Wherein, the passage of bottom cycle assembly 1 be used for by brine replace mud discharge, while launch thereon setting ball into
Row closure, and then suppress setting tail tube hanging packer 3 and each open hole packer 4.
Open hole packer 4 realizes the reconstruction scope, and horizontal segment reservoir can be separated during downhole pipeline at the scene, setting
After realize multistage transformation packing effect, reduce the secondary injury produced to reservoir using well cementing of cement.
Ball seat fixing device 5 pumps perforation connection with the tripping in of tool pipe string and makees and solvable ball seat in place, during pressing crack construction, shoots away
Solvable ball sealing to be thrown behind hole to block up, and can carry out fracturing reform step by step to interval of interest, solvable ball seat and solvable ball can dissolve after pressure, because
This can directly carry out discharge opeing and ask production, without boring abrading-ball seat.
End open sliding sleeve 2 can be to avoid a secondary aperture be penetrated, i.e., on the compartmented that first segment has end open sliding sleeve 2 less
Without perforation.
Wherein, bottom cycle assembly 1, end open sliding sleeve 2, open hole packer 4, ball seat are located in device 5 and tail tube hanging
It is connected with each other between packer 3 by the casing 6 of multiple screwed connections.That is, pass through between the adjacent instrument of each two
The casing 6 of multiple screwed connections is connected with each other.Multiple screwed connections are also equipped between tail tube hanging packer 3 and well head
Casing 6.The internal diameter of each casing 6 is 4 inches -5 inches, is preferably 4.5 inches.
The quantity that the quantity of open hole packer 4 is located in device 5 with ball seat is identical, the two, which is corresponded, is set.In this implementation
In example, the quantity that quantity and the ball seat of open hole packer 4 are located in device 5 is respectively multiple and quantity is identical, open hole packer 4 with
Ball seat is located in device 5 and is alternately arranged, and it is along end open sliding sleeve 2 to tail pipe that open hole packer 4 and ball seat, which are located in device 5,
The direction of hanging packer 3 is alternately arranged successively.In other embodiments, the quantity of open hole packer 4 and ball seat are located in device 5
Quantity can also be respectively one, similarly, open hole packer 4 and ball seat be located in device 5 be along end open sliding sleeve 2 to
The direction of tail tube hanging packer 3 is set gradually.
The fracturing process of said modules infinite stages full-bore includes：
S1, the cementing concrete for striking off with pipeline scraper internal surface of sleeve pipe；
S2, with drill bit drill through Open-Hole Section, and well is ganged up with simulation pipe；
S3, using casing connection bottom cycle assembly 1, end open sliding sleeve 2, open hole packer 4, ball seat be located in device 5
With tail tube hanging packer 3；
S4, under be drilled into the setting depth of tail tube hanging packer 3；
S5, circulate Open-Hole Section and replace mud, and is discharged from bottom cycle assembly 1；
S6, throw setting ball, for blocking bottom cycle assembly 1；
S7, suppress setting tail tube hanging packer 3；
S8, each setting open hole packer 4；
S9, above carry or transfer the slips that tubing string tests envelope tail tube hanging packer 3；
S10, annular space suppress the packing element for testing envelope tail tube hanging packer 3；
S11,3 setting instrument of tail tube hanging packer are slipped out of the hand；
S12, trip-out；
S13, tripping in pressure break tieback string, tieback plug pressure testing；
S14, installation well head；
S15, pressing crack construction；
Opening end open sliding sleeve 2 is suppressed in S16, casing 6 to construct；
S17, the quantity for being located according to ball seat device 5, repeat following process：Solvable ball seat to corresponding ball seat is pumped to be located in
Device 5, and cable transmission perforation device perforation is pumped, put into setting solvable stifled ball to solvable ball seat and construct；
S18, open flow discharge opeing；
S19, ask production.
Above-mentioned steps S17 then needs repeat step it should be noted that when the quantity that ball seat is located in device 5 is multiple
S17, can just enter step S18；When the quantity that ball seat is located in device 5 is only one, then directly entered step from step S17
S18。
The utility model proposes component avoid well cementing of cement pollution stratum, cement sheath thickness and cause pressing crack construction after perforation
The problem of difficult；It also avoid needing for acid come handle perforation holes and near-earth reservoir to cause acid solution to return discharge pit shaft post processing tired
It is difficult to and the problem of processing cost is high.The utility model proposes component abrading-ball seat need not be bored after construction, directly carry out
Production, reduces the construction risk brought in direct operation link and construction, shortens construction period.
It is new using this practicality since well cementing of cement pollution near wellbore stratum causes pressure break height of constructing in pressing crack construction
The component of type can improve construction success rate, reduce to formation contaminant, increase nearly well and lose heart area, beneficial to gas output, at the same time
Full-bore after pressure, beneficial to secondary transformation and water pumping gas production operation, improves recovery ratio；Using solvable ball seat and solvable ball, Ke Yizhi
Tap into row discharge opeing and ask production, without boring abrading-ball seat, reduce direct operation link with pressure, reduce construction risk, shorten construction period, drop
Low on-site personnel labor intensity, reduces construction cost.
It should be appreciated that it will be understood by those skilled in the art that can according to the above description be improved or converted, but this
A little improvement or conversion should all belong within the protection domain of the appended claims for the utility model.
