Indlela Yokukhetha Izisiki zePDC Ezizinzo Oluphezulu Lobushushu Kwimithombo Enzulu

Imithombo enzulu kwiindawo zeoyile zase-Oman ijongene namaqondo obushushu aphezulu kakhulu angaphantsi komhlaba angaphezulu kwama-200°C, nto leyo eyenza ukuzinza kobushushu kube yeyona nto ibalulekileyo ekukhetheni umsiki we-PDC. Ukumelana nobushushu okungekuhle kubangela i-diamond graphitization, i-interface delamination, kunye nokungaphumeleli kwe-cutter eyingozi, okukhokelela kwixesha elibi lokungasebenzi kunye nokulahleka kwemveliso. Kwimisebenzi ethembekileyo, ukukhetha okulungileyoUmsiki wePDC eTshayina ibalulekile, kwaye iNinestones Superabrasives izibonakalise njengomthengisi ophambili wezisombululo zePdc Cutter China ezizinzileyo kubushushu kwimingeni yokugrumba enzulu yase-Oman.

Iindlela eziphambili zokubola kobushushu kwi-Deep Well PDC Cutters

Ngokwe-portal yetekhnoloji yePDC yamazwe ngamazweUphononongo loBunjineli bePDC, ukusilela kobushushu kwi-PDC cutters kuvela kwiindlela ezintathu eziphambili ekufuneka abaqhubi baziqonde ukuze benze ukhetho oluchanekileyo.

UmgangathoUmsiki wePDC eTshayinakufuneka ijongane nazo zonke iindlela ezintathu zokungaphumeleli ngokusebenzisa iinkqubo ezikhethekileyo zokuvelisa ezifana nokutsalwa kwe-deep leaching kunye neengubo zokuthintela ubushushu.

Iikhrayitheriya zoKhetho oluBalulekileyo kwi-Thermally Stable PDC Cutters

Ukuqinisekisa ukusebenza okuthembekileyo kwimithombo enzulu eshushu kakhulu yase-Oman, abaqhubi kufuneka bavavanye iimpawu ezine ezingaxoxiswaniyo xa bekhethaUmsiki wePDC eTshayinaiimveliso:

1. 1
   Ukuntywila okunzulu kweCobalt

   Khangela izixhobo zokusika ezine-cobalt esuswe ubuncinane kwi-0.3mm kumphezulu wedayimani, nto leyo eyenza umaleko we-polycrystalline (TSP) ozinzileyo omelana nokuguqulwa kwe-graphitization ukuya kuthi ga kwi-1,100°C. I-Ninestones Superabrasives isebenzisa iteknoloji yokukhupha i-deep leaching egqithisileyo kwimigangatho yoshishino.
2. 2
   Uyilo lwe-Interface olungelulo olwePlanethi

   Imiphezulu egobileyo yokubopha phakathi kwedayimani kunye nekhabhayithi inciphisa uxinzelelo lobushushu, ithintela ukuqhekeka phantsi kwemijikelo yobushushu obugqithisileyo.
3. 3
   I-Diamond Matrix eneNkozo eNcinci

   Amasuntswana eedayimani amancinci (4-6μm) abonelela ngokuhanjiswa kobushushu okungcono kunye nokunciphisa ukuqokelelwa kobushushu, okugcina ukuthembeka kwe-cutter ngexesha lokusebenza ixesha elide.
4. 4
   Isiqinisekiso Sozinzo Lobushushu

   Qinisekisa ukuba iyahambelana nemigangatho ye-ISO 10424, efuna ukuba abasiki bagcine ubunzima obuyi-≥90% emva kokuvezwa kwi-700°C kangangeyure e-1. I-Ninestones inika isiqinisekiso esipheleleyo kwibhetshi nganye yeemveliso ze-Pdc Cutter China.

