PDC reamer (Polycrystalline Diamond Compact reamer) chishandiso chinoshanda nesimba chekuchera maburi nenzira yakatwasuka (HDD), chinoshandiswa kuwedzera mabhora ekuisa mapaipi pasina kucherwa pamusoro. Chine zvicherwa zvePDC zvakagadzika, zvinoshandiswa zvakanyanya mumapurojekiti emagetsi emumaguta, mafuta/gasi uye kuyambuka rwizi.
Zvikamu zvayo zvikuru zvinosanganisira zvicheki zvePDC zvakasimba, muviri wesimbi yakasimba ine chidimbu chimwe chete (njodzi shoma yekukundikana) uye ma hydraulic ports (ekubvisa zvicheki nekutonhodza). Inoshanda nekutenderedza kuti ikure maburi emuchina wepilot kusvika padhayamita yakatarwa mushure mekuboorwa kwemuchina wepilot.
- Kushanda zvakanaka: 30–60% nekukurumidza kupfuura ma reamers echinyakare, zvichichengetedza nguva yepurojekiti.
- Hupenyu hurefu hwebasa: Zvicheki zvePDC zvinoramba kukweshwa, zvichideredza kutsiva maturusi.
- Inochengetedza nharaunda: Hapana kucherwa pamusoro, yakakodzera nzvimbo dzemaguta.
- Inochengetedza mari: Inoderedza mari yekushandisa kuburikidza nekuderedza nguva yekushanda nekushanda.
Mashandisirwo akajairika: Kuisa mapaipi muguta, mapurojekiti eHDD ekuyambuka rwizi/migwagwa. Muenzaniso wenhau: PDC reamer itsva yakaderedza nguva yekuvaka ne40% muchirongwa chemapaipi emvura muguta, zvichidzivirira kuvharwa kwemigwagwa.
Nguva yekutumira: Kubvumbi-18-2026
