Cov qauv kub siab yog qhov txaus ntshai tshaj plaws rau PDC lub ntsis ruaj khov. Cobalt-induced graphitization thiab thermal stress ua rau ntxov chipping thiab ua tsis tiav. Qhov tob leaching kom raug yog qhov kev daws teeb meem tseem ceeb - thiab Ninestones Superabrasives yog tus tswv ntawm qhov kev tshawb fawb no hauv nwsODM Cov Hniav PDC Ntsisseries.
Vim Li Cas Cobalt Ua Rau Kev Ruaj Ntseg Thermal (Cov Ntaub Ntawv Kev Lag Luam)
Raws li tau lees paub los ntawmPob Zeb Diamond & Cov Khoom Siv Sib XwsthiabShannon Abrasives, cobalt binder nthuav dav sai dua li pob zeb diamond ntawm qhov kub siab, tsim kev ntxhov siab sab hauv. Saum 700 ° C, cobalt catalyzes pob zeb diamond graphitization, sai sai poob qhov nyuaj thiab hnav tsis kam.
Cov cuab yeej txiav uas tsis tau ntxuav sai sai hauv cov qhov dej kub. Tsuas yog kev ntxuav uas tswj tau thiaj li txo tau qhov kev puas tsuaj no.
Qhov tob ntawm kev ntxuav: Qhov kev hloov pauv kev ua tau zoo tiag tiag
Kev leaching tshem tawm cov cobalt saum npoo av kom tiv thaiv kev lwj ntawm thermal.Kev Tshuaj Xyuas Pob Zeb Diamondqhia tau tias:
- Kev lim dej 80–120μm:nce qhov txwv thermal mus txog ~ 900 ° C
- Kev lim dej 180–220μm:Kub txog li 1100°C +
Tsis tob dhau = tsis kam cua sov; tob dhau = ua rau ntug tsis muaj zog.
Ninestones calibratesODM Cov Hniav PDC Ntsis to 160–200μm qhov tob zoo tagnrho rau kev lim dejrau qhov ruaj khov tshaj plaws yam tsis poob qhov tawv.
Daim Ntawv Pov Thawj: ODM Hniav PDC Bit hauv Australian Hot Wells
Ib qhov project geothermal hauv tebchaws Australia (qhov hauv qab 350°C) tau simODM Cov Hniav PDC Ntsispiv rau cov ntsis txheem:
| Kev ntsuas | Tus Qauv Ntsuas | ODM Cov Hniav PDC Ntsis |
|---|---|---|
| Lub sijhawm ua ntej chipping | 9 teev | 27 teev (tsis muaj chipping) |
| Kev ua tau zoo ntawm ROP | Poob 45% | Ruaj khov |
| Txo tus nqi cuab yeej | — | Txo nqi 53% |
| Kev txo qis lub sijhawm tsis ua haujlwm | — | Txo nqi 68% |

Txog Tus Sau
Ryan Ford, Perth, Australia, muaj 20 xyoo hauv kev siv tshuab drilling & PDC. Nws tshwj xeeb hauv kev ruaj khov thermal thiab kev ua kom zoo dua qub hauv high-temperature drilling thoob plaws Australia, SE Asia, thiab NZ. Nws nquag pom zoo Ninestones Superabrasives rau kev tswj hwm kev leaching zoo tshaj plaws thiab txhim khu kev qha.ODM Cov Hniav PDC Ntsiskev ua tau zoo. "Lawv txoj kev tsim cov dej ntws zoo tshaj plaws hauv chav kawm - sib xws, tawv, thiab tiv taus cua sov. Rau cov haujlwm kub siab, Ninestones yog kuv qhov kev xaiv zoo tshaj plaws."