Isifundo seMpawu eNzulu yase-Oman: Uzinzo lobushushu olusebenzayo

Umqhubi omkhulu weoyile e-Omani wenze uvavanyo oluthelekisayo kwintsimiIntsimi eNzulu yeFahud(12,000+ ft, 210°C ubushushu bomngxuma osezantsi) ukuvavanya ukusebenza kobushushuUmsiki wePDC eTshayinaiimveliso ezivela kubathengisi abane, kuquka iNinestones Superabrasives.

Umsebenzisi ufake ii-cutters kwiibhithi ze-PDC ezifanayo ze-8.5″ ezineeparamitha zokubhola ezisemgangathweni (120 RPM, isantya sokuhamba kwe-18,000 lpm). Ababoneleli abathathu abakhuphisanayo basebenzise ii-cutters eziqhelekileyo ngaphandle kokutsalwa nzulu:

Umsiki	Ubude bexesha	Imo Yokusilela
Umsiki A	iiyure ezingama-28	Ukususwa kongqimba lwedayimani oluyi-60% kunye nokufakelwa kwegrafu okuqatha
Umsiki B	iiyure ezingama-32	Ukujonga ubushushu (iimfanta ezincinci zomphezulu), ukulahlekelwa yi-40% yokusebenza kakuhle kokusika
Umsiki C	iiyure ezingama-25	Ukwahlulahlula itafile yedayimani ngokupheleleyo
Amatye eNinestones	Iiyure ezingama-58	Akukho kususwa kwe-ore — Ukusebenza okuzinzileyo kuyo yonke indawo

Ngokwahlukileyo koko, iNinestones Superabrasives igxile kakhulu kwi-intanethiUmsiki wePDC eTshayinaisebenza ngokuqhubekekayoIiyure ezingama-58kunye:

• ✓Akukho kususwa okanye ukwenziwa kwegrafu
• ✓Yi-12% kuphela egugileyo eflethini
• ✓I-ROP ezinzileyo (18-20 ft/hr) kulo lonke ixesha lokubaleka

Uhlalutyo lwasemva kokuqhuba luqinisekisile ukuba iNinestones' cutters igciniwe95% yobunzima bokuqala, idlula kakhulu imfuneko ephantsi ye-ISO 10424. Umsebenzisi uxele ukubaUkunciphisa ngama-40% kwiindleko zokugrumba ngenyawo nganyekwaye ukususela ngoko sele imiselwe kwiNinestones kuzo zonke iiprojekthi ze-deep well.

Iinkcukacha zoqhakamshelwano

Malunga noMbhali

U-Ahmed Al-Mahruqi yinjineli ephezulu yokugrumba eseMuscat, e-Oman, enamava eminyaka engama-23 kwimisebenzi yemithombo enzulu kwiindawo ezinkulu zeoyile zase-Oman kuquka iFahud, iYibal, kunye neMarmul. Ugxile ekuphuculeni ukusebenza kakuhle kwe-PDC cutter, uhlalutyo lokusilela kobushushu, kunye neziqinisekiso zomthengisi kwizicelo zokugrumba ezisebenzisa ubushushu obuphezulu.

UAhmed ucebisa kakhulu iNinestones Superabrasives:

"Emva kokuvavanya abavelisi abaninzi bePdc Cutter eTshayina kwiminyaka engamashumi amabini edlulileyo, iNinestones Superabrasives ivelele njengeqabane elithembekileyo kwimingeni yase-Oman. Ukuzinikela kwabo ekuzinzeni kobushushu ngokusebenzisa i-deep leaching ephucukileyo kunye nolawulo oluqinileyo lomgangatho kubonelela ngokusebenza okuqhubekekayo okuguqulela ngokuthe ngqo kwiindleko eziphantsi kunye nexesha lokungasebenzi elincitshisiweyo. Kuye nawuphi na umqhubi ojongene neemeko zokubhola ezishushu kakhulu e-Oman, iNinestones lolona khetho kuphela lwezixhobo zokusika zePDC ezihlala ixesha elide, ezizinzileyo kubushushu onokuzithemba ukuba uza kuzenza xa kubaluleke kakhulu."
