Abstract
The utility model discloses a kind of for the hydraulic packer in oil and gas exploitation field, solves existing packer and can not realize repeatedly setting problem.Its technical scheme: top connection lower end inside and central tube are threaded connection, outside and piston are threaded connection, and piston bush lower end and glue tube base are threaded connection; Packing element and spacer ring a are alternately assemblied on glue tube base from top to bottom successively, and end in spacer ring b; Neck bush upper end and glue tube base are threaded connection, and lower end and jump ring are threaded connection; Clip spring seat is placed between jump ring and transition joint, and transition joint upper end and central tube lower end are threaded connection; Transition joint lower end is connected with lower contact, and outer shell is placed between urceolus and transition joint; Sleeve, throttle valve element, spring, baffle ring are stuck between transition joint and lower contact successively.The utility model can realize repeatedly setting, and can not lose efficacy or potential safety hazard because of carrying out repeatedly setting generation packer.
Description
Technical field
The utility model relates to a kind of for the hydraulic packer in oil and gas exploitation field.
Background technology
In oil field operation, carry out zonal water plugging oil recovery technique to the petroleum resources of different oil reservoir, envelope falls high aquifer formation, is the effective ways controlling well water rising.Separate stratum fracfturing oil recovery technique will use packer, and the packer of existing kind can not realize repeatedly setting usually in oil recovery, is generally in setting procedure, and encapsulant expands, and seal tubing annulus, during deblocking, lock ring unlocks by upper lifting pipe post.For preventing midway setting before setting, needing to fix with pin, time setting, utilizing tubing string self gravitation to be cut off by pin, but irreversible during this operation.Some packer can carry out repeatedly setting, but also there will be operation hidden danger.
Summary of the invention
The purpose of this utility model is: can not realize repeatedly setting for solving existing packer, even if can the setting problem that also there is operation hidden danger, and the packer that spy provides fluid pressure type repeatedly to set.
For achieving the above object, the technical solution adopted in the utility model is: the packer that fluid pressure type can repeatedly set, by top connection, piston bush, piston, glue tube base, spacer ring a, spacer ring b, urceolus, jump ring, neck bush, clip spring seat, central tube, end sealing mat, outer shell, transition joint, lower contact, sleeve, throttle valve element, spring, baffle ring forms, it is characterized in that top connection lower end inside and central tube are threaded connection, outside and piston are threaded connection, piston bush lower end and glue tube base are threaded connection, and make Piston assembling between top connection and piston bush, piston bush circumference has multiple uniform through hole, packing element and spacer ring a are alternately assemblied on glue tube base from top to bottom successively, and end in spacer ring b, neck bush upper end and glue tube base are threaded connection, and lower end and jump ring are threaded connection, the through hole that neck bush top has multiple circumference uniform, and jump ring circumference has multiple " U " shape groove, urceolus circumference has multiple uniform through hole, and clip spring seat is placed between jump ring and transition joint, and transition joint upper end and central tube lower end are threaded connection, transition joint lower end is connected with lower contact, and outer shell is placed between urceolus and transition joint, sleeve, throttle valve element, spring, baffle ring are stuck between transition joint and lower contact successively.
The beneficial effects of the utility model be can realize repeatedly setting, and can not because of carry out repeatedly setting generation packer lost efficacy or potential safety hazard.

Fig. 1 is the structural representation of the packer that the utility model fluid pressure type can repeatedly set.
In figure: 1. top connection, 2. piston, 3. piston bush, 4. glue tube base, 5. central tube, 6. packing element, 7. spacer ring a, 8. spacer ring b, 9. neck bush, 10. urceolus, 11. jump rings, 12. clip spring seats, 13. outer shells, 14. transition joints, 15. lower contacts, 16. throttle valve elements, 17. sleeves, 18. springs, 19. baffle rings.
Detailed description of the invention
With reference to the accompanying drawings, the packer that fluid pressure type can repeatedly set, by top connection, piston bush, piston, glue tube base, spacer ring a, spacer ring b, urceolus, jump ring, neck bush, clip spring seat, central tube, end sealing mat, outer shell, transition joint, lower contact, sleeve, throttle valve element, spring, baffle ring forms, it is characterized in that top connection 1 lower end inside and central tube 5 are threaded connection, outside and piston 3 are threaded connection, piston bush 2 lower end and glue tube base 4 are threaded connection, and make piston 3 be assemblied between top connection 1 and piston bush 2, piston bush 2 circumference has multiple uniform through hole, packing element 6 and spacer ring a7 are alternately assemblied on glue tube base 4 from top to bottom successively, and end in spacer ring b8, neck bush 9 upper end and glue tube base 4 are threaded connection, and lower end and jump ring 11 are threaded connection, the through hole that neck bush top has multiple circumference uniform, and jump ring 11 circumference has multiple " U " shape groove, urceolus 10 circumference has multiple uniform through hole, and clip spring seat 12 is placed between jump ring 11 and transition joint 14, and transition joint 14 upper end and central tube 5 lower end are threaded connection, transition joint 14 lower end is connected with lower contact 15, and outer shell 13 is placed between urceolus 10 and transition joint 14, sleeve 17, throttle valve element 16, spring 18, baffle ring 19 are stuck between transition joint 14 and lower contact 15 successively.
During work, high-pressure fluid is passed into from the circumferential through-hole of piston bush 2, the gap of fluid between piston 3, glue tube base 4, central tube 5, then flow into the gap between jump ring 11 and urceolus 10 through the circumferential through-hole of neck bush 9, finally by urceolus 10 circumference through-flow go out; The high-pressure spray passed into is known from experience promotion glue tube base 4 and is moved downward, and promote neck bush 9 and jump ring 11 moves downward, most Zhongdao jump ring 11 is stuck with urceolus 10, tubing pressure can be bled off, due to spacer ring 8 and urceolus 10 motionless, therefore packing element 6 by compression-expansion, can prop up pit shaft outer wall, plays the effect of packing.During deblocking, upper lifting pipe post, allows jump ring 11 be separated with urceolus 10, realizes deblocking.
