Ukuthuthukisa Ukuzinza Kwe-Casing Nge-Slip-On Welded Solid Solid Body Rigid Centralizers

Uma kuziwa ekuqinisekiseni ukwehla okushelelayo nokuzinzile kwe-casing emithonjeni echezukile nevundlile, ukugqagqana komugqa, namajoyinti ezicathulo, ukukhethwa kwezinto ezimaphakathi kudlala indima ebalulekile. Phakathi kwezinketho ezahlukene ezitholakalayo, umzimba oqinile oshibilikisiweama-centralizers aqinilezigqame ngamandla azo asekelayo aphezulu namandla okuqala aphansi, okwenza i-casing yehle kahle kuyilapho igcina izinga eliphezulu lokuzinza.

Leziama-centralizersziza ngosayizi ohlukahlukene, ukusuka ku-4-1/2" kuye ku-20", futhi zingahle zenziwe ngokwezifiso ukuze zihlangabezane nezidingo ezithile. Idizayini yabo ye-spiral vane iphinde yehlise amandla okudonsa, ibenze ibe inketho efanelekile kuzo zombili izinhlelo zokusebenza ezinamakesi nezimbobo ezivulekile.

Izici ezibalulekile ze-slip-on welded solid bodyama-centralizers aqinilezizenze zibe yimpahla ebalulekile emsebenzini wokwakha nowokuqeda. Ikhono labo lokuhlinzeka ngamandla amakhulu asekelayo liqinisekisa ukuthi i-casing ihlala endaweni, ngisho nasezimweni ezinzima zokubhoboza kahle.

Emithonjeni echezukile nevundlile, lapho ukugcina ukuqina kwebhokisi kungase kube inselele, lezi zinto ezimaphakathi zinikeza isisombululo esithembekile. Ukwakhiwa kwazo okuqinile nokuklama okuphumelelayo kuzenza zikufanelekele kahle ukuphatha ubunkimbinkimbi bamajiyometri abhoboke kahle, okuqinisekisa ukuthi ikesi lihlala ligxile kahle futhi lisekelwe kulo lonke ukwehla.

Ngaphezu kwalokho, ukuguquguquka komzimba oqinile oshibilikisiweama-centralizers aqinileibenza bafaneleke ezinhlobonhlobo zezinhlelo zokusebenza, kufaka phakathi ukugqagqana kwe-liner kanye nokuhlanganisa izicathulo. Lokhu kuzivumelanisa nezimo kuvumela ukusetshenziswa kwabo ngempumelelo ezimeni ezihlukahlukene zokwakha imithombo, kunikeze ukusebenza okungaguquki nokwethembeka.

Sengiphetha, umzimba oqinile oshibilikisiweama-centralizers aqinileziyithuluzi elibalulekile lokuthuthukisa ukuzinza kwe-casing ezimweni eziyinselele zemigodi yemithombo. Amandla azo aphezulu asekelayo, amandla okuqala aphansi, kanye nokusebenza okuguquguqukayo kuwenza abe yinketho ethembekile yokuqinisekisa ukwehla okushelelayo nokuma kahle kwekesi emisebenzini ehlukahlukene yokwakha nokuqedwa kwemithombo.
