Casing Drilling ntsis kuj yog lub npe hu ua annular laum, nws yog ib qho kev lag luam, tsim tau thiab zoo siab qhov sib sib zog nqus qhov cuab yeej.Nws yog qhov zoo dua los siv casing drilling me ntsis rau machining lub qhov siab tshaj 50mm hauv txoj kab uas hla.Cov cuab yeej no siv tau rau cov xwm txheej hauv qab no:
(1) Qhov txoj kab uas hla yog 50 hli saum toj no, thiab nrog rau kev ua siab ntev ntawm kev ncaj thiab txoj hauj lwm precision
(2) Qhov ntev-rau-inch qhov sib piv ntawm lub qhov yog nyob rau hauv thaj tsam ntawm 1 ~ 75, nws yog qhov kev xaiv zoo dua los siv casing drilling ntsis taub hau dua lwm txoj kev machining.
(3) Cov khoom siv ua haujlwm yog kim heev thiab cov tub ntxhais xav tau kev ntsuas thiab tshuaj ntsuam xyuas, thiab tag nrho cov tub ntxhais mandrel yuav tsum tau tshwj tseg.
(4) Lub tshuab fais fab tsis txaus yog tias drilling lub qhov loj, yog li trepanning yog qhov kev xaiv zoo.Nws yog haum rau txoj kab uas hla ntawm 50 mus rau 600mm (thematching toolbar yuav tsum tau deployed).
