Usimende usekela futhi uvikele ama-casings kahle futhi usiza ukuzuza ukuhlukaniswa kwendawo.Okubalulekile emithonjeni ephephile, ezwakalayo engokwemvelo, kanye nenenzuzo, ukuhlukaniswa kwendawo kuyakhiwa futhi kugcinwa emthonjeni ngenqubo yokufaka usimende.Ukuhlukaniswa kwendawo kuvimbela uketshezi olufana namanzi noma igesi endaweni eyodwa ukuthi lungahlangani namafutha kwenye indawo.Lokhu kufezwa ngokwakhiwa komgoqo we-hydraulic phakathi kwe-casing, usimende nokwakheka.Izithasiselo zikasimende ziyizinto ezifakwa kusimende ukuze kuthuthukiswe izakhiwo zikasimende kanye nenqubo yokugaya usimende.Izithasiselo zikasimende zihlukaniswa ngamaqembu emikhiqizo ehlukene njengezinsiza zokugaya, izithuthukisi zamandla nezithuthukisi zokusebenza.Kunezinhlobo ezimbili eziyisisekelo zemisebenzi yokufaka usimende, okungukuthi, ukufaka usimende okuyisisekelo nokwesibili.I-cementing eyinhloko ilungisa i-casing yensimbi ekubunjweni okuzungezile.I-cementing yesibili isetshenziselwa ukugcwalisa ukwakheka, ukuvala uphawu, noma ukuvala amanzi.Ukusebenza kungahluka ngokungezwa kwezithasiselo maqondana nezici ezahlukahlukene.Kuye ngokusetshenziswa kukasimende, izinhlobonhlobo eziningi zezithasiselo zingafakwa.Lokhu kufaka phakathi ama-accelerator, ama-retarders, ama-dispersant, ama-extender, ama-weighting agents, ama-gel, amagwebu, nezithasiselo zokulahlekelwa uketshezi.I-Foring Chemcials inikezela ngezinhlobonhlobo zezithasiselo zamakhemikhali ezikhethekile ezisezingeni eliphezulu ezisetshenziswa endaweni kawoyela futhi ihlinzeka ngomklamo owenziwe ngendlela efanele ukusekela nokuthuthukisa inqubo yokufaka usimende.Izisabalalisi zikasimende zithuthukisa i-rheology ye-slurry ukuze ukumpompa ibanga elide kuthuthukiswe kakhulu futhi ngesikhathi esifanayo ama-slurries kasimende ancishisiwe kungenzeka.Izithasiselo zokulahlekelwa kwamanzi, ezizinzile ngokumelene namazinga okushisa aphezulu kanye nezixazululo zikasawoti ezigxilile, ziqinisekisa umsebenzi othembekile wokuhlanganisa ngaphansi kwezimo ezinzima.Ama-retarders angahlanganiswa ngokuhambisana nezihlakaniphi zethu ezisebenza kahle kakhulu okuvumela isikhathi esibalulekile semisebenzi yokufaka usimende ngaphansi kwezimo zokushisa eziphezulu.Izithasiselo ezilwa nokufuduka kwegesi zivimbela igesi ukuthi ingangeni kusimende oqinisayo futhi iqinisekisa umsebenzi onokwethenjelwa kasimende, kuyilapho ama-defoam ethu enezinto ezivelele zokulawula igwebu.
