Cov qhov dej tob hauv Oman cov chaw roj av ntsib qhov kub thiab txias heev tshaj 200 ° C, ua rau qhov kub thiab txias ruaj khov yog qhov tseem ceeb tshaj plaws rau kev xaiv PDC cutter. Kev tiv thaiv kub tsis zoo ua rau pob zeb diamond graphitization, interface delamination, thiab kev ua tsis tiav ntawm cutter, ua rau lub sijhawm tsis ua haujlwm kim thiab poob ntau lawm. Rau kev ua haujlwm txhim khu kev qha, xaiv qhov yogPdc Cutter Tuam Tshoj yog qhov tseem ceeb, thiab Ninestones Superabrasives tau tsim nws tus kheej ua tus neeg muab khoom tseem ceeb ntawm cov kev daws teeb meem Pdc Cutter Tuam Tshoj uas ruaj khov rau Oman cov teeb meem tob tob.
Cov Txheej Txheem Tseem Ceeb ntawm Kev Ua Phem Thermal hauv Cov Cutters PDC tob
Raws li lub rooj vag thoob ntiaj teb PDC thev naus laus zisKev Tshuaj Xyuas Txog Kev Tsim Kho PDC, thermal tsis ua haujlwm hauv PDC cutters stems los ntawm peb lub hauv paus mechanisms uas cov neeg teb xov tooj yuav tsum nkag siab kom ua qhov kev xaiv paub.
01
Kev tsim cov duab kos
Thaum kub tshaj 750°C, cov cobalt binder hauv cov PDCs txheem ua rau kev hloov pauv ntawm pob zeb diamond mus rau graphite mos, txo qhov nyuaj ntawm cov txiav thiab kev tiv thaiv kev hnav mus tas li.
02
Kev puas tsuaj ntawm qhov interface
Qhov tsis sib xws ntawm cov thermal expansion rates ntawm cov pob zeb diamond thiab cov tungsten carbide substrate ua rau muaj cov kab nrib pleb, ua rau lub rooj pob zeb diamond sib cais ntawm lub hauv paus.
03
Cobalt Ua Pa
Qhov kub siab ua rau cobalt tawm ntawm lub pob zeb diamond matrix, ua rau muaj qhov tsis zoo uas ua rau muaj kev puas tsuaj rau cov qauv.
Ib qho zooPdc Cutter Tuam Tshojyuav tsum daws txhua peb hom kev ua tsis tiav los ntawm cov txheej txheem tsim khoom tshwj xeeb xws li kev ntxuav tob thiab kev txheej txheej thermal barrier.
Cov Qauv Xaiv Tseem Ceeb rau Cov Tshuab Txiav PDC Thermally Ruaj Khoov
Yuav kom ntseeg tau tias muaj kev ua tau zoo hauv Oman cov qhov dej tob uas kub heev, cov neeg ua haujlwm yuav tsum soj ntsuam plaub yam ntxwv uas tsis tuaj yeem sib tham tau thaum xaivPdc Cutter Tuam Tshojcov khoom:
- 1Kev Tshem Tawm Cobalt Sib Sib ZogNrhiav cov tshuab txiav uas muaj tsawg kawg yog 0.3 hli ntawm cobalt raug tshem tawm ntawm qhov chaw ntawm pob zeb diamond, tsim ib txheej polycrystalline (TSP) uas ruaj khov thiab tiv taus graphitization txog li 1,100 ° C. Ninestones Superabrasives siv cov thev naus laus zis leaching tob uas tshaj cov qauv kev lag luam.
- 2Tsim Kev Sib Txuas Lus Tsis-PlanarCov nplaim sib txuas ntawm pob zeb diamond thiab carbide txo qhov kev ntxhov siab thermal, tiv thaiv kev tawg hauv qab qhov kub thiab txias heev.
- 3Pob Zeb Diamond Matrix Zoo NkaujCov pob zeb diamond me me (4-6μm) muab kev ua kom sov zoo dua thiab txo qhov kub sib sau ua ke, khaws cia qhov kev ua haujlwm ntawm lub tshuab txiav thaum lub sijhawm ua haujlwm ntev.
