Nibihe bikoresho bigomba gukoreshwa mu gucukura muri geologiya y’ikirere

1. Igikoresho cyo gucukura gifite ibikoresho byo guterana cyangwa gufatanya kelly bar, bishobora guhura na diameter yikirundo nuburebure bwikirundo.

2. Kelly Bar: hitamo ubwoko bwumuyoboro wa drill ukurikije imbaraga zurutare rwikirere cyane (metero 1 yikirundo cya pile, urugero), ubushobozi bwo gutwara burenze munsi ya 500 kPa hamwe na kelly bar; hejuru ya 500 kPa hamwe no guhuza kelly bar.

3. Ibikoresho byo gucukura: Byinshi mubutare bwikirere bukabije birashobora gutoborwa hamwe nindobo-ibiri-yinyo y amenyo yamasasu; ibikoresho byo gucukura kabiri-cone birashobora kandi gukoreshwa mugucukura byumye. Iyo ubushobozi bwo gutwara ibintu buzamutse bugera kuri 600 kPa - 900 kPa, birakenewe gukoresha umwitozo wa karitsiye yo gukata impeta, ariko ntibishoboka gufata cores, bityo rero birakenewe ko wongera gukoresha inshuro ebyiri hasi.

4. Amenyo yo gucukura: 30 / 50.22 amenyo yamasasu na 4S amenyo yamasasu ayobora amenyo akoreshwa mugutobora ikirere gikabije, gifasha kumenagura, kugabanya kurwanya gucukura, no kugabanya igihombo neza.
