1. Umgaqo-siseko wolwakhiwo
Iplagi yebhulorho yokucinezela uthuthu enokubuyiselwa iqulethe isitywino sesihlalo kunye nendlela ye-anchor, indlela yokutshixa nokuvula, iswitshi yesingxobo esityibilikayo kunye nendlela yokuthintela ukunamathela, i-intubation kunye nendlela yokusindisa.
Isixhobo sokuseta intambo okanye isixhobo sokuseta i-hydraulic pipe singasetyenziselwa ukuthumela iplagi yebhulorho kwindawo emiselweyo yokuseta nokulahlwa, emva koko sikhuphe isixhobo sokuseta kunye nokutya, sifake isixhobo sokufaka ityhubhu kwiplagi yebhulorho yokucinezela uthuthu enokubuyiselwa, kwaye senze umsebenzi wokucinezela uthuthu. Emva kokucinezela uthuthu, phakamisa ityhubhu yokufunxa kwaye uhlambe umthombo. Emva kokuseta kokuqala kwe-mortar, i-overshot ingathotywa ukuze kuphume iplagi yebhulorho.
2. Inkqubo yomsebenzi
1. Indlela yokuseta kunye nokusebenza kokuvula itywina iyafana nendlela yokuvala eqhelekileyo.
2.Emva kokuba iplagi yebhulorho yokucinezela uthuthu isetiwe, qhagamshela i-cannula yokucinezela uthuthu ezantsi kwentambo yetyhubhu uze uyithobe kwi-wellbore, uyifake kwi-mandrel yeplagi yebhulorho yokucinezela uthuthu yohlobo lokubuyisela, uze ucinezele ivalvu yesilayidi.
3.Tshintsha i-samente slurry ngelori yesamente ukuze kucudiswe uthuthu.
4. Emva kokuba uthuthu lucinezelwe, phakamisa ngoko nangoko umtya wepayipi, khupha umbhobho wokufaka ityhubhu ukuze uvale ivalvu yesilayidi, kwaye ngoko nangoko uhlambe umngxuma ukuze uhlambe i-mortar yesamente engaphezulu kwi-wellboar. Ngenxa yokuba ivalvu yesilayidi ivaliwe, i-slurry yesamente engaphandle kokwakheka okanye umbhobho ayinakubuyela kwi-wellboar, nto leyo eqinisekisa umgangatho we-cementation kunye nefuthe lokuxhuba kwe-slurry yesamente, ifinyeze ixesha lokuhlala kwe-slurry yesamente kwi-wellboar, kwaye inciphise umtya wepayipi yokuqinisa i-slurry yesamente.
5. Ukuba umaleko ongaphezulu usetyenzisiwe, iRetrievable Bridge Plug of Cement Squeeze isetyenziswa njenge-plug yebhulorho eqhelekileyo kwaye ingafakwa kwimveliso ngokuthe ngqo; ukuba umaleko ongezantsi umbiwe, intambo yokusindisa engatywinwanga ifakwa equleni ukuze kususwe i-plug yebhulorho. Emva kokuba i-plug yebhulorho ikhutshiwe, beka izihlangu zokusila phantsi equleni ukuze kugqojwe i-plug yesamente. Ekubeni kungekho zixhobo zesinyithi, ukubhoboza nokusila kulula.
3. Iimpawu zobugcisa
1. Indlela yokuseta eguquguqukayo: Iplagi yebhulorho ingathunyelwa kwisetingi ngesixhobo sokuseta uhlobo lwentambo okanye isixhobo sokuseta se-hydraulic, kwaye isixhobo sokuseta esifanelekileyo singakhethwa ngokweemeko ezithile zomthombo.
2. Ulawulo oluchanekileyo lokuseta: Amandla okuseta eplagi yebhulorho alawulwa yi-tension rod (ring), eqinisekisa ukuseta okukhuselekileyo nokuthembekileyo kweplagi yebhulorho. Kwangaxeshanye, iqinisekisa ukuba isixhobo sokuseta sinokuphakanyiswa ngokukhuselekileyo siphume kwi-wellbore phantsi kweemeko ezinzima.
3. Uyilo oluthembekileyo lokulwa nokuxinana: Inxalenye yokutyibilika isebenzisa isakhiwo sokutyibilika esakhelwe ngaphakathi, kwaye iplagi yebhulorho akulula ukuhlangabezana nokuxhathisa nokuxinana xa iphakanyiswa kwaye yehliswa kwishafti. Emva kokuseta, ukutyibilika kweplagi yebhulorho kunye netyhubhu yerabha zifakwa phakathi ngokuzenzekelayo, kwaye zingasetyenziswa ngokukhuselekileyo kwimigodi enayo nayiphi na imigxobhozo etyebileyo kunye nemisele ethe tye.
4. Indlela yokubambelela eyahlukileyo: Iplagi yebhulorho isebenzisa indibaniselwano enobuchule yezilayidi, iikhowuni zokutyibilika, kunye neesilinda zangaphandle zokutyibilika. Inamandla okuthwala uxinzelelo oluya kwicala elinye kwaye ingafakwa kwiikheyiji zamanqanaba ahlukeneyo.
5. Indlela yokuvula iplagi yebhulorho ekhuselekileyo: Ukuvula iplagi yebhulorho kwenziwa inyathelo ngenyathelo ngokulandelelana kwendlela yokutshixa, indlela yokuvala, kunye nendlela yokutyibilika. Nokuba uxinzelelo oluphezulu nolusezantsi lweplagi yebhulorho lulinganisiwe, amandla okuvula afunekayo mancinci kakhulu.
6. Kulula ukugrumba nokugawula iplagi yothuthu: emva kokusebenza kokucudisa uthuthu kweplagi yothuthu ephinda isetyenziswe, iplagi yothuthu ingatsalwa, kwaye kulula ukugrumba nokugawula iplagi yothuthu.
7. Zinendlela ethile yokubhoboza: iplagi yebhulorho inesakhiwo esincinci, isakhiwo esingaphezulu senziwe ngezinto ezinokubhoboza ngcono, kwaye indlela yokutshixa yangaphakathi iphezulu kwiplagi yebhulorho, nokuba iplagi yebhulorho ayinakudotywa ngenxa yezizathu ezingaqhelekanga, kusenokuba lula ukuyibhoboza.
