Drilling Stabilizer Downhole Equipment ya BHA
Pobowola stabilizer ndi chidutswa cha zida zapabowo zomwe zimagwiritsidwa ntchito pobowola pansi (BHA) pa chingwe chobowola.Imakhazikika bwino BHA m'borehole pofuna kupewa kudodometsa mwangozi, kugwedezeka, ndikuwonetsetsa kuti dzenje lomwe likubowoledwa bwino.
Amapangidwa ndi thupi lopanda kanthu la cylindrical ndi masamba okhazikika, onse opangidwa ndi chitsulo champhamvu kwambiri.Masambawo amatha kukhala owongoka kapena ozungulira, ndipo amakhala olimba kuti asavale.
Mitundu ingapo ya ma stabilizers obowola amagwiritsidwa ntchito masiku ano.Ngakhale zokhazikika zokhazikika (zopangidwa mokwanira kuchokera kuchitsulo chimodzi) zimakhala zokhazikika, mitundu ina ingagwiritsidwe ntchito, monga:
Replaceable manja stabilizer, kumene masamba zili pa manja, amene ndiye wononga pa thupi.Mtundu uwu ukhoza kukhala wandalama ngati palibe zokonzera zomwe zilipo pafupi ndi chitsime chobowoleredwa komanso katundu wonyamula mpweya ayenera kugwiritsidwa ntchito.
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)
