Lunjani uvavanyo lwesatifikethi se-V0-class bridge plug packer?

Kuphuhliso nokuveliswa kwemithombo yegesi yendalo, ulawulo lwemithombo kunye neemfuno ze-HSE zingqongqo ngakumbi kunezo zemithombo yemveliso yeoyile. Enye yezona zinto ziphambili apha kukusebenza kokuvalwa kwe-hermeticabapakishi—izinto ezisebenza njengezinto eziphambili zokutywina phakathi kwezixhobo zokugqiba umngxuma ongaphantsi komhlaba.

Ukuqwalasela impembelelo yezinto ezifana nokulayisha imitya enzima kunye nokuguquguquka kobushushu ngexesha lokuveliswa kwemithombo yegesi yendalo ekusebenzeni kokutywina kunye nokubambelela kwabapakishi, umgangatho we-ISO 14310 (olingana ne-API 11D1) uhlela iziqinisekiso zabapakishi ezenzelwe imithombo yegesi zibe ziiklasi ezi-3. Inqanaba le-V0, eliquka uvavanyo lwegesi ephakathi, ukulayisha i-axial, ukujikeleza kobushushu, kunye nemigangatho ekhethekileyo ye-zero-bubble, lolona nqanaba lokuqinisekiswa olunzima nolungqongqo phakathi kwazo.

Iimveliso eziqinisekisiweyo kwinqanaba le-V0 zisebenza njengokhuseleko lokuveliswa ngokukhuselekileyo kwemithombo yegesi yendalo kunye nokubonakalisa ngokupheleleyo ubuchule bobuchwephesha babavelisi bezixhobo ezingaphantsi komhlaba. Phakathi kweepakethi zangaphandle ezisandula ukuqaliswa kunyeiplagi yebhulorhoiimveliso, zonke zigxininisa uphawu lwe-V0 njengophawu oluphambili; nangona kunjalo, abavelisi basekhaya abakayithengisi ngokusesikweni imveliso yodidi olufanayo.

Ngaphaya koyilo lwemveliso olunengqiqo kunye nokuveliswa okuchanekileyo nokungqongqo, ukusekwa kweenkqubo zovavanyo lwelabhoratri kunye nezikhokelo zovavanyo kukwayinxalenye ebalulekileyo yeemveliso eziqinisekisiweyo zebanga le-V0. Inkqubo yovavanyo lokusebenza kwesatifikethi se-packer yebanga le-V0 isetyenziselwa ikakhulu uvavanyo lwesatifikethi sebanga le-V0 kunye ne-API ephantsi. Ivelisa imizobo yemvulophu yokusebenza elinganisiweyo yabapakishi, kwaye kunye neepakeji zamaxwebhu engxelo yovavanyo, yenza icandelo eliphambili elixhasayo lokufaka isicelo sesatifikethi sebanga le-V0 kwezi mveliso.

Ngoku makhe siqhelane nenkqubo yovavanyo lokusebenza kwesatifikethi se-packer seklasi ye-V0.

Uyilo lweZakhiwo

Olu lwakhiwo lwenkqubo luyilelwe isiqinisekiso sovavanyo lwebanga le-V0, kwaye lunokuxhasa iziqinisekiso zovavanyo zamanqanaba aphantsi (umz., V1-V3) ngaphantsi kwe-V0. Inkqubo yovavanyo ikakhulu iqulathe izinto eziquka izixhobo zovavanyo, iinkqubo zovavanyo lwe-hydraulic, iinkqubo zovavanyo lwe-pneumatic, iinkqubo zokufumanisa amaqamza, kunye neenkqubo zokujikeleza ubushushu. Jonga le theyibhile ilandelayo malunga nesakhiwo senkqubo kunye nezixhobo eziphambili zenkqubo nganye engaphantsi.

Kuzo zonke ezi nkqubo zingaphantsi zikhankanyiweyo apha ngasentla, kufuneka isixhobo sovavanyo esakhelwe injongo ethile ukuze sikwazi ukufaka, ukulungisa, kunye nokuseta isixhobo, ukuzalisekisa iimeko ezahlukeneyo zovavanyo, kunye nokuqinisekisa iziphumo zovavanyo.

