The downhole stabilizer ke sengoathoana sa lisebelisoa tsa ho theola sekoti se sebelisoang ka har'a mokoting oa lesoba le ka tlase (BHA) la khoele ea ho phunya. E tsitsisa BHA ka har'a sekoti ka mochini e le ho qoba ho kheloha ka boomo, ho sisinyeha, le ho netefatsa boleng ba sekoti se phuntsoeng. E entsoe ka 'mele o se nang letho oa cylindrical le mahare a tsitsitseng, ka bobeli a entsoe ka tšepe e matla haholo. Li-blades li ka ba tse otlolohileng kapa tse pota-potiloeng, 'me li na le sefahleho se thata bakeng sa ho hanyetsa ho apara.
Ho na le haholo mefuta e meraro ea li-stabilizers tsa ho cheka tse sebelisoang sebakeng sa oli kajeno.
1. Integral stabilizer, e entsoeng ka ho feletseng ho tsoa ho karolo e le 'ngoe ea tšepe. Mofuta ona o atisa ho ba o tloaelehileng le o sebelisoang haholo.
2. Replaceable sleeve stabilizer, moo mahare a leng teng holim'a sleeve, e ntan'o phunyeletsoa 'meleng. Mofuta ona o ka ba oa moruo ha ho se na lisebelisoa tsa ho lokisa haufi le seliba se chekang.
3. Li-welded blades stabilizer, moo mahare a cheselitsoeng holim'a 'mele. Hangata mofuta ona ha o elelloe ka liliba tsa oli ka lebaka la likotsi tsa ho lahleheloa ke li-blades, empa hangata o sebelisoa ha ho cheka liliba tsa metsi kapa libakeng tsa oli tse theko e tlaase.
Hangata li-stabilizer tse 2 ho isa ho tse 3 li kenngoa ka har'a BHA, ho kenyelletsa le e 'ngoe feela ka holim'a sekoti sa ho phunya (haufi-bit stabilizer) le e le' ngoe kapa tse peli har'a melala ea ho cheka (li-string stabilizers).
Le hoja ts'ebetso ea ho phunya e ka ba e rarahaneng le e kotsi, tšebeliso ea stabilizer ea ho phunya e fokotsa haholo kotsi ea mathata a ho phunya, ho netefatsa hore mokhoa oa ho phunya o tsamaea hantle le ka katleho.
Matla a lula a tsitlella ho etsa litšebeletso tsa boleng bo phahameng le lihlahisoa tsa boleng bo phahameng, haeba u thahasella lisebelisoa tsa ho theola oli le khase, ka kopo u se ke ua tsilatsila ho ikopanya le rona.
