Iplagi yebhulorho enyibilikayo yenziwe ngemathiriyeli entsha, esetyenziswa njengesixhobo sokutywina sethutyana sequla lokutywina lokuqhekeka komthombo othe tye kunye nohlengahlengiso.
Iplagi yebhulorho enyibilikayo yenziwe ikakhulu ngamalungu ama-3: umzimba weplagi yebhulorho, indlela yokubambelela kunye nezitywina. Umzimba weplagi yebhulorho yenziwe ngezinto ezinyibilikayo ezinokuqina okuphezulu, kubandakanya ityhubhu ephakathi, ikhowuni, umsesane wokukhusela kunye namalungu. I-anchoring mechanism yenziwe ngezinto ezichithwayo njengomthwali, kwaye umphezulu uphathwa nge-alloy powder, i-alloy particles okanye i-ceramic particles. Iimpawu ziyirabha okanye iplastiki echithwayo.
I-1.Iinxalenye zeeplagi zebhulorho ezichithwayo
Iiplagi zebhulorho ezinyibilikayo zenziwe ngamandla aphezulu e-magnesium-aluminiyam ialloy okanye i-polymer material processing. I-Magnesium-aluminium alloy ikakhulu yenziwe nge-magnesium, kunye ne-low density (malunga ne-1.8 ~ 2.0g / cm³), kwaye kwangaxeshanye, umsebenzi wayo weekhemikhali uphezulu, ngoko kulula ukuchithwa kwindawo enomswakama.
Izinga lokuchithwa kwe-magnesium-aluminiyam i-alloy inxulumene ikakhulu nobushushu bolwelo kunye ne-Cl-concentration, iqondo lokushisa eliphezulu, ngokukhawuleza ukuchithwa; Ukuphakama kwe-Cl-concentration, ngokukhawuleza ifilimu ye-passivation kwi-alloy surface iyonakalisa, i-conductivity engcono yolwelo, ngokukhawuleza isantya sokuchithwa.
2.Dissovable ibhulorho plug indlela yokubambelela
Disovable ibhulorho iplagi i-anchoring ithayile yahlukile kwithayile yentsimbi etyhidiweyo kunye nethayile edibeneyo, ukongeza kwimfuno yokubonelela nge-anchoring force ethembekileyo kunye ne-cylinder yokutshixa amandla, kodwa kufuneka ibe nokusebenza kakuhle kokuchithwa kunye nokukwazi ukubuyela ekukhupheni.
3.Dissolvable Bridge Plug Seat Ixabiso Release
I-Baker 20 # isixhobo sokuhlala se-hydraulic iya kuba yiplagi yebhulorho enokuchithwa ehleli kwisixhobo se-casing, inkqubo yokuvavanya iplagi yebhulorho kunye nesixhobo sokuhlala ihambelana kakuhle, iplagi yebhulorho ihleli ngempumelelo kwaye ilahlekile ngesandla, ukulahleka koxinzelelo lwesandla lwe-12.3MPa. (ilahleko elinganayo yamandla esandla emalunga ne-155kN) ehleli igophe lesandla njengoko kubonisiwe kulo mfanekiso.
4.Uxinzelelo lokutywinwa kokusebenza kweplagi yebhulorho enokuchithwa
Ukuze kuqinisekiswe ukusebenza koxinzelelo lobushushu obuphezulu bokutywinwa kweplagi yebhulorho enokuchithwa, umsebenzi wecasing wafakwa kwisixhobo sokulinga lobushushu obuphezulu kwaye wafudunyezwa kwi-93°C. Emva kokuba iqondo lobushushu lizinzile, uxinzelelo lwanyuswa kancinci ukuya kuma-70 MPa. Uxinzelelo lwazinziswa kwiiyure ezingama-24 kwaye emva koko lwagcinwa imizuzu eyi-15. Kukho ukuhla koxinzelelo olucacileyo kwaye ijika lovavanyo loxinzelelo luboniswa kumzobo. Iziphumo zovavanyo zibonisa ukuba ukusebenza kokutywinwa koxinzelelo lweplagi yebhulorho kunokuhlangabezana neemfuno zokwakhiwa kwefracturing kwisiza.
5.Ixesha lokusebenza kweplagi yebhulorho enokuchithwa
Umda wexesha lokusebenza lithuba lexesha ukusuka xa iplagi yebhulorho ifakwe equleni ukuya kwifracturing. Ngokwemodeli ekhoyo yokwakhiwa kwegesi ye-shale, umda wexesha lokusebenza kwiplagi yebhulorho echithwayo ziiyure ezingama-24, ezinokuhlangabezana neemfuno zokwakhiwa kwendawo yamaqula erhasi ye-shale, oko kukuthi, ukususela kwixesha apho iplagi yebhulorho echithwayo ifakiwe. equleni Ukuqala kwiyure, ulwakhiwo lwefracturing lunokwenziwa kwiiyure ezingama-24. Naluphi na uvavanyo lokusebenza kwiiplagi zebhulorho ezichithwayo zinokuqhutywa ngokubhekiselele kumda wexesha lokusebenza iiyure ezingama-24.
