Izithasiselo zokulawula ukulahlekelwa uketshezi ze-FC-600S
Kunezinhlobo ezimbili eziyisisekelo zemisebenzi yokufaka usimende, okungukuthi, ukufaka usimende kokuqala nokwesibili. Ukufaka usimende kokuqala kuqinisa i-casing yensimbi ekwakhekeni okuzungezile. Ukufaka usimende kwesibili kusetshenziselwa ukugcwalisa ukwakheka, ukuvala, noma ukuvala amanzi. Izithasiselo zokulahlekelwa uketshezi, ezizinzile ngokumelene namazinga okushisa aphezulu kanye nezixazululo zikasawoti ezigxilile, ziqinisekisa umsebenzi wokufaka usimende onokwethenjelwa ngaphansi kwezimo ezinzima.
• I-FC-600S iyisengezo sokulahlekelwa uketshezi lwe-polymer lwesimende esisetshenziswa emthonjeni wamafutha futhi sakhiwe yi-copolymerization ene-AMPS njenge-monomer eyinhloko enokumelana okuhle kokushisa nosawoti kanye nokuhlanganiswa namanye ama-monomer alwa nosawoti. Ama-molecule aqukethe inani elikhulu lamaqembu anamathela kakhulu njenge-CONH2, - SO3H, - COOH, edlala indima ebalulekile ekumelaneni nosawoti, ukumelana nokushisa, ukumuncwa kwamanzi mahhala, ukunciphisa ukulahleka kwamanzi, njll.
• I-FC-600S inokuguquguquka okuhle futhi ingasetshenziswa ezinhlelweni ezahlukene ze-simende slurry. Ihambisana kahle nezinye izithasiselo.
• I-FC-600S ifaneleka ekushiseni okubanzi okunokumelana nokushisa okuphezulu okufika ku-180℃. Ngemva kokusetshenziswa, ukugeleza kohlelo lwe-slurry lukasimende kuhle, kuzinzile ngoketshezi olukhululekile oluncane futhi ngaphandle kokuhlehlisa isethi namandla akhula ngokushesha.
• I-FC-600S ifaneleka ekulungiseleleni ukungcola kwamanzi ahlanzekile/amanzi anosawoti.

Sekuyiminyaka engaphezu kwengu-20, izinto zokulawula ukulahlekelwa uketshezi ziye zengezwa ezitsheni zesimende ezisebenzisa uwoyela futhi manje sekuyaziwa embonini ukuthi ikhwalithi yemisebenzi yokufaka usimende ithuthuke kakhulu. Ngempela, ngokuvamile kuyavunywa ngokucacile ukuthi ukuntuleka kokulawulwa kokulahlekelwa uketshezi kungaba yimbangela yokwehluleka kokuqala kokufaka usimende, ngenxa yokwanda kobuningi noma ukuvalwa kwe-annulus nokuthi ukuhlasela kokwakheka yi-cement filtrate kungaba yingozi ekukhiqizweni. Isengezo sokulahlekelwa uketshezi asikwazi nje ukulawula ngempumelelo ukulahlekelwa uketshezi kwesimende, kodwa futhi sivimbele ungqimba lukawoyela negesi ekungcolisweni uketshezi oluhlungiwe futhi ngaleyo ndlela kwandise ukusebenza kahle kokubuyisela esimweni saso.
Umbuzo 1 Uyini umkhiqizo wakho oyinhloko?
Ngokuyinhloko sikhiqiza izithasiselo zokufaka ukhonkolo kanye nokubhoboza imithombo yamafutha, njengokulawula ukulahleka koketshezi, i-retarder, i-dispersant, i-anti-gas migration, i-deformer, i-spacer, i-flushing liquid njll.
Umbuzo 2 Ungakwazi yini ukunikeza amasampula?
Yebo, singakunikeza amasampula amahhala.
Q3 Ungakwazi yini ukwenza ngokwezifiso umkhiqizo?
Yebo, singakunikeza imikhiqizo ngokwezidingo zakho.
UMBUZO 4 Amakhasimende akho ayinhloko avela kumaphi amazwe?
INyakatho Melika, i-Asia, iYurophu kanye nezinye izifunda.
