Ukubeka iCasing Centralization

Ukusebenzisa ii-casing centralizers yindlela ebalulekileyo yokuphucula umgangatho wesamente.

Injongo yokufaka i-samente iphindwe kabini: okokuqala, ukwahlula ukujikeleza kwegazi okungazinzanga, okulahlekileyo, okanye ezinye iindawo ezinzima kunye ne-casing, ngaloo ndlela kubonelela ngokhuseleko lokuqhubeka nokugrumba ngokukhuselekileyo nangokugudileyo; okwesibini, ukwahlula ngokufanelekileyo iindawo ezahlukeneyo zeoyile negesi, ukuthintela ioyile negesi ekufudukeleni kumphezulu okanye ekufudukeleni phakathi kwezakhiwo, kunye nokubonelela ngomjelo wokuvelisa ioyile negesi.

Ngokusekelwe kwinjongo yokufaka isamente, iindlela zokuvavanya umgangatho wokufaka isamente zinokumiselwa. Umgangatho olungileyo wokufaka isamente ngokuyintloko uthetha ukuba isingxobo siphakathi kwi-wellboar, kwaye i-samente sheath ejikeleze isingxobo iyahlula ngokufanelekileyo isingxobo eludongeni lwe-wellboar kwaye yahlula iindlela ezahlukeneyo.

Nangona kunjalo, ii-wellbors ezigrunjiweyo azikho nkqo ngokupheleleyo kwaye ziya kuba namanqanaba ahlukeneyo okuphambuka. Ngenxa yokuphambuka kwe-wellbore, i-casing ayiyi kuba phakathi kwi-wellbore, nto leyo ebangela ubude obahlukeneyo kunye namanqanaba okunxibelelana nodonga lwe-wellbore. Oku kudala iindawo ezahlukeneyo phakathi kwe-casing kunye nodonga lwe-wellbore. Apho indawo ivulekileyo inkulu, udaka lokuqala lususwa lula yi-samente slurry; ngokuchaseneyo, apho indawo incinci, ngenxa yokumelana nokuhamba kwamanzi okuphezulu, i-samente slurry kunzima ukuyisusa endaweni yodaka lokuqala, yenze oko kubizwa ngokuba yi-samente slurry channeling. Nje ukuba i-channeling ivele, iindawo zeoyile negesi azinakwahlulwa ngokufanelekileyo, kwaye ioyile negesi ziya kuhamba kwiindawo ezingena-samente sheath.

Ukusetyenziswa kwee-casing centralizers kukugcina i-casing iphakathi kangangoko kunokwenzeka ngexesha lokufaka isamente. Kwimithombo ekhokelayo okanye ephambukile kakhulu, ii-casing centralizers zibaluleke ngakumbi. Ukongeza ekuthinteleni ngempumelelo ukutsalwa kwesamente, ii-casing centralizers zikwanciphisa umngcipheko wokunamathela ngokuhlukileyo kwe-casing. Ngenxa yokuba i-centralizer igcina i-casing iphakathi, i-casing ayiphumli eludongeni olune-wellbore; nokuba kumaxesha angena amanzi, i-casing ayinakwenzeka ukuba ibambeke ngenxa yekeyiki yodaka eyenziwe luxinzelelo oluhlukeneyo. Ii-casing centralizers zikwanciphisa ukugoba kwe-casing kwi-wellbore (ingakumbi kwiindawo ezinobubanzi obukhulu), ngaloo ndlela kunciphisa ukuguguleka kwe-casing yi-drill strings okanye ezinye izixhobo ze-downhole ngexesha lemisebenzi yokubhola elandelayo, ngaloo ndlela ikhusela i-casing. Ngenxa yenkxaso enikezelwa zii-casing centralizers, intambo ye-casing ingashukunyiswa lula ngakumbi ngexesha lemisebenzi yokufaka isamente.

Ngamafutshane, ukusetyenziswa kwee-casing centralizers yindlela elula, esebenzayo, nebalulekileyo yokuphucula umgangatho wesamente.
