Gucukura Stabilisateur Ibikoresho bya BHA
Stabilisateur yo gucukura ni igice cyibikoresho byo hasi bikoreshwa mugiterane cyo hasi (BHA) cyumugozi wimyitozo. Ihindura uburyo bwa BHA mu mwobo kugirango hirindwe kunyura ku bushake, kunyeganyega, no kwemeza ubwiza bw’umwobo burimo gucukurwa.
Igizwe numubiri wa silindrike wuzuye kandi ikomeza ibyuma, byombi bikozwe mubyuma bikomeye. Icyuma kirashobora kuba kigororotse cyangwa kizunguruka, kandi kirakomeye kugirango kirinde kwambara.
Ubwoko butandukanye bwo gucukura burakoreshwa mubutaka bwa peteroli uyumunsi. Mugihe stabilisateur integral (yakozwe neza mugice kimwe cyicyuma) ikunda kuba ihame, ubundi bwoko burashobora gukoreshwa, nka:
Gusimbuza amaboko ya stabilisateur, aho ibyuma biherereye ku ntoki, hanyuma bigahinduka ku mubiri. Ubu bwoko burashobora kuba ubukungu mugihe nta bikoresho byo gusana biboneka hafi y'iriba rucukurwa kandi hagomba gukoreshwa imizigo yo mu kirere.
Icyuma gisudira stabilisateur, aho ibyuma bisudira kumubiri. Ubu bwoko ntibusanzwe bugirwa inama kumariba ya peteroli bitewe ningaruka zo gutakaza ibyuma, ariko bikoreshwa buri gihe mugihe cyo gucukura amariba yamazi cyangwa kubutaka bwa peteroli buhendutse.
Mubisanzwe stabilisateur 2 kugeza kuri 3 zishyirwa muri BHA, harimo imwe iri hejuru ya biti ya drill (hafi-bit stabilisateur) na imwe cyangwa ebyiri hagati ya cola (stabilisateur)
