Indlela yokukhetha iPacker?

Kakuhle iimeko.

● Uxinzelelo lweWell kufuneka luthathelwe ingqalelo njengoko ukhetho lwabapakishi kufuneka lwenziwe ngesakhono soxinzelelo esifanelekileyo sequla. Kuyimfuneko ukwazi ukuba ukuhlukana koxinzelelo kuya kuvela phezulu okanye ngaphantsi kompakishi kwaye ukuba ukuhlukana kuya kutshintsha ukusuka kwelinye icala ukuya kwelinye ngexesha lokuphila komthombo. Abanye abapakisheli bokugqiba baya kumelana noxinzelelo oluncinci ukusuka kwelinye icala.

● Utshintsho loxinzelelo lukwangumba wokunyakaza kwetyhubhu (i-elongation or contraction). Iqondo lobushushu liqwalaselwe kuba abanye abapakishi baya kwenza kumaqondo obushushu aphezulu kunabanye. Izipakishi ezinokubuyiswa kufuneka zithintelwe kumaqondo obushushu angama-300oF aphezulu. Iikhompawundi zokutywina ezisetyenziswa kwiiyunithi zokutywina zabapakisheli abasisigxina okanye i-packer bore receptacle ziyakukhethelwa ukusebenza kakuhle kumgangatho wobushushu obunikiweyo.

● Izinto ezitshabalalisayo kulwelo lwequla kufuneka ziqwalaselwe. Ngesiqhelo, abapakishi abanokubuyiswa abenzi kakuhle kumaqula anoxinzelelo oluphezulu lwe-H2S. Amaxesha amaninzi, ii-alloys ezisetyenziselwa ukwenziwa kompakishi kufuneka zikhethwe ukumelana neearhente ezitshabalalisayo eziya kuhlangana nazo.

● Ubude bexesha lokuvelisa yinto eqwalaselwayo ekukhetheni abapakishi. Ukuba ummandla kulindeleke ukuba uvelise iminyaka emininzi kungekho mfuneko yomsebenzi wokulungisa, kunokunqweneleka ukusebenzisa ipakethe yohlobo olusisigxina okanye i-hydraulic set retrievable packer. Nangona kunjalo, ukuba kuqikelelwa ukuba umsebenzi wokulungisa kwiqula uya kuba yimfuneko kwixesha elifutshane, kunokuba lunqweneleka ngakumbi ukusebenzisa i-packer ye-mechanical set packer.

● Ukuba iqula liza kunyangwa nge-asidi okanye i-frac imathiriyeli okanye lifakwe kumazinga aphezulu kunye noxinzelelo ngenxa yaso nasiphi na isizathu, umpakisheli ofanelekileyo kufuneka akhethwe Ukusilela kwePacker kaninzi kwenzeka ngexesha lokunyanga imisebenzi. Ukucutheka kwetyhubhu kunokuba nzima kakhulu ngexesha lonyango. Ukufinyezwa kunokubangela ukuba abapakishi ababuyisekayo bakhululwe, okanye kunokubangela ukuba izinto zetywina ziphume kumbhobho wetywina kumpakishi osisigxina okanye umpakishi.

Ukuhambelana nezinye izixhobo zeDownhole.

● Amaxesha amaninzi abapakishi bakhethwa ngenxa yokuhambelana kwabo nezinye izixhobo. Ngokomzekelo, apho iinkqubo ze-hanger zisetyenziswa kunye neenkqubo zokhuseleko eziphantsi komhlaba ezilawulwa ngumphezulu, kuyinqweneleka ukusebenzisa i-hydraulic set packers. I-Hydraulic set packers ivumela umqhubi ukuba afake kwaye abeke inkqubo epheleleyo yokhuseleko kunye nomthi ngaphambi kokumisela abapakishi. Ulwelo lwe-Well lunokuthi emva koko lususwe kunye nolwelo olulula ngelixa iqula liphantsi kolawulo olupheleleyo. Abapakishi banokumiselwa emva kokugqitywa kokukhutshwa kwamanzi.

● Ukuba izixhobo ze-wireline ziza kunikwa inkonzo kwi-tubhing okanye nge-tubing perforating kufuneka kuphunyezwe, kuyanqweneleka ukusebenzisa abapakishi abangafuni ubunzima betyhubhu ukuzigcina zisethiwe. Imisebenzi yocingo ingagqitywa ngempumelelo ngakumbi ukuba i-tubhing igcinwa ngokuthe tye ngokuyimisa ngokungathathi hlangothi okanye kuxinzelelo. Oku kubaluleke ngakumbi kumaqula anzulu.

● Kwiimeko ezininzi, ukhetho lwabapakishi luyenziwa ukuze lusetyenziswe kunye neevalvu zokuphakamisa igesi ukugcina uxinzelelo olusuka kwindawo yokuvelisa kunye nokuthintela irhasi ekuvuthelweni ekupheleni kwetyhubhu.

● Ukuba umpakishi uza kusetyenziswa kunye neyunithi yokumpompa intonga, ngokuqhelekileyo kunqweneleka ukuba i-tubhing ifakwe kwi-tension. Ukhetho lokupakisha kufuneka lwenziwe ukuvumela oku.

Ukhetho loMthengi.

Kufuneka ithathelwe ingqalelo into yokuba ngamaxesha amaninzi, iintlobo ezininzi ezahlukeneyo zabapakishi zinokusetyenziswa ngempumelelo kufakelo olufanayo. Amaxesha amaninzi, umpakishi unokukhethwa ngumsebenzi ngenxa yokuba uye wafumana impumelelo entle ngokuyisebenzisa kwixesha elidlulileyo.

Ezoqoqosho.

Uqoqosho lunokuba ngumba ekukhetheni abapakishi. Kwezinye iimeko, umqhubi kufuneka agcwalise i-indlela eyongayo kwaye uya kukhetha ipakethe ngenxa yeendleko zayo eziphantsi.

Ukuseta Ukuchaneka.

Ukuba i-packer ibekwe ngumgca womqhubi wombane, kunokwenzeka ukubeka ipakethe kwi-casing ngokuchanekileyo kakhulu. Ngamanye amaxesha, amaxesha okuvelisa asondelene kakhulu, okwenza kube yimfuneko ukubeka ipakethe ngokuchanekileyo.

Ezi zingasentla yimiba yereferensi yokukhetha ipakethe. I-Vigor ineminyaka emininzi yamava kwishishini leoli kunye negesi kwaye izimisele ukutshala imali kwi-R & D ukuqinisekisa ukuba i-Vigor inokubonelela ngezona zisombululo eziphezulu kubathengi bethu. Iipakethi ezivela kwi-Vigor ziyilelwe kwaye ziveliswa ngokusebenzisa imigangatho ye-API 11D, kwaye isetyenziswe kwintsimi ekhaya nakwamanye amazwe kwaye baye bamkelwa ngazwinye ngabathengi. Ukuba unemibuzo malunga nokukhetha ipakethe efanelekileyo okanye ukuba unomdla kwezinye izixhobo zokugaya kunye nokugqiba kwishishini leoli kunye negesi, nceda unganqikazi ukudibanisa noVigor kwiimveliso ezisemgangathweni kunye neenkonzo.
