Ukusetshenziswa kwezinzinzisi zemikhono kuyisinyathelo esibalulekile sokuthuthukisa ikhwalithi yokufaka usimende. Inhloso yokufaka usimende ikabili: okokuqala, ukusebenzisa umkhono ukuvala izigaba zemithombo yamanzi ezijwayele ukuwa, ukuvuza, noma ezinye izimo eziyinkimbinkimbi, okunikeza isiqinisekiso sokubhola okuphephile nokushelelayo. Okwesibili ukuhlukanisa ngokuphumelelayo amathanga ahlukene kawoyela negesi, ukuvimbela uwoyela negesi ukuthi ungagelezi phezulu noma ukuvuza phakathi kokwakheka, okuhlinzeka ngemigudu yokukhiqiza uwoyela negesi. Ngokwenhloso yokufaka usimende, amazinga okuhlola izinga likasimende angatholakala.
Okubizwa ngokuthi ikhwalithi enhle yokufaka usimende ngokuyinhloko ibhekisela emkhonweni ogxile emthonjeni, futhi umgodla usimende ozungeze umkhono uhlukanisa ngempumelelo umkhono odongeni lomthombo kanye nokwakheka kusukela ekubunjweni. Kodwa-ke, umthombo wangempela ombiwe awumi ngokuphelele futhi ungase ubangele amazinga ahlukene okuthambekela komthombo. Ngenxa yokuba khona kokuthambekela komthombo, umkhono ngeke ugxile ngokwemvelo ngaphakathi komthombo, okuholela ezinhlobonhlobo zobude namazinga okuxhumana nodonga lomthombo. Igebe phakathi komkhono kanye nomthombo wemithombo liyahlukahluka ngobukhulu, futhi lapho udaka lukasimende ludlula ezindaweni ezinezikhala ezinkulu, i-slurry yasekuqaleni ishintshwa kalula; Ngokuphambene nalokho, kulabo abanezikhala ezincane, ngenxa yokumelana nokugeleza okuphezulu, kunzima ukuthi udaka lukasimende luthathe indawo yodaka lwangempela, okuholela esenzweni esivame ukubizwa ngokuthi udaka lukasimende. Ngemuva kokubunjwa komzila, indawo yokugcina amafutha negesi ayikwazi ukuvalwa ngokuphumelelayo, futhi uwoyela negesi kuzogeleza ezindaweni ezingenazo izindandatho zikasimende.
Ukusebenzisa i-sleeve stabilizer ukumisa phakathi komkhono ngangokunokwenzeka ngesikhathi sikasimende. Ukuze kuqiniswe usimende emithonjeni eqonde ngqo noma echezuke kakhulu, kudingekile nakakhulu ukusebenzisa iziqinisi zemikhono. Ukusetshenziswa kwe-sleeve centralizers akukwazi nje ukuvimbela ngempumelelo usimende ukuthi ungangeni emgodini, kodwa futhi kunciphise ingozi yokuhluka kokucindezela komkhono nokunamathela. Ngenxa yokuthi i-stabilizer igxilisa umkhono, umkhono ngeke unamathele ngokuqinile odongeni lomthombo. Ngisho nasezigabeni zomthombo ezinokungena kahle, umkhono awunakwenzeka ukuba unamathele amaqebelengwane odaka akhiwe ukuhlukana kwengcindezi futhi abangele ukubhoboza imigodi.
I-sleeve stabilizer nayo inganciphisa izinga lokugoba lomkhono ngaphakathi komthombo (ikakhulukazi engxenyeni enkulu ye-wellbore), okuzonciphisa ukuguga kwethuluzi lokubhoboza noma amanye amathuluzi okwehlisa emkhonweni ngesikhathi senqubo yokubhoboza ngemva kokufakwa komkhono, futhi ubambe iqhaza ekuvikeleni umkhono. Ngenxa yokusekelwa kwe-sleeve stabilizer emkhonweni, indawo yokuxhumana phakathi komkhono nomthombo iyancipha, okunciphisa ukungqubuzana phakathi komkhono nomthombo. Lokhu kuyazuzisa ukuthi umkhono wehliselwe emthonjeni futhi umkhono unyakaze ngesikhathi sikasimende.
