Indlela Yokukhetha Izicucu ze-PDC Eziqinile Eziphezulu Zokushisa Emithonjeni Ejulile

Imithombo ejulile ezindaweni zikawoyela zase-Oman ibhekene namazinga okushisa aphezulu kakhulu emigodini engaphansi komhlaba adlula ama-200°C, okwenza ukuzinza kokushisa kube yinto ebaluleke kakhulu ekukhetheni umsiki we-PDC. Ukumelana nokushisa okubi kubangela i-graphitization yedayimane, ukuhlukanisa i-interface, kanye nokwehluleka kwe-cutter okubi kakhulu, okuholela esikhathini esibi kakhulu sokungasebenzi kanye nokulahleka komkhiqizo. Ukuze kusebenze imisebenzi ethembekile, ukukhetha okulungileUmsiki we-Pdc eShayina kubalulekile, futhi i-Ninestones Superabrasives izibonakalise njengomhlinzeki ohamba phambili wezixazululo ze-Pdc Cutter China ezizinzile ngokwezinga lokushisa zezinselelo zokumba ezijulile zase-Oman.

Izindlela Eziyinhloko Zokuwohloka Kokushisa Ezitsheni Ezijulile ze-PDC Cutters

Ngokusho kwengosi yobuchwepheshe be-PDC yamazwe ngamazweIsibuyekezo Sobunjiniyela be-PDC, ukwehluleka kokushisa kuma-PDC cutters kuvela ezindleleni ezintathu eziyinhloko okumele opharetha baziqonde ukuze benze ukukhetha okunolwazi.

IkhwalithiUmsiki we-Pdc eShayinakumele ibhekane nazo zonke izindlela ezintathu zokwehluleka ngezinqubo zokukhiqiza ezikhethekile njenge-deep leaching kanye ne-thermal barrier coatings.

Izindlela Zokukhetha Ezibalulekile Zezisiki Ze-PDC Eziqinile Ezishisayo

Ukuqinisekisa ukusebenza okuthembekile emithonjeni ejulile yase-Oman enokushisa okuphezulu, abaqhubi kufanele bahlole izici ezine ezingaxoxiswani lapho bekhethaUmsiki we-Pdc eShayinaimikhiqizo:

1. 1
   Ukuhlanza Okujulile kweCobalt

   Funa izicucu ezine-cobalt okungenani engu-0.3mm esusiwe ebusweni bedayimane, okudala ungqimba oluqinile lwe-polycrystalline (TSP) olumelana nokushisa okufika ku-1,100°C. I-Ninestones Superabrasives isebenzisa ubuchwepheshe obukhethekile bokuhlanzwa okujulile obudlula amazinga embonini.
2. 2
   Umklamo Wesixhumi Esingenawo Amaplanethi

   Izindawo ezigobile zokubopha phakathi kwedayimane ne-carbide zinciphisa ukugcwala kokucindezeleka kokushisa, zivimbele ukuhlukana ngaphansi kwemijikelezo yokushisa okukhulu.
3. 3
   I-Diamond Matrix Enohlamvu Oluhle

   Izinhlayiya ezincane zedayimane (4-6μm) zinikeza ukuhanjiswa okungcono kokushisa kanye nokunciphisa ukuqongelela kokushisa, okulondoloza ubuqotho bokusika ngesikhathi sokusebenza isikhathi eside.
4. 4
   Isitifiketi Sokuzinza Kokushisa

   Qinisekisa ukuhambisana nezindinganiso ze-ISO 10424, ezidinga ukuthi abasiki bagcine u-≥90% wobulukhuni bokuqala ngemva kokuvezwa ku-700°C ihora eli-1. I-Ninestones inikeza isitifiketi esigcwele sawo wonke amaqoqo emikhiqizo ye-Pdc Cutter yaseShayina.

