Chotsitsa pansi ndi chida chapansi chomwe chimagwiritsidwa ntchito pobowola pansi (BHA) pa chingwe chobowola. Imakhazikika pamakina a BHA m'borehole kuti apewe kudodometsa, kugwedezeka mwangozi, ndikuwonetsetsa kuti dzenje lomwe likubowoledwa bwino. Limapangidwa ndi thupi lopanda kanthu komanso masamba okhazikika, onse opangidwa ndi chitsulo champhamvu kwambiri. Masambawo amatha kukhala owongoka kapena ozungulira, ndipo amakhala olimba kuti asavale.
Pali mitundu itatu yambiri ya zolimbitsa thupi zomwe zimagwiritsidwa ntchito m'malo opangira mafuta masiku ano.
1. Integral stabilizer, yomwe imapangidwa mokwanira kuchokera kuchitsulo chimodzi. Mtundu uwu umakonda kukhala wamba komanso wogwiritsidwa ntchito kwambiri.
2. Replaceable sleeve stabilizer, kumene masamba ali pa manja, amene ndiye wononga pa thupi. Mtundu uwu ukhoza kukhala wachuma pamene palibe malo okonzera omwe alipo pafupi ndi chitsime chobowoleredwa.
3. Welded masamba stabilizer, kumene masamba welded pa thupi. Mtundu uwu nthawi zambiri sulangizidwa pazitsime zamafuta chifukwa cha kuopsa kwa masamba, koma amagwiritsidwa ntchito nthawi zonse pobowola zitsime zamadzi kapena pamafuta otsika mtengo.
Kawirikawiri 2 mpaka 3 stabilizers amaikidwa mu BHA, kuphatikizapo imodzi pamwamba pa kubowola (pafupi-bit stabilizer) ndi imodzi kapena ziwiri pakati pa makola obowola (zingwe zokhazikika).
Ngakhale kuti ntchito zobowola zingakhale zovuta komanso zowopsa, kugwiritsa ntchito pobowola stabilizer kumachepetsa kwambiri chiopsezo cha kubowola, kuonetsetsa kuti kubowola kumayenda bwino komanso moyenera.
Mphamvu nthawi zonse zimaumirira kuchita ntchito zapamwamba komanso zinthu zapamwamba, ngati mukufuna zida zotsitsa mafuta ndi gasi, chonde musazengereze kulumikizana nafe.