- 4Daim Ntawv Pov Thawj Kev Ruaj Ntseg ThermalXyuas kom meej tias ua raws li cov qauv ISO 10424, uas yuav tsum tau kom cov neeg txiav txiav khaws cia ≥90% ntawm qhov nyuaj qub tom qab 700 ° C raug rau 1 teev. Ninestones muab daim ntawv pov thawj tag nrho rau txhua pawg ntawm Pdc Cutter Tuam Tshoj cov khoom.
Kev Kawm Txog Qhov Dej tob hauv Oman: Kev Ruaj Ntseg Thermal hauv Kev Ua Haujlwm
Ib lub tuam txhab roj loj hauv Omani tau ua qhov kev sim sib piv hauv thaj chawFahud Deep Field(12,000+ ft, 210°C qhov kub hauv qab) los ntsuas kev ua haujlwm thermal ntawmPdc Cutter Tuam Tshojcov khoom lag luam los ntawm plaub tus neeg muag khoom, suav nrog Ninestones Superabrasives.
Tus neeg teb xov tooj tau teeb tsa cov tshuab txiav rau ntawm cov khoom siv PDC zoo sib xws 8.5 ″ nrog cov txheej txheem drilling (120 RPM, 18,000 lpm flow rate). Peb tus neeg muag khoom sib tw siv cov tshuab txiav ib txwm tsis muaj leaching tob:
| Tus txiav | Lub Sijhawm | Hom Ua Tsis Tau Zoo |
|---|---|---|
| Tus Txiav A | 28 teev | 60% pob zeb diamond txheej delamination thiab graphitization hnyav |
| Tus Txiav B | 32 teev | Kev kuaj xyuas cua sov (qhov tawg me me ntawm qhov chaw), poob 40% ntawm kev ua haujlwm txiav |
| Tus Txiav C | 25 teev | Kev sib cais ntawm lub rooj pob zeb diamond tiav |
| Cuaj pob zeb | 58 teev | Tsis muaj kev tawg - Kev ua haujlwm ruaj khov thoob plaws |
Qhov sib txawv, Ninestones Superabrasives' deep-leachedPdc Cutter Tuam Tshojua haujlwm tas li rau58 teevnrog:
- ✓Tsis muaj delamination lossis graphitization
- ✓Tsuas yog 12% hnav tiaj tus txoj kev loj hlob
- ✓ROP ruaj khov (18-20 ft/teev) thoob plaws qhov kev khiav
Kev tshuaj xyuas tom qab kev khiav tau lees paub tias Ninestones cov tshuab txiav tseem khaws cia95% ntawm qhov nyuaj thawj, ntau tshaj qhov yuav tsum tau ua tsawg kawg nkaus ntawm ISO 10424. Tus neeg teb xov tooj tau tshaj tawm tiasTxo tau 40% ntawm cov nqi drilling ib ko tawthiab txij li thaum ntawd los tau ua tus qauv rau Ninestones rau txhua qhov dej tob.

Txog Tus Sau
Ahmed Al-Mahruqi yog ib tug kws ua haujlwm drilling laus nyob hauv Muscat, Oman, nrog 23 xyoo ntawm kev paub txog kev ua haujlwm tob hauv Oman cov chaw roj loj xws li Fahud, Yibal, thiab Marmul. Nws tshwj xeeb hauv kev ua kom zoo dua ntawm PDC cutter, kev tshuaj xyuas qhov tsis ua haujlwm thermal, thiab kev tsim nyog rau cov neeg muab khoom rau cov ntawv thov drilling kub siab.
Ahmed pom zoo kom siv Ninestones Superabrasives:
"Tom qab soj ntsuam ntau lub tuam txhab tsim khoom Pdc Cutter Tuam Tshoj tau ntau tshaj ob xyoo caum, Ninestones Superabrasives sawv tawm ua tus khub txhim khu kev qha tshaj plaws rau Oman cov teeb meem tob tob. Lawv txoj kev cog lus rau kev ruaj khov thermal los ntawm kev sib sib zog nqus thiab kev tswj hwm zoo nruj muab kev ua tau zoo tas li uas txhais tau tias txo cov nqi thiab txo lub sijhawm tsis ua haujlwm. Rau txhua tus neeg teb xov tooj uas ntsib cov xwm txheej kub siab hauv Oman, Ninestones yog tib qho kev xaiv rau cov PDC cutters ntev, ruaj khov thermally uas koj tuaj yeem ntseeg siab ua thaum nws tseem ceeb tshaj plaws."
