Intambwe yo gukurura biti ni imyitozo ya biti isanzwe igenewe gukoreshwa muburyo bworoshye nkumucanga, ibumba, cyangwa urutare rworoshye.Ariko, ntibazakora neza mumabuye manini cyangwa amabuye akomeye.Imikoreshereze irimo gucukura amariba y'amazi, ubucukuzi, geothermal.ibidukikije hamwe nubushakashatsi.Igihe cyose bishoboka, bigomba gukoreshwa mu gucukura umwobo windege kuko bitanga ibiti byoroshye kwinjira.
Amababa 3 intambwe yo gukurura bits ni igice kimwe cyubaka ibyuma bivanze hamwe na tungsten karbide yo gukata hamwe nimpande zapima kugirango ubeho igihe kirekire.Ifite amababa 3 nu mwobo 3 utemba.Ugereranije n'amababa 4, amababa 3 intambwe yo gukurura bits ikunda gutobora byihuse kandi bikaze, mugihe, bigufi biramba kandi ntibiramba.3 amababa yintambwe yuburyo bwo gukurura bits bizana imbaraga nini zo gutema kuruta chevron style gukurura bit.Imbonerahamwe yihuta ya step gukurura bits igomba kuba hagati ya 60 na 80 rpm hamwe nuburemere bworoshye kuri bit (WOB).
Amababa 3 gukurura bits ni ibikoresho byubukungu mugihe cyo gucukura imiterere yoroheje ya geologiya hamwe nubujyakuzimu butaremereye, byashizweho mbere na mbere kubutaka bworoshye bwa tomedium, nk'ibumba, Loam, Silt, Mostsoft-kugeza hagati yubutaka bufite ubuhehere, nibindi. basabwe gucukura mu bucukuzi bw'amabuye y'agaciro, Ubushakashatsi, Ibidukikije, Iriba ry'amazi, Guhana Geo, n'ibindi.
Icyitonderwa: Diameter nuudodo byerekanwe nkuko byavuzwe haruguru nubunini busanzwe, ubundi bunini burahari bisabwe.
