Ubuciko obuhleliwe: Ukwembulela izimfanelo ezivelele zezingcezu ze-PDC ezisezingeni eliphakeme

1. Isakhiwo esiqinile futhi esisebenza kahle

①　Ama-blades anamandla aphezulu: ama-blade kumele enziwe ngamandla aphezulu, ama-matrix aqinile aphezulu noma izinto zensimbi, ezikwazi ukubekezelela imithwalo yomthelela we-torhole phansi kanye namabutho ama-toryional. Lokhu kuqinisekisa ukuthi i-drill bit ihlala iqinile ekwakhekeni okuyinkimbinkimbi ngaphandle kokuqhekeka noma ukugqoka ngokweqile, okwenza kube lulaIzingcezu zokumba izimayinina-Ama-rock drill bitsezindaweni ezinokhahlo.

②　Ukuvikelwa okuqondile kwe-Gauge: Idizayini ye- "Gauge Pads" kanye "nama-Crown Chamfers" athinta ngqo ikhwalithi ye-Wellbore. Ama-Gauge Pads adinga ukugqokwa kakhulu ukuze alondoloze ngempumelelo ububanzi be-drill bit futhi avikele i-wandergauge, ebaluleke kakhulu ebhilisweni elingu-core drill kanye ne-PDC core drill bits. Umqhele we-Crown Conmfer osebenzayo usiza amafomu angena kahle angenele kanye nokuqondisa ukuqondisa, ukuthuthukisa ukuqina ekuvuthweni okuncane 8 1/2 kanye namanye amasayizi ajwayelekile.

I-Rickmore yamukela i-matrix eyinhlanganisela eqinisiwe ye-gradient-composite, eyenzelwe ukusatshalaliswa kwengcindezi ngokuhlaziywa kwe-Fination. Ngamandla e-shear≥I-800MPA kanye nomthelela onamandla≥25J/cm², ibekezelela ukushintshana kwemithwalo ezinqubeni eziyinkimbinkimbi, iqinisekisa ubuqotho bezinhlekelele ekwakhekeni okuhlangene kakhulu futhi okunzima kokuhlangene, kanye nokugcina isivinini sokumba esizinzile—IlungeleAma-PDC oyili wokumba kahle kahle.

①　Amazinyo wokusika ebangeni eliphezulu—Ama-PDC cutters. Ikhwalithi ephezuluAma-PDC BitsKufanele usebenzise ama-PDC ama-PDC ama-PDC anokuqina okuphezulu okushisayo, ukumelana kokugqoka ngokweqile, nokumelana kahle nomthelela omuhle kakhulu. Lesi isiqinisekiso esiyisisekelo sempilo ende ende nesivinini esikhulu sokumba, sinomthelela ngqo kwentengo ye-PDC Cutter Drill Bit Bit kanye nokusebenza okuphelele.

②　Ukuhlelwa kwamazinyo okuqondile: ukuhlelwa kwamazinyo okusika ibala (density, angle, ukuphakama kwe-protrusion) kudinga ukubalwa okuqondile kwe-hydraulic kanye ne-mehendi. Ukuhlelwa kwamazinyo okunengqondo kukhulisa ukusebenza kahle kwe-rock, ukulinganisa ulaka nokuqina, futhi kukhulisa ukupholisa amazinyo okusika—egxeka i-PDCBill kancaneNgedwala kanye ne-4 inch PDC drill bits.

I-Rickmore ikhetha i-diamond ephezulu yedayimane encane ngosayizi we-5-10μm, wenkohliso ekushiseni okuphezulu nengcindezi (≥1400℃, ≥5.5gPA). Amandla okuhlanganisa okuhlanganisa okuhlanganisa i-bonding ungqimba≥I-350mpa, kanye nokumelana nokugqoka (isilinganiso sokugqoka esihlobene)≥120,000. Kuhlanganisa ukumelana nomthelela kanye nokuvimbela ukumelana, ukunciphisa ngempumelelo ingozi yokujaha izinyo nokuwa—Ukhiye we-225mm PDC Drill Bits nokunye ukucaciswa.

