Khetha PDC Cutter e nepahetseng, Drill Smarter & Faster

Ho cheka oli, ts'ebetso eaLikotoana tsa PDCe itšetlehile ka ho feletseng ho li-cutters tsa PDC (Polycrystalline Diamond Compact), tse khethollang ka ho toba katleho ea ho cheka le bophelo bo fokolang. Senotlolo sa ho khetha li-cutters tse nepahetseng tsa PDC ke ho tsamaisana hantle le litšobotsi tsa sebopeho: libopeho tse bonolo li etelletsa pele katleho, libopeho tse thata li etelletsa pele ho tšoarella, 'me libopeho tse rarahaneng li etelletsa pele ho ikamahanya le maemo. Khetho e sa nepahalang e potlakisa ho roala ha li-cutter, e eketsa tšebeliso e nyane, e liehisa tsoelo-pele ea ho cheka haholo, 'me e phahamisa litšenyehelo tsa ts'ebetso. 

E fana ka sebopeho se ikhethileng molemong oa eona, DrillMoreLikotoana tsa PDCrarolla ka mokhoa o phethahetseng liphephetso tsa khetho le ts'ebetso maemong ohle a ho cheka, ho etsa hore e be khetho e ratoang ke ba cheka lefatšeng ka bophara. 

Bakeng sa libopeho tse bonolo (lejoe la seretse, lejoe la lehlabathe le sa kopanngoeng) moo ts'ebetso e phahameng e leng bohlokoa, DrillMore e sebelisa liseha tse nang le sefahleho se sephara sa 16-19mm. Sintered ho tloha boleng bo phahameng ba 5-10μm phofo ea daemane tlas'a mocheso o phahameng le khatello e phahameng, li-cutters tsena li na le mathōko a bohale le li-cutter tse tlaase. Ha li kopantsoe le lithupelo tsa mokelikeli o ntlafalitsoeng oa CFD, li fihlella litekanyetso tse phahameng tsa ho kenella, ho tlosoa ha li-chip tse sebetsang hantle, le ts'ebetso e ntle ea anti-ball, ho fihlela litlhoko tsa ho cheka ka mokhoa o bonolo. 

Bakeng sa libopeho tse thata tse mahareng (lejoe la lehlabathe le tiileng, limestone), DrillMore e nka mokhoa o leka-lekaneng le li-cutters tse tloaelehileng tsa 14.5-16mm. Lisebelisoa tsa matrix tse matlafalitsoeng ke gradient li fana ka khanyetso le ts'usumetso, ka sekhahla sa "cutter" se ntlafalitsoeng ka papiso e nepahetseng ea hydraulic. Sena se leka-lekanya katleho le bophelo ba ts'ebeletso khahlano le mekhoa e mebe, e bonts'a botsitso bo ikhethang le ho baballa litšenyehelo mafapheng a kang Jiyang Depression le Ordos Basin. 

Bakeng sa libopeho tse thata le tse senyang haholo (quartz sandstone, chert), DrillMore's premium high-thermal-stability PDC bits ke tharollo e nepahetseng. E na le li-cutters tse nyane tsa 13-14.5mm (chisel, sebopeho sa helmete), likarolo tsa tsona tsa daemane tsa lijo-thollo tse ntle li fana ka khanyetso ea ho roala (karolelano ea moaparo o amanang ≥ 120000) kaholimo ho maemo a indasteri. Sebopeho sa "high-density cutter" le phetisetso ea khatello ea maikutlo e ntlafalitsoeng ke FEA e hanela ho soahlamana ho matla, mocheso o phahameng le tšusumetso, e thibela ho roala pele ho nako kapa ho putlama le ho lelefatsa bophelo ba ts'ebeletso haholo. 

Bakeng sa libopeho tse rarahaneng (li-interbed tse thata, likarolo tsa lehlohlojane, libaka tse phahameng tsa H₂S), li-PDC tse hanyetsanang le tšusumetso e khethehileng ea DrillMore ke libapali tse pota-potileng. Li nka libopeho tse tsoakiloeng tsa li-cutter le moralo o tsitsitseng oa li-cutters tse nyane le tse mahareng: li-cutters tse bataletseng li boloka ts'ebetso, athe li-cutters tse nang le sebopeho li mamella tšusumetso. Li kopantsoe le li-nozzles tse sa jeng le litiiso tse entsoeng ka rabara ea tšepe, li mamella maro a nang le H₂S. Lits'ebetsong tse rarahaneng tse kang matamo a letsoai a phahameng a sebabole le liliba tse otlolohileng tsa methane tse ka har'a Ordos Basin, li thibela ka katleho ho robeha le ho khomarela, ho netefatsa hore ho cheka ho bolokehile le ho sebetsa hantle. 

Ha ho na sehahi sa PDC sa bokahohleng, empa DrillMoreLikotoana tsa PDCfana ka **mahalo a sebopeho se felletseng **! 

Ho tloha ho libopeho tse bonolo ho ea ho tse rarahaneng tse nang le sebabole se phahameng, ho tloha lilibeng tse otlolohileng ho ea lilibeng tse tšekaletseng, mohlala o mong le o mong o entsoe ka nepo bakeng sa maemo a sebopeho. Likhoele tse tloaelehileng tsa API li netefatsa phetiso ea torque e sebetsang hantle le e tsitsitseng.
