Ubwihindurize bwa PDC

Mw'isi yo gucukura, ubwihindurize bwa PDC (polycrystalline diamant compact) bwahinduye umukino mubikorwa bya peteroli na gaze. Mu myaka yashize, abakata PDC bagize impinduka zikomeye mubishushanyo mbonera no mumikorere, kunoza imikorere no kwagura ubuzima bwabo.

Ku ikubitiro, amashanyarazi ya PDC yashizweho kugirango atange uburyo burambye kandi bunoze bwo gukoresha karbide gakondo ya tungsten. Bamenyekanye bwa mbere mu myaka ya za 70 kandi bahita bamenyekana cyane kubera ubushobozi bwabo bwo guhangana nubushyuhe bwo hejuru hamwe nigitutu mubisabwa byimbitse. Nyamara, abakata PDC kare bagarukiraga kuri kamere yabo yoroheje kandi bakundaga gucika no kumeneka.

Uko ikoranabuhanga ryateye imbere, abayikora batangiye kugerageza nibikoresho bishya nibishushanyo mbonera kugirango banoze imikorere ya PDC. Kimwe mu bintu byingenzi byateye imbere ni ugutangiza amashanyarazi ya polycrystalline ihamye (TSP). Ibyo byuma byagaragazaga urwego rwa diyama rukomeye kandi rwashoboraga kwihanganira ubushyuhe bwinshi n’umuvuduko mwinshi kuruta amashanyarazi ya PDC.

Iyindi ntambwe ikomeye yatewe muri tekinoroji ya PDC ni ugutangiza imashini ivanga. Utwo dukata twahujije uburebure bwa PDC hamwe nuburemere bwa karubide ya tungsten kugirango ikore igikoresho cyo gukata gishobora no gukemura ibibazo bigoye cyane.

Mu myaka yashize, iterambere mu buhanga bwo gukora ryemereye gukora geometrike igoye mu bice bya PDC. Ibi byatumye habaho iterambere ryimashini zabugenewe zagenewe gukoreshwa mu buryo bwihariye, nko gucukura icyerekezo hamwe n’umuvuduko mwinshi / gucukura ubushyuhe bwo hejuru.

Imihindagurikire y’ibiti bya PDC yagize ingaruka zikomeye ku nganda za peteroli na gaze. Nubushobozi bwabo bwo kwihanganira ibihe bikabije kandi bimara igihe kinini kuruta ibikoresho byo gutema gakondo, abakata PDC bongereye ubushobozi bwo gucukura no kugabanya igihe. Mugihe tekinoroji yo gucukura ikomeje gutera imbere, birashoboka ko tuzabona andi majyambere mugushushanya kwa PDC no gukora.

Mu gusoza, abakata PDC bageze kure kuva batangira muri za 1970. Kuva mu minsi yabo ya mbere nkuburyo burambye bwo gushiramo karbide ya tungsten, kugeza mugutezimbere ibyuma byabugenewe byabugenewe byo gucukura, ubwihindurize bwibiti bya PDC ntakintu cyabaye gito cyane. Mu gihe inganda za peteroli na gaze zikomeje gutera imbere, abakata PDC nta gushidikanya bazagira uruhare runini mu gutwara neza no gutanga umusaruro mu bikorwa byo gucukura.
