Kwicandelo lokugrumba umngxuma ongaphantsi komhlaba kunye nemisebenzi yokugqiba,iiplagikwayeabapakishiziintlobo ezimbini ezisisiseko zezixhobo ezenzelwe ukwahlulwa kweendawo ngaphakathi kwi-wellbore. Nangona zabelana ngomsebenzi oyintloko, usetyenziso lwazo oluthile, uyilo, kunye neendlela zazo zizenza zahluke kakhulu.
I. Ukufana: Isiseko Esifanayo
Zombini iiplagi kunye neepakethi zisebenza injongo efanayo esisiseko kwaye zisebenza ngomgaqo ofanayo osisiseko.
Umsebenzi oPhambili: Ukuzahlula kwiNdawo
Injongo ephambili yezi zixhobo zombini kukudala umqobo oqinileyo, oqinileyo ngaphakathi kwe-wellbor (ikheyisi okanye ityhubhu). Oku kwahlula iindawo ezahlukeneyo okanye iindawo ezahlukeneyo, kuthintela ukuhamba okungafunekiyo kolwelo (njengeoyile, igesi, okanye amanzi) phakathi kwazo.
Indlela Yokuvala Isitshixo: I-Element
Zombini ezi zixhobo zisebenzisa icandelo elinokwandiswa, elibizwa ngokuba yi-into yokutywinaLe nto yinxalenye ebalulekileyo edala isitywino ngokwasemzimbeni eludongeni lwangaphakathi lwebhokisi okanye ityhubhu.
Iindlela Zokuvula
Zombini iiplagi kunye neepakethi zingasetyenziswa kusetyenziswa iindlela ezifanayo zokwandisa into yokutywina:
Iseti yoomatshini:Ukusebenzisa amandla okucinezela ngokusebenzisa umtya wesixhobo okanye isixhobo sokuseta.
Iseti yeHydraulic:Ukusebenzisa uxinzelelo lwe-hydraulic oluvela kumphezulu okanye ngaphakathi kwi-wellbore.
Iseti yoMgca woMbane/woMbane:Isetyenziswe kwaye isetiwe kusetyenziswa i-wireline okanye iyunithi ye-e-line ukuze isebenze kakuhle.
II. Umahluko: Umahluko Ophambili
Umahluko ophambili usekwe kubunzima boyilo lwazo, ukusebenza kwazo, ukuhlala zihleli, kunye nokusetyenziswa kwazo ngokuthe ngqo.
| Uphawu | Iplagi yeBhulorho | Umpakishi |
| Umsebenzi oPhambili | Ukuthintela ukuhamba kwamanzi.Sisithintelo esenzelwe ukwahlukanisa indawo ethilengokupheleleyo, ngesiqhelo ukusuka ngezantsi. | Ukulawula Ukuhamba.Isebenza njengesiseko okanye iqonga lokwahlula iindawo ngelixa ivumela ukuhamba okulawulwayo kudlule embotsheni yayo. |
| Indlela Yokuhamba | IzithinteloAkukho manzi anokudlula kwisixhobo ngokwaso. | Ibonelela ngombhobho.Inembobo ecacileyo, evumela ulwelo ukuba luphume ngaphantsi luye phezulu, ngokufuthi ludlula kwiityhubhu eziqhotyoshelweyo okanye kwiintambo zokuvelisa. |
| Ubunzima boYilo | Ngokubanzilula ngakumbi. Isixhobo esiqinileyo sidla ngokugxila kuphela ekudaleni isitywina esithembekileyo. | KaninziubunzimaIbandakanya indlela eqinileyo yokutshixa, inkqubo yokutyibiliza yokubambelela, kunye ne-mandrel (ityhubhu ephakathi). |
| Inkqubo yokuNqamathela | Isenokuba neziqwenga ezilula okanye ixhomekeke kwisitywini. Yenzelwe ukumelana noxinzelelo oluvela kwelinye okanye kumacala omabini. | Inenkqubo yokutyibilika enobuchule (iikhowuni kunye neewedges) eziluma kwikhava ukuze zinike i-ankile eqinileyo, yoomatshini ngokuchasene namandla avela phezulu nangaphantsi. |
| Izicelo eziqhelekileyo | •Ukulahlwa kakuhle:Ukufaka ii-plug zones ngokusisigxina. •Ukukhuthaza:Ukwahlula indawo yokuqhekeza okanye ukufaka iasidi. •Ukulungiswa kwemithombo:Ukwahlula indawo evelisa amanzi. •Ukuzahlula Okwethutyana:Vavanya iiplagi, imisebenzi yeeplagi kunye nokulahla. | •Ukugqitywa:Isiseko sentambo yokuvelisa okanye yokufaka inaliti (umz., iProduction Packer). •Ukunyuswa kwegesi:Ukubonelela ngesitywino seemandrel zokuphakamisa igesi. •Imveliso yeMimandla emininzi:Ukwahlula iindawo ezininzi kwindawo enye. •Uvavanyo:Isetyenziswa kwizixhobo zovavanyo lwe-Drill Stem (DST). |
| Uhlala uhleli | IngayiIsigxina(iyakugqojozwa) okanyeInokufumaneka. | IngayiIsigxina(kufuneka igqojwe) okanyeInokufumaneka(ingasuswa kwaye ifunyanwe). |
III. Isishwankathelo kunye noHlalutyo
Kwimeko:
Cinga ngeIplagi yeBhulorhonjenge“Udonga Olungaphelelanga”okanye“I-Cork”kwipayipi. Umsebenzi wayo kuphela kukuvala indlela ngokupheleleyo. Idla ngokusetyenziselwa ukulungisa okanye umsebenzi wokwahlukanisa okwethutyana.
Cinga ngeUmpakishinjenge"I-Modular Junction"okanye"Icandelo leeMbhobho elinokuhlengahlengiswa kwakhona"Iyayivala i-annulus kodwa inombobo osebenzayo, ovumela ukuba ifakwe kwinkqubo enkulu (njengentambo yemveliso) ukuze kube lula ukuveliswa okanye ukufakwa okulawulwayo.
Ukukhetha phakathi kweplagi kunye nepacker kuxhomekeke ngokupheleleyo kwinjongo yokusebenza: ukuba imfuneko kukuvingca nje icandelo lomthombo, iplagi sisixhobo esifanelekileyo. Ukuba imfuneko kukwahlula indawo ngelixa usabonelela ngendlela yokuba ulwelo luhambe phezu komhlaba, ipacker sisisombululo esifunekayo.
