Abstract
The utility model relates to a hanging packer for a horizontal well, which comprises a retrievable tool part and a sealed hanging part, wherein the retrievable tool part is connected with the sealed hanging part and comprises an upper joint, a piston, a hydraulic cylinder, a retrievable tool ball seat, a retrievable tool pawl spring and a supporting sleeve; the sealed hanging part comprises a locking ring, a high-temperature sealing piece, a cone, bidirectional slips, a slips seat, a central pipe, a seal-releasing sliding sleeve and a lower joint. For the hanging packer of the horizontal well, double hydraulic cylinders are adopted, the thrust is strong, the seat seal is good in sealing, the hanging is firm, and double insurance retrievable tools are adopted, thus being reliable and effective, being capable of bearing greater tubular column load, and being capable of bearing greater lifting and lowering tonnage when meeting resistance; and the rear latus rectum of the retrievable tool is phi 160, the application scope is wide, the high-temperature sealing piece can work for a long time at the temperature of 350 DEG C and high pressure, and also can be used for a long time at normal temperature.
Description
Technical field
The utility model relates to a kind of horizontal well hanging packer.
Background technology
The hanging packer sealing performance that present existing horizontal well is used is bad, and it is firm inadequately to hang, and only can bear a certain amount of load, can not satisfy the demands, and can only use at normal temperatures usually.
The utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of horizontal well hanging packer.
A kind of horizontal well hanging packer; Wherein, Hanging packer partly is made up of the part of giving up, sealed suspension; The part of giving up partly is connected with sealed suspension, and the part of giving up comprises top connection, piston, fluid cylinder, the ball seat of giving up, the pawl spring of giving up, splicing sleeve, and sealed suspension partly comprises binding ring, elevated-temperature seal part, cone, bi-directional slip, slip spider, central tube, deblocking sliding sleeve, lower contact.
Its beneficial effect comprises:
1. adopt biliquid cylinder thrust big, seat envelope good seal, it is firm to hang, and dual fail-safe is given up, and is effectively reliable.
2. bigger tubing string load can be born, the bigger tonnage that raises and decentralizes can be born when being hampered.
3. latus rectum Φ 160 applied ranges after giving up.
4. adopt the elevated-temperature seal part also can use for a long time at normal temperatures in long-term work under 350 ℃ and the high pressure.
Description of drawings
Fig. 1 is the structural representation of horizontal well hanging packer.
Fig. 2 is the stereogram of horizontal well hanging packer.
Wherein, The Reference numeral implication is: 1---part, 2 of giving up---sealed suspension part, 3---top connection, 4---piston, 5---fluid cylinder, 6---ball seat of giving up, 7---pawl spring of giving up, 8---splicing sleeve, 9---binding ring, 10---elevated-temperature seal part, 11---cone, 12---bi-directional slip, 13---slip spider, 14---central tube, 15---deblocking sliding sleeve, 16---lower contacts.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described further.
See Fig. 1, the horizontal well hanging packer mainly partly is made up of the part of giving up, sealed suspension, and the part of giving up partly is connected with sealed suspension, and the part of giving up is made up of top connection, piston, fluid cylinder, the ball seat of giving up, the pawl spring of giving up, splicing sleeve etc.The sealed suspension part is made up of binding ring, elevated-temperature seal part, cone, bi-directional slip, slip spider, central tube, deblocking sliding sleeve, lower contact etc.
Hanger adopts waterpower seat envelope, on carry deblocking.The suspension of seat envelope, the structure of giving up and accomplishing simultaneously.Tubing string is arrived design attitude down; Drop into steel ball, (or with the direct turn on pump of plug) builds the pressure with cementing truck, and the piston of the part of when pressure reaches 9～10MPa, giving up begins to promote binding ring, elevated-temperature seal part, cone and bi-directional slip; Pressure continues to be promoted to 18～22MPa elevated-temperature seal part and compresses; Bi-directional slip blocks internal surface of sleeve pipe, binding ring locking, and the suspension of seat envelope is accomplished.It is descending that the ball seat of when pressure reaches 18～22MPa, giving up simultaneously promotes splicing sleeve, breaks away from the pawl spring of giving up, and the pawl spring of giving up loses supporting to begin to shrink, and just can from central tube, pull out the suspension of upper lifting pipe column base envelope, the completion of giving up.As above carrying tubing string can not can just change 20～25 weeks of back-off by deblocking, and the pawl spring of giving up just can be pulled out from central tube, the completion of giving up.
Its technical data is:
The utility model can be used for managing interior sand control pipe hanger, or use with other packer can oil production by layer, layered gas-injection, accent layer, realized pump technique.Can exempt from when it also can be used as high temperature bridge plugging lower floor to annotate ash, when afterbody connects 7 〞 sleeve pipes, can form a little artificial bottom of a well, also can be used for the shutoff interlayer.
