Working principle
The installation of minor diameter speed column as shown in figure 5, oil pipe 4 has been mounted to the flow string in casing 6 before being,
Minor diameter speed column 5 is sealed against being fixed in oil pipe 4 by hanging sealer 1, and the channel of circulation is reduced, well is improved
Fluid-carrying capability.The installation for hanging sealer includes feeding and removal process.
One, suspension sealer is sent into process
Suspension sealer of the invention is sent into process as shown in fig. 6, being divided into three processes: A) it is connect with suspension sealer；
B) pressurize setting procedure；C it) gives up process.
A) connect with suspension sealer: as shown in Figure 6, when running tool 2 is sent into, the lock tube 217 of running tool 2 is inserted
Enter to hang in the top connection 101 of sealer 1, closing piece 216 is ejected by the bulge loop 2151 of locking bar 215, and lock connects on suspension sealer 1
In first 101 stopping step 1011, tripping in is suspended in midair entirely through the coiled tubing that the top connection 201 with running tool 2 is connect
In well, until designated depth.
B) pressurize setting procedure: when starting setting, ground passes through running tool 2 to coiled tubing internal pressurization, liquid
201 inner hole of top connection enters running tool 2, is sealed in lower part by sealed steel ball 214 and locking bar 215.Therefore, pressure passes through center
The entrance of aperture 222 and each small piston chamber on pipe 204 and each section of piston rod, and push piston cylinder to underground moving, it can cut at this time
Disconnected shear pin 206(or more piston cylinder can be with relative motion in stroke range), and pushing cylinder 212 is pushed to act on suspension sealer
Pushing cylinder 102, as shown in Figure 6 (b).At this point, pushing cylinder 102 cuts shear pin 103, start to push center tap 105, and squeeze packing element
109,110 spreading, and squeezed out slips 114 by the seat of honour 112, so that slips 114 is firmly grasped 4 inner wall of oil pipe, realizes suspension sealer 1
Setting (referring to Fig. 1, Fig. 5).
C) give up process: be forced into it is setting after the completion of pressure continue to increase, shear sleeve 218, shear screw 219, shearing ring
The shearing force of the shearing positioning device of 220 compositions cannot block the thrust that pressure is formed to sealed steel ball 214 and locking bar 215 again
When, shear screw 219 is cut, and pressure is pushed forward sealed steel ball 214, locking bar 215, shearing ring 220 to top, at this time closing piece 216
It drops into outside the bulge loop 2151 of locking bar 215, as shown in Figure 6 (c), running tool 2 is given up with suspension sealer 1 at this time.
Two, sealer removal process is hung
Suspension sealer removal process of the invention is as shown in fig. 7, the recycling insertion of tool 3 is hung in sealer 1, benefit
First catch on the gear on suspension sealer 1 from down in the unlocked position B of suspension sealer 1 with the claw 316 of 3 lower end of recycling tool
Ring 123 upwards mentions cut shear pin 122, at this time hang sealer 1 claw 119 and baffle ring 123 be detached from, therefore claw 119 with
Threaded engagement structure 126 between lower contact 124 is released, and lower seat 117 moves downwardly together with lower contact 124, slips 114
And packing element 109,110 resets, and makes to hang sealer 1 from the release of oil pipe 4 (referring to Fig. 1, Fig. 5), recycling tool 3 is salvaging position A
Place's claw 310 catches suspension sealer 1, mentions coiled tubing upwards for the tubing string 5 for hanging sealer 1 and connection and is recovered to ground
Face.
