Ko te taputapu PDC reamer (Polycrystalline Diamond Compact reamer) he taputapu kore-awa tino whai hua mō te keri huarahi whakapae (HDD), e whakamahia ana hei whakanui i ngā poka wai paipa mō te tāutanga paipa me te kore keri mata. He taputapu tapahi PDC pumau ōna, e whakamahia whānuitia ana i roto i ngā kaupapa ratonga tāone, hinu/hau me te whakawhiti awa.
Ko ōna wāhanga matua ko ngā taputapu tapahi PDC tino mārō, he tinana maitai totoka kotahi te wahi (he iti te mōrearea o te rahunga) me ngā putanga waipēhi (mō te tango me te whakamatao i ngā tapahi). Ka mahi mā te hurihuri hei whakanui i ngā kōhao pairati ki te diameter ūnga i muri i te keri pairati.
- Teitei te whai huatanga: 30–60% tere ake i ngā mīhini riu tuku iho, e penapena ana i te wā o te kaupapa.
- Te roa o te ora mahi: Ka ātete ngā tapahi PDC ki te pakū, ka whakaiti i te whakakapinga taputapu.
- He pai mō te taiao: Kāore e keria te mata, he pai mō ngā tāone nui.
- He whai hua te utu: He iti ake te utu whakahaere mā te whakaiti i te wā me te mahi o te taputapu.
Ngā whakamahinga noa: Te whakatakoto paipa tāone, te whakawhiti awa/rori i ngā kaupapa HDD. Tauira purongo: I whakaitihia e te mīhini reamer PDC hou te wā hanga mā te 40% i roto i tētahi kaupapa paipa wai tāone, ā, ka ārai i te katinga o ngā rori.
