Sarudza iyo Right PDC Cutter, Drill Smarter & Nekukurumidza

Mukuchera mafuta, kuita kwePDC zvikamuinovimba zvachose nePDC cutters (Polycrystalline Diamond Compact), iyo inotarisisa zvakananga kudhirowa uye hupenyu hushoma. Kiyi pakusarudza iwo maPDC cutters akanyatso kuenderana nemaitiro ekugadzira: mafomati akapfava anoisa pamberi pekushanda zvakanaka, maumbirwo akaomarara anotungamira kusimba, uye maumbirwo akaomarara anotungamira kuchinjika. Kusarudzwa kwakashata kunomhanyisa kupfeka kwekucheka, kunowedzera kudyiwa, kunonotsa kufambira mberi kwekuchera zvakanyanya, uye kunokwidza mitengo yekushandisa. 

Inoratidzira dhizaini-chaiyo dhizaini pane yayo musimboti, DrillMorePDC zvikamugadzirisa zvakakwana kusarudzwa uye kuita zvinonetsa pamamiriro ese ekuchera, zvichiita kuti ive sarudzo yakasarudzika yevadhiraivha pasi rese. 

Kune maumbirwo akapfava (dhaka, dombo rejecha risina kusanganiswa) uko kunonyanya kukosha kwakakosha, DrillMore inoshandisa hombe 16-19mm inochekwa yakatarisana. Sintered kubva pamhando yepamusoro 5–10μm diamond poda pasi pekupisa kwakanyanya uye kudzvanywa kwakanyanya, aya makucheka ane mipendero yakapinza uye yakaderera cutter density. Yakasanganiswa neCFD-yakagadziridzwa mvura makosi, ivo vanowana yakakwira kupinza mitengo, inobudirira chip kubviswa, uye yakanakisa anti-kubhowa kuita, kuzadzisa zvizere zvinodikanwa zvekuchera-maumbirwo ekuchera. 

Kune maumbirwo epakati-akaoma (sandstone yakasimba, limestone), DrillMore inotora nzira yakadzikama ine 14.5-16mm yakajairwa kucheka. Gradient-yakasimbiswa composite matrix zvinhu zvinoburitsa kupfeka kuramba uye kukanganisa kupikisa, ine cutter density yakagadziridzwa kuburikidza nechaiyo hydraulic simulation. Izvi zvinoyera kushanda zvakanaka uye hupenyu hwesevhisi zvichipesana neakapfava abrasive mafomati, achiratidza kugadzikana kwakatanhamara uye mutengo-kushanda muminda yakadai seJiyang Depression uye Ordos Basin. 

Kune akaomesesa uye akanyanya abrasive maumbirwo (quartz sandstone, chert), DrillMore's premium high-thermal-stability PDC bits ndiyo yakakwana mhinduro. Yakashongedzerwa nediki 13-14.5mm maumbirwo ekucheka (chisel, sengowani-yakaita), iwo akatsetseka-zviyo madhaimani layers anopa kusakara (relative wear ratio ≥ 120000) zviri pamusoro pemaindasitiri zviyero. Yakakwira-density cutter dhizaini uye FEA-yakagadziridzwa kudzvanya kugovera inodzivirira yakanyanya abrasion, tembiricha yakakwira, uye kukanganisa, kudzivirira kupera nguva isati yakwana kana kucheka uye kuwedzera zvakanyanya hupenyu hwesevhisi. 

Kune akaomesesa maumbirwo (akaomesesa interbed, gravel layers, yakakwirira H₂S nharaunda), DrillMore's yakakosha inopesana-inopikisa PDC bits vanoita-kutenderera. Ivo vanotora akasanganiswa ekucheka maumbirwo uye yakadzama dhizaini yevadiki uye epakati-saizi vanocheka: akafuratira anocheka anochengetedza kushanda zvakanaka, nepo akaumbwa anocheka anoshingirira. Yakabatanidzwa nemazino asingadziviriri uye simbi-rabha inoumbwa zvisimbiso, inoshivirira H₂S-inotakura zvinwiwa. Mumashandisirwo akaomarara akadai seyepamusoro-sarufa subsalt reservoirs uye coalbed methane horizontal matsime muOrdos Basin, zvinobudirira kudzivirira kutyora kwekucheka uye kunamatira, kuve nechokwadi chekuchera kwakachengeteka uye kwakanaka. 

Iko hakuna universal PDC cutter, asi DrillMorePDC zvikamununura ** yakazara kuumbwa kuchinjika **! 

Kubva pakuumbwa kwakapfava kusvika kunzvimbo dzakaomarara dzesarufa, kubva kumatsime akatwasuka kusvika kumatsime akachinjika, modhi yega yega yakanyatso kugadzirwa mamiriro ekuumbwa. API-yakajairwa tambo inovimbisa inoshanda uye yakagadzikana torque kutapurirana. Imwe neimwe diki inowana indasitiri-inotungamira nhanho uye mwero wekupinda (ROP), ine-inomhanya-inomhanyisa budiriro yekuchera mumatsime akawanda munyika yose, kupfupisa zvakanyanya kutenderera kwekuchera uye kuderedza mitengo yekushandisa. 

Sarudza DrillMore yekuchera inoshanda, yakavimbika, uye inodhura nguva dzese!
