stabilizzatur integrali tat-tħaffir tas-sekwenza ta 'xafra spirali
Deskrizzjoni:
L-Istabilizzatur Integral tax-Xafra (IBS) huwa stabilizzatur li jdur f'biċċa waħda li jista 'jitqiegħed ħdejn il-bit jew 'il fuq fil-korda tat-drill. Hija kostruzzjoni f'biċċa waħda manifatturata minn azzar liga ta 'saħħa għolja (azzar mhux kalamita mhux obbligatorju). Tipprevjeni t-twaħħil differenzjali tas-sekwenza tat-tħaffir billi tistabbilizza l-BHA u żżomm kullari tat-tħaffir u pajpijiet tat-tħaffir 'il bogħod mill-ħajt tal-borehole. Dan inaqqas il-vibrazzjoni, drill pipe whirl, u wellbore tortuosity; barra minn hekk, l-istabbilizzazzjoni żżomm it-trajettorja tat-tħaffir kemm jekk tħaffir bjar dritti, orizzontali jew direzzjonali.
