Pipe passes through packer, and upper port disposes pressure gauge 59, and connecting line 59-2 is reliably connected with master control borad 14, pressure probe 59-1 and envelope
Oil jacket annulus every device lower part is connected to.
As an implementation, referring to Fig. 6, the inlet opening on the interior middle pipe is substituted by liquid locking-valve: line being played to connect
Liquid locking-valve is arranged in headring week along axial inclined hole；The liquid locking-valve is by feed liquor piston 61, sealing ring 62, spring 63 and spring abutment 64
It constitutes.Specifically, sealing ring 62 is placed on feed liquor piston, so that feed liquor piston and eccentric orfice seal, spring base is fixed on feed liquor
The side of the separate lower contact of piston, spring is between spring base and feed liquor piston.
Working principle: setting: when O sealing ring 58 and the inclined hole 18-3 of third in motor switch on silk braid valve 57 contact, oil
Channel is covered to close；Pressure fluid enters Overline ring sky 61 through the radial hole 22-1 on interior middle pipe 22, respectively by inlet opening 25-1,
28-1 and 28-3 enters the intracavitary of seat 42 under upper fluid cylinder 23, lower fluid cylinder 27 and slips, and upper and lower fluid cylinder pushes close under hydraulic action
Sealing mechanism moves integrally, and a watt seat pin nail 36 is cut first under the action of upper tapered sleeve 33, the conical surface impetus of upper tapered sleeve 33
Lower external slips 40, which are extended radially out, to be contacted to form anchoring with internal surface of sleeve pipe, and pressure continues to increase, and rubber base pin 32 is cut, dynamic pressure ring
31, which move up the compression deformation of packing element 29, contacts to form sealing with internal surface of sleeve pipe, and lower fluid cylinder 27 pushes outer snap 34 to move forward, outer snap 34
Internal tooth engaged with the pawl of upper piston, pressure stabilizing certain time is completed setting when pressure rise is to design value, upper after pressure release to live
Plug is slightly moved back in packing element screen resilience, locks outer snap 34, anti-locking tooth；Due to the annular chamber 20b at 61 both ends of annular space
It is mutually balanced with deblocking chamber 43b, deblocking pin 19 is not subject to hydraulic load effect.
Annular space replaces liquid (or kill-job): motor switch is connected to instruction unpack i.e. oil jacket and is connected to, and puts into and can dissolve valve ball 60, under
Obtain support in the upper end of connector 50；Protection liquid (or well killing fluid) enter oil jacket annulus from switch, after motor switch be connected to finger
Enabling closing is that oil jacket is obstructed；It can dissolve valve ball 60 to dissolve at the appointed time, open lower passage.
Power supply and communication: well head is led in the upper end of upper steel pipe type cable 2, and lower steel pipe type cable 51 is connect with intelligence tool, realizes
Power supply and test data real-time Transmission.
Deblocking: above mentioning tool, is anchored sealing mechanism and casing-contact is motionless, upper piston drives outer snap 34 to move up, external lock
Spring 34 loses seat pin and cuts 35 coupling mechanism forces of set, and outer snap 34 is softened, and central tube 28 solves sealing mechanism and anchoring sealing mechanism generates
Relative displacement, after deblocking pin 19 is cut, solution sealing mechanism is integrally moved up, and closing piece 46 fell into the reducing slot of the end of a thread 47
In 47-1, seat 42 loses support under slips, under the screen resilience of packing element 29 and the frictional force effect with casing generation, anchoring sealing
Mechanism entirety downlink, external slips 40 recycle, and realize deblocking.
Working example: two-stage two-segment separate injection tubing string, by oil pipe+present invention+intelligence distributor+packer+intelligence distributor+
Oil pipe+silk plug etc. is constituted, and in oil pipe connection successively lower going-into-well, upper 2 upper end zero defect of steel pipe type cable connects out well head and ground
Control system connection, lower steel pipe type cable 51 are connect with other intelligence tools, keep power supply and communication normal.It is setting: to bristle with anger on ground
It enables, the oil jacket channel of electric-controlled switch is in close state, and the valve of upper and lower intelligence distributor is closed, present invention when pressurization in oil pipe
And packer completion is setting.Oil jacket annulus is replaced into protection liquid: electric-controlled switch is connected to open command, and oil jacket channel is in open shape
State, throwing from well head can dissolve valve ball 60, and injection protection liquid, opens wellhead casing pipe gate valve in oil pipe, replace into the bodies such as oil jacket annulus
Long-pending protection liquid, electric-controlled switch are connected to out code, and closed-in well muzzle sluice valve can dissolve valve ball 60 and periodically melt.Injection allocation: ground
Face sends instructions, and the valve of upper and lower intelligence distributor is opened, and infuses people CO simultaneously two layers2；Its injection rate, injection pressure and intelligence are matched
The every operating parameter for infusing device, is real-time transmitted to ground level control room by lower steel pipe type cable 51, upper steel pipe type cable 2.When operation: throwing
It can dissolve valve ball, first with well killing fluid for protection liquid is gone out, well killing fluid is full of pit shaft and indentation stratum after valve ball dissolution.Deblocking: it above mentions
Oil pipe, steel pipe type cable, the present invention and each intelligence tool are successively taken out in tubing string unfreezing of the present invention from well.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, the first, second equal words
It is only intended to the differentiation of title, is not the limitation to technical term, for those skilled in the art, the present invention can have