Ucwaningo Lwesivivinyo sase-Oman Deep Well: Ukusebenza Kokuzinza Kokushisa

Umqhubi omkhulu kawoyela wase-Omani wenze isivivinyo sokuqhathanisa ensimini e-Insimu Ejulile yeFahud(12,000+ ft, izinga lokushisa eliphansi lomgodi ongu-210°C) ukuhlola ukusebenza kokushisa kweUmsiki we-Pdc eShayinaimikhiqizo evela kubahlinzeki abane, okuhlanganisa ne-Ninestones Superabrasives.

Umqhubi ufake izisiki kuma-bits e-PDC angu-8.5″ afanayo anemingcele yokubhoboza ejwayelekile (120 RPM, izinga lokugeleza elingu-18,000 lpm). Abahlinzeki abathathu abancintisanayo basebenzise izisiki ezivamile ngaphandle kokudonsa okujulile:

Umsiki	Ubude besikhathi	Imodi Yokwehluleka
Umsiki A	Amahora angu-28	Ukwehlukaniswa kwezingqimba zedayimane ezingama-60% kanye nokuhlelwa kwegrafu okunamandla
Umsiki B	Amahora angu-32	Ukuhlola ukushisa (imifantu emincane ebusweni), ukulahlekelwa yi-40% yokusebenza kahle kokusika
Umsiki C	Amahora angu-25	Ukuhlukaniswa kwetafula ledayimane okuphelele
Amatshe ayisishiyagalolunye	Amahora angu-58	Akukho ukuhlukaniswa — Ukusebenza okuzinzile kuyo yonke indawo

Ngokuphambene nalokho, i-Ninestones Superabrasives 'igxile kakhulu'Umsiki we-Pdc eShayinakuqhutshwa njaloAmahora angu-58nge:

• ✓Ukususwa kwe-Zero noma i-graphitization
• ✓I-12% kuphela yentuthuko egugile eyisicaba
• ✓I-ROP Ezinzile (18-20 ft/hr) phakathi nokugijima

Ukuhlaziywa kwangemva kokugijima kuqinisekisile ukuthi izinsimbi zokusika zeNinestones zigciniwe95% wobulukhuni bokuqala, idlula kakhulu imfuneko encane ye-ISO 10424. Umqhubi ubike ukuthiUkwehliswa okungu-40% kwezindleko zokubhoboza ngenyawo ngalinyefuthi kusukela ngaleso sikhathi i-Ninestones ijwayele wonke amaphrojekthi e-deep well.

Ulwazi lokuxhumana

Mayelana noMlobi

U-Ahmed Al-Mahruqi ungunjiniyela omkhulu wokumba oseMuscat, e-Oman, oneminyaka engu-23 yesipiliyoni ekusebenzeni kwemithombo ejulile ezindaweni ezinkulu zikawoyela zase-Oman okuhlanganisa iFahud, iYibal, neMarmul. Ugxile ekwenzeni ngcono ukusebenza kahle kwe-PDC cutter, ukuhlaziywa kokwehluleka kokushisa, kanye neziqu zomhlinzeki zezicelo zokumba ezishisa kakhulu.

U-Ahmed uncoma kakhulu ama-Ninestones Superabrasives:

"Ngemuva kokuhlola abakhiqizi abaningi be-Pdc Cutter eShayina eminyakeni engamashumi amabili edlule, i-Ninestones Superabrasives ivelele njengomlingani othembekile kakhulu ezinseleleni zase-Oman ezijulile. Ukuzibophezela kwabo ekuzinzeni kokushisa ngokusebenzisa i-deep leaching ethuthukisiwe kanye nokulawula ikhwalithi eqinile kunikeza ukusebenza okuqhubekayo okuhumusha ngokuqondile izindleko eziphansi kanye nesikhathi esincishisiwe sokungasebenzi. Kunoma yimuphi umqhubi obhekene nezimo zokubhoboza ezishisa kakhulu e-Oman, i-Ninestones ukuphela kwesinqumo sabasiki be-PDC abahlala isikhathi eside, abazinzile ngokokushisa ongabethemba ukuthi bazokwenza lapho kubaluleke kakhulu."