3. Kwenzelwe uhlelo lwe-hydraulic lwe-hydraulic: i-lifeline yokuhlanza nokupholisa

①　Ama-nozzles asebenza kahle: "Ama-nozzles amelana ne-cororion" asemqoka. Ama-nozzles kumele enziwe ngezinto ezingamelana nokungamelana nokugula ezivinjelwe njenge-carbide enesihlahla. Idizayini yabo yesiteshi sokugeleza sangaphakathi ilungiselelwe ukwakha ama-jets asheshe, inomthelela ovumayo umgodi ongezansi nezimpande ze-blade. Lokhu kuhlanza ngempumelelo ukusika amazinyo, kupholisa kancane, futhi kusiza ekuqhekekeni kwe-rock. Ukuphikiswa kokugqwala kuqinisekisa ukusebenza okuzinzile kumanzi ayinkimbinkimbi aqukethe i-hydrogen sulfide, okufaneleImishini yokushayela amanzina-Ukushayela kahle.

②　I-Flow Channel Design: Isakhiwo kanye ne-angle yama-nozzles kufanele ahambisane kahle nama-blades kanye nama-junk slots ukwakha i-drive flow flow flow. Lokhu kugwema ama-eddy currents noma izindawo ezifile, ukuqinisekisa ukusika kususwe ngokushesha—Ukuthuthukisa ukusebenza kahle kwe-PDC Drill Bit Diamond kanye ne-PDC Diamond Drilling Systems.

I-Rickmore Ihlele i-nozzle layout kanye ne-flow Channel Curvature esekelwe kubuchwepheshe be-CFD Flow Field Simulation Simulation Technology, okwandayo ukusikwa okushisayo kwejubane lokuhamba ngejubane elingaphezu kwama-30% nokusikwa okuthi kusebenza kahle≥95%. Lokhu kunciphisa kakhulu ukusika izinyo ukugqokwa kokugaya kwesibili kwama-cuttings futhi kwehlise amathuba okuthola ukukala okuncane, i-boon forUkushayela BitsEmishini emishini enyakazayo yomhlaba kanye nemishini yokwakha izingxenye zezingxenye.

4. Ukuxhumeka okuthembekile nokuqinile nemininingwane eqinile: Isiqinisekiso sokuhlinzwa isikhathi eside

①　Amalunga aqinile: "Ukuxhumana kwe-API"—Ukuxhumana okuhlanganisiwe komhlangano we-API—Isisekelo sokuxhuma okuphephile nokuthembekile phakathi kwezinduku zokumba nokumba. Kumele banembe ngokuluci ngamandla anele okugwema ukunqanyulwa phansi kwemvula, okubucayi kokuqinisekisa ubuqotho bezinhlelo zokumba emishini yokumba kahle kanye nogandaganda ama-mini 4x4-okubanjiwe.

②　Idizayini engavikeli umthelela: "Slots Breaker" (ama-grooves avimbela umthelela) ajwayele ukwakhelwa empandeni yama-blades ensimbi, amunca ngempumelelo futhi ehlakaze ukwehla kwe-Downhole nemithwalo yomthelela. Lokhu kuvikela ama-blades kanye nokusika amazinyo, ukunweba impilo yenkonzo ye-PDC Drill Bits futhi kunciphise izindleko zokusebenza ezihlobene nentengo ye-PDC.

I-Rickmore isebenzisa i-API Standard Simplency Fight Right Design, ngokunemba kwentambo kufinyelela ku-4H / 5g kanye nokuvuka kwe-rating surface roughness≤Ra1.6μm, ukuqinisekisa ukusebenza kahle kokuhambisa i-torque≥98%. Izingxenye ezibalulekile zokubekwa uphawu zisebenzisa izakhiwo zensimbi ezihlanganisiwe zensimbi, ngokumelana nengcindezelo≥I-35MPA, iqinisekisa ukuhambisana nokuthembela okuphezulu okuhambisana nohlelo lwe-Drill String—Iyahambisana neyehlukeneUkushayela Bitskanye nokuvutha induku.