Iiadaptha zemibhobho ezibekelwe kwangaphambili zokuvavanya zifakwe kwisixhobo, nto leyo evumela uqhagamshelo kwiipayipi zovavanyo ezifanelekileyo ngexesha lovavanyo. Esi sixhobo sixhasa uvavanyo loxinzelelo olufanelekileyo (lomoya/olumanzi) phantsi kweemeko zobushushu ezingqongileyo, eziphezulu, neziphantsi.

Iimfuno zoYilo lweNkqubo yeZixhobo

Kwinkqubo yezixhobo, kufuneka kongezwe umaleko owongezelelweyo we-casing ngaphandle kwe-test casing ukuze kujikeleziswe umbane ophakathi kwiimvavanyo zobushushu obuphezulu nobuphantsi. Oku kuqinisekisa ubushushu bovavanyo obuzinzileyo ngaphakathi kwe-casing kwaye kuphucula ukhuseleko. Indlela ye-piston elungeleleneyo ingayilwa ukulawula umthwalo we-axial wesixhobo sovavanyo ngokutshintsha nge-hydraulic. Iivalvu zokhuseleko mazifakwe kuzo zonke iipayipi zovavanyo ukuqinisekisa ukhuseleko lwenkqubo yovavanyo.

Kwiimvavanyo zegesi kunye novavanyo lokufumanisa amaqamza, izixhobo ezifana nezifumanisi zamaqamza, iivalvu zokunciphisa uxinzelelo kunye neevalvu zokhuseleko kufuneka zongezwe kumbhobho ukuqinisekisa ukhuseleko lwabasebenzi ngexesha lovavanyo. Ngexesha lokufumanisa amaqamza, kufuneka kongezwe ipompo ye-vacuum kumbhobho ukuze kugcinwe imeko ye-vacuum, nto leyo eqinisekisa ukuchaneka kokufunyanwa kwamaqamza.

Iinkqubo zoVavanyo loXinzelelo oluPhezulu kunye noBushushu obuPhezulu

1.Qhagamshela umbhobho wolawulo, sebenzisa uxinzelelo lokuseta olulinganisiweyo, uze usete ipakethi.

2.Qhagamshela iadaptha yombhobho wokujikeleza ubushushu kwipompo yeoyile eshushu, qala ukujikeleza, kwaye ufikelele kubushushu bovavanyo.

3.Qhagamshela ipompo ye-hydraulic kwi-adapter yepayipi ye-hydraulic/pneumatic, cinezela kancinci kancinci kuxinzelelo lovavanyo, yenza ukubamba uxinzelelo, kwaye ujonge ukuba imeko yokubamba uxinzelelo iyahlangabezana na neemfuno.

Iinkqubo zoVavanyo loXinzelelo oluPhezulu kunye noBushushu obuphantsi

Qhagamshela iadaptha yepayipi yokujikeleza ubushushu kwinkqubo yegesi ebandayo, qalisa ipompo yokujikeleza, kwaye ufikelele kubushushu bovavanyo; iinkqubo eziseleyo ziyafana nezingasentla.

Iinkqubo zokufaka isicelo sokulayisha

Emva kokufikelela kuxinzelelo lovavanyo olulinganisiweyo kunye nokugqiba ukuzinzisa uxinzelelo, faka uxinzelelo kwiindawo eziphezulu nezisezantsi ze-adaptha yepiston ukuze uyiguqule ibe yimithwalo ye-axial kwiindlela ezahlukeneyo.

Imvulophu yokusebenza

Emva kokugqiba zonke iimvavanyo ezimiselweyo, kwenziwa ingxelo yovavanyo, kwaye kwenziwa umzobo wemvulophu yokusebenza kwepacker ngokusekelwe kwiziphumo zovavanyo. Oku kulandelayo ngumzobo wesampulu yepacker enokutsalwa kwakhona esekwe ngamanzi enomlinganiselo woxinzelelo we-7500 psi kunye nokukhululwa kwe-shear ye-40,000-lb.
