packing element assembly on the core pipe, and wherein the packing element assembly is met liquid expansion packing element 8 and second and met liquid expansion packing element 8 ＇ and form by pressure rise packing element 10 and pressing first of packing element 10 both sides of rising.Wherein, the first chance liquid expansion packing element 8 and second is met liquid expansion packing element 8 ＇ and is made of vulcanized rubber cylinder 81 and the metal ring 82 that is placed in its end respectively, is formed on metal ring 82 by the vulcanization of rubber.
The two ends of core pipe 2 are threaded respectively and are arranged with successively compression cylinder 3, piston 4, retaining ring 6, the first baffle ring 7, packing element assembly and the second baffle ring 17 on core pipe 2 between the first joint 1 and the second joint 11, the first joints 1 and the second joint 11.Fixing by shear pin 5 between piston 4 and compression cylinder 3.Shear pin 5 is four, upwards evenly distributes in week.One end of piston 4 stretches between compression cylinder 3 and core pipe 2, and and compression cylinder 3 and core pipe 2 between joint ring is set respectively, realize that sealed sliding is dynamically connected.Be similarly and realize sealing, also be provided with sealing ring between compression cylinder 3 and core pipe 2.Between compression cylinder 3, piston 4 and core pipe 2, formation annular compression chamber 12, have the radial direction through hole 13 that is communicated with annular compression chamber 12 on core pipe 2.Retaining ring 6 is positioned at the groove of piston 4 ends.Can effectively reduce length dimension, and extend the application life of retaining ring 6.Retaining ring 6 is the split ring to packing element assembly direction single-way moving.Fig. 2 is the combine enlarged drawing of section of retaining ring 6 and core pipe 2.As shown in Figure 2, have the teeth that tilt to packing element assembly direction on core pipe 2, have on retaining ring 6 with teeth on core pipe 2 and match, and the opposite tooth line of incline direction.Because retaining ring 6 is split ring, and teeth and the tooth line of the inclination that matches between retaining ring 6 and core pipe 2, make retaining ring 6 possess the unidirectional self-lock function.The rise both sides of packing element 10 of pressure are respectively equipped with first and meet liquid expansion packing element 8 and second and meet liquid expansion packing element 8 ＇, the first chance liquid expansion packing element 8 and pressure rise and are provided with the first spacer ring 9 between packing element 10, press the packing element 10 and second that rises to meet between liquid expansion packing element 8 ＇ and are provided with the second spacer ring 9 ＇.Be respectively equipped with joint ring between the first spacer ring 9 and the second spacer ring 9 ＇ and core pipe 2.
the course of work of the present utility model is as follows: after compound Tubing Packer lower going-into-well of the present utility model, to the interior pressurization of core pipe 2, and enter into annular compression chamber 12 by radial direction through hole 13 and act on piston 4, after reaching setting pressure, shear pin 5 is cut off, piston 4 drives retaining ring 6 and moves, rise packing element 10 and two chance liquid expansion packing elements 8 are pressed in final compression, 8 ＇, pressure packing element 10 external diameters that rise increase, thereby realize the annular space packing, teeth and tooth line due to the inclination that matches between retaining ring 6 and mandrel 2, and retaining ring 6 is 1 split ring, so retaining ring 6 can be along the inclined-plane single-way moving of teeth, play retaining, locked piston 4 effects, when the packing time seal clearance occurs between than long packing element type and annular space, meet liquid expansion packing element 8,8 ＇ owing to contact with downhole fluid for two, volume can further expand, and plays auto-compensation, and the raising sealability realizes the self compensation purpose.Extended the packing time.
Above embodiment is only exemplary embodiment of the present utility model, is not used in restriction the utility model, and protection domain of the present utility model is defined by the claims.Those skilled in the art can make various modifications or be equal to replacement the utility model in essence of the present utility model and protection domain, this modification or be equal to replacement and also should be considered as dropping in protection domain of the present utility model.
