Isipakishi seSeti yoMbane woMbane
Ipakhi yombane esetyenzisiweyo yeyona packer isetyenziswa ngokuqhelekileyo. Inokufakwa ngokukhawuleza nangokuchanekileyo kubunzulu obufunekayo bomthombo. Emva kokumisela ipakethe, unokwenza i-RIH kunye nendibano yetywina yemveliso kunye netyhubhu yemveliso. Nje ukuba idibaniso yetywina itywine kwipaki, vula umtya wetyhubhu kwaye uqhubeke nemisebenzi yokugqiba.
Hydraulic Seti Packer
Kukho iimeko apho kunqweneleka ukuqhuba isipakishi seseti yombane, nangona kunjalo, iimfuno zomthonyama zinokuthintela ukusebenzisa indlela enjalo. Isixhobo sokuseta i-hydraulic sisenokusetyenziswa ukulungiselela ukusebenza kweseti yombane yombane. ithatha nje indawo yesixhobo sokucwangcisa i-wireline xa iimeko ziyalela. Unokwenza lula i-M/U & RIH ngepaki exhotyiswe ngesixhobo sokuseta amanzi kwimibhobho yokomba. Nje ukuba ubunzulu, yiphose ibhola ngomtya kwisihlalo sayo sebhola. ngokusebenzisa impompo yodaka, uxinzelelo lusebenza isixhobo sokumisela esiya kumisa umpakishi. Emva koko i-POOH kunye nesixhobo sokumisela i-hydraulic kunye nomtya wokusebenza kunye nezitywina zemveliso kunye netyhubhu ziqhutywa ukugqibezela iqula.
Eminye imiqathango enokufuna ukusetyenziswa kwesixhobo sokuseta ulwelo olumanzi zezi:
•Ukuba kukho ipakethi esezantsi ebekwe ngaphambili endaweni, izitywini zompakisho obalekayo ziya kufunwa ukuba zityhalelwe kuloo paki kusetyenziswa ubunzima bomsebenzi.
•Ukuba ubunzima bompakishi kunye nezixhobo ezinxulumeneyo kunye nezixhobo zingaphezulu kweyona nto inokusingatha intambo yombane.
•Ukuba ubunzima bodaka okanye i-viscosity iphezulu kwaye umpakishi akakwazi ukuwa kunye nobunzima bakhe ukuba uqhutywe kwi-wireline yombane. Ubunzima bombhobho bunokufunwa ukutyhala umpakishi ezantsi.
•Njengoko i-angle yokuthambekela isiya iba nkulu, inqaku lifikelelwa apho umpakishi engasayi kuphinda awe phantsi equleni kunye nobunzima bakhe, okuya kufuna ukusebenzisa umtya wokusebenza.
Mechanical Seti Packer
Iipakethi ezinokubuyiselwa ngoomatshini ziyilelwe ukuba ziqhutywe kwaye zisetwe kwi-tubhing, zikhutshwe, zihanjiswe, kwaye zibekwe kwakhona ngaphandle kokukhubekisa ityhubhu. Zinokufunyanwa, zilungiswe (ukuba kuyimfuneko), kwaye zisetyenziswe kwakhona kwaye kwakhona. Aba paki ngabapakishi "UHAMBO OLUNYE".
Kukho iintlobo ezininzi zeepakethi ezinokubuyiselwa ngoomatshini ngokusekelwe kwintshukumo yetyhubhu efunekayo ukuseta ipakethe.
Uhlobo lwangaphakathi lwe-latch ye-mechanical retrievable packers yenzelwe ukuba iqhutywe kwi-tubing kwaye ibekwe ngokujikeleza ipakethe (malunga ne-1/4 yesandla sokunene) kwaye emva koko ubeke ubunzima kwi-packer. Emva kokuseta, ubunzima be-tubing bunokushiywa kwi-packer okanye buhlukaniswe ngaphandle koxinzelelo okanye ukungathathi hlangothi. Ukukhutshwa kufezekiswa ngobunzima betyhubhu phantsi kunye nokujikeleza ngasekunene.
