Detailed description of the invention
As shown in Figure 1, deepwater wells parallel double tube packer, including: top connection 1, hydraulic pressure washing pipe 2, upper slips cover 3, upper slips 4, upper cone 5, packing element 6, hydraulic pressure internal member 7, hydraulic sleeve 8, lock ring 9, lower cone 11, lower slips 12, lower slips cover 13, solution seal ring 14, auxiliary pipe 15, lower contact 16, shearing nut 17 and shear pin 18；Wherein:
In described top connection, 1 has two holes, threadeds with hydraulic pressure washing pipe 2, auxiliary pipe 15 respectively, and hydraulic pressure washing pipe 2 is provided with pressure transmission hole 10, and hydraulic pressure washing pipe 2 lower end is provided with annular groove；
Described upper slips cover 5 is nested on hydraulic pressure washing pipe 2 and auxiliary pipe 15, and threadeds with top connection 1；
Described upper cone 5 is provided with two through holes, and two through hole correspondences respectively are inserted in hydraulic pressure washing pipe 2 and auxiliary pipe 15；Upper slips 4 is located between upper cone 5 and upper slips cover 3；
As in figure 2 it is shown, packing element 6 is provided with two tubing string holes, two tubing string hole correspondences respectively are inserted in hydraulic pressure washing pipe 2 and auxiliary pipe 15；
Described lock ring 9 is internal is provided with saw-tooth thread, and lock ring 9 is threadeded with hydraulic pressure internal member 7, and the hydraulic sleeve internals 7 equipped with lock ring 9 are nested on hydraulic pressure washing pipe 2 and auxiliary pipe 15, and hydraulic sleeve 8 is nested in hydraulic sleeve internals 7.
Described lower cone 11 end face is provided with two through holes, and two through hole correspondences respectively are inserted on hydraulic pressure washing pipe 2 and auxiliary pipe 15；Lower slips 12 is placed in lower slips cover 13, and lower slips 12, lower slips cover 13 are nested on hydraulic pressure washing pipe 2 and auxiliary pipe 15 in the lump, and lower slips 12 is propped up by lower cone 11；
Described solution seal ring 14 is nested on hydraulic pressure washing pipe 2 in the groove arranged；
Described lower contact 16 is provided with two through holes, and two through hole correspondences respectively are inserted on hydraulic pressure washing pipe 2 and auxiliary pipe 15, and threaded with lower slips cover 13 in upper end.
Described shearing nut 17 is nested on hydraulic pressure washing pipe 2, threadeds with lower contact lower end, is shearing on nut 17 equipped with the shear pin 18 required for deblocking, can set the shear force of shear pin 18 according to deblocking power size.
As shown in Figure 2, deepwater wells parallel double tube packer uses and improves packing element structure, the structure of packing element 6 is directly to make a call to two tubing string holes on packing element, make two endowels can be each passed through tubing string hole, when setting, requisite space is little, it is possible to increase dual string diameter, when being more beneficial for deepwater wells exploitation, realize dual tubing oil recovery, the needs that many group bunchs of cables pass through simultaneously.
Deepwater wells parallel double tube packer uses dual-grip structure, can bear the power impact that lower tubular column is different on packer, oil pipe can be avoided to produce bending, adapt to working environment severe under deepwater wells.Shearing nut 17 and shear pin 18 are set in lower cone 11 lower end so that it is when deblocking, only need to put on joint 1 and can complete deblocking.Overall construction design is compact, sets and unseal conveniently, it is simple to operation.
When setting, suppressing in oil pipe, liquid is entered by pressure transmission hole 10, makes lock ring 9 and hydraulic sleeve internals 7 upward sliding, promotes packing element 6, and upper cone 5 moves upward, and makes upper slips 4 open and sets, and lock ring 9 is locked with hydraulic sleeve 8, and then packing element 6 sets and reaches to insulate purpose；The hydraulic pressure entered by pressure transmission mouth 10, makes hydraulic sleeve 8 slide downward simultaneously, promotes lower cone 11 to move downward, makes lower slips 12 open and reach to set purpose.
During deblocking, carry in oil pipe connection top connection 1, hydraulic pressure washing pipe 2 moves upwardly together, upper slips cover 3, upper cone 5, packing element 6, hydraulic pressure internal member 7, hydraulic sleeve 8, lower cone 11, lower slips cover 13, lower contact 16, shear nut 17 geo-stationary motionless, deblocking pin 18 is cut off under shearing the effect of nut 17 and hydraulic pressure washing pipe 2, shear nut 17, lower contact 16 and lower slips cover 13 to move down, lower slips 12 unseals, lower cone 11, hydraulic sleeve 8, hydraulic sleeve internals 7 move down together, packing element 6 unseals, upper cone 5 moves down, and upper slips 4 unseals.Solution seal ring 14 can be blocked each part of lower slips more than 12 and move down, and deblocking process completes.
