cobhsaitheoir druileála teaghrán lann bíseach lárnach
Cur síos:
Is cobhsaitheoir rothlach aon-phíosa é an Cobhsaitheoir Integral Blade (IBS) is féidir a chur in aice leis an giotán nó suas sa teaghrán druileála. Is tógáil aon-phíosa é a mhonaraítear as cruach cóimhiotail ard-neart (cruach neamh-mhaighnéad roghnach). Cuireann sé cosc ar ghreamú difreálach ar an sreang druileála tríd an BHA a chobhsú agus coiléar druileála agus píopaí druileála a choinneáil ar shiúl ó bhalla an tollphoill. Laghdaíonn sé seo creathadh, guairneán píopa druileála, agus tortuosity wellbore; ina theannta sin, coinníonn an cobhsú trajectory druileála cibé an druileáil toibreacha díreach, cothrománach nó treo.