Usetyenziso lwale paki ziquka:
•Uvavanyo kunye nokuvuselela indawo
•Imveliso
•I-ankile yetyhubhu
I-mechanical hook wall packer iyilwe ngezinto ezininzi ezifana ne-latch packer ekhankanywe ngaphambili. Nangona kunjalo, uxinzelelo alunakutsalwa kulo mpakisho. Iyaqhutywa kwaye ibekwe kwityhubhu, ikhululwe, ishukunyiswe, kwaye imiswe kwakhona ngaphandle kokukhubeka (ukukhubeka kombhobho) kwityhubhu. Zinokufunyanwa, zilungiswe (ukuba kuyimfuneko), kwaye zisetyenziswe ngokuphindaphindiweyo.
Le pakisha iqhele ukusetyenziselwa:
•Imithombo apho uxinzelelo oluphezulu olwahlukileyo lulindelwe ukusuka phezulu nangaphantsi kompakishi.
•Imveliso
•I-Acidizing- i-hydrofracking, uvavanyo, ukuswabhuka, kunye nolunye uxinzelelo oluphezulu lokuvuselela nokusebenza kwemveliso.
Hydrostatic Seti Packers
I-hydrostatic set packer iqukethe i-MHR eqhelekileyo okanye i-AHC esisigxina yokupakisha kunye nemodyuli yokumisela i-hydrostatic. Umpakishi usetwe ngaphandle kongenelelo lomthombo (okt akukho ziplagi okanye ezinye izixhobo ezifunekayo) kusetyenziswa uxinzelelo olukhoyo lwe-hydrostatic kunye noxinzelelo olusebenzayo lomphezulu. Umpakishi unento yokumisela i-contingency setting evumela ukuba ibekwe ngokufaka iplagi ngaphantsi kompakishi kwaye uyibeke ngokucinezela umtya we-tubing.
Izibonelelo:
•Yehlisa iindleko zokumisela umpakishi
•Ukunciphisa ixesha lokutya
•Isebenzisa uxinzelelo lwe-hydrostatic olukhoyo
•Yehlisa imingcipheko yongenelelo lwe-wellbore ukuseta okanye ukubuyisa iplagi yokuseta ipaki
Ingaba isebenza kanjani?
Imodyuli ye-hydrostatic, equlethe igumbi le-atmospheric, ihlanganiswe kwi-sub sub of packer. Iidiski eziqhekezayo zibandakanyiwe kuyilo lwemodyuli. Ekusetyenzisweni koxinzelelo kumphezulu kwiqula, iidiski ziyaphuka, ziveze i-hydrostatic setting piston kwi-wellbore hydrostatic pressure. Ukwahlukana koxinzelelo phakathi kwegumbi le-atmospheric kunye ne-wellbore hydrostatic inika amandla okumisela okuyimfuneko ukuseta ipakethe.
Inokusetyenziswa phi?
I-Hydrostatic set packers ingasetyenziswa kuphela phambi kokugqobhoza i-casing yemveliso okanye kwiqula apho i-casing kunye ne-tubing string inokunyanzeliswa ukuya kwixabiso elimiselweyo.
Okwangoku, uxinzelelo olupheleleyo kwi-packer kufuneka lube phakathi kwe-4,000 kunye ne-7,500 psi. Uxinzelelo olupheleleyo luchazwa njengoxinzelelo lwe-hydrostatic kwi-packer kunye noxinzelelo olufakwe kumphezulu. Uxinzelelo olufakwe kumphezulu lunconywa ukuba lube yi-25% yoxinzelelo lwe-hydrostatic kwi-packer. I-4,000 ye-psi encinci iqinisekisa isethi egcweleyo. Ubuninzi be-7,500 psi buqinisekisa ukuba nawuphi na umthwalo wokuwa owenziwe kwimodyuli yokumisela i-hydrostatic ngoxinzelelo olupheleleyo alubopheli imodyuli kwaye ngaloo ndlela luvimbela ukusetwa kompakishi. Kwiimeko ze-wellbore ezikufutshane nale mida, nceda uqhagamshelane noMcebisi wehlabathi ukuze ubone ukuba le teknoloji kufuneka isetyenziswe ekugqityweni.
