Khetha I-PDC Cutter Elungile, Drill Smarter & Ngokushesha

Ekubholeni amafutha, ukusebenza kweIdatha ye-PDCithembele ngokuphelele kubasiki be-PDC (i-Polycrystalline Diamond Compact), enquma ngokuqondile ukusebenza kahle kokubhola nokuphila kancane. Isihluthulelo sokukhetha abasiki be-PDC abalungile ukufanisa okunembile nezici zokubunjwa: ukwakheka okuthambile kubeka phambili ukusebenza kahle, ukwakheka okuqinile kubeka phambili ukuqina, futhi ukwakheka okuyinkimbinkimbi kubeka phambili ukuguquguquka. Ukukhetha okungafanele kusheshisa ukuguga, kukhulisa ukusetshenziswa kancane, kubambezele inqubekelaphambili yokumba kakhulu, futhi kunyusa izindleko zokusebenza. 

Ifaka phakathi ukwakheka okuqondile okuyisisekelo sayo, i-DrillMoreIdatha ye-PDCukuxazulula ngokuphelele izinselele zokukhetha nokusebenza kuzo zonke izimo zokumba, ukwenze kube ukukhetha okuncanyelwayo kwababhola emhlabeni jikelele. 

Ngokwakheka okuthambile(itshe lodaka, isihlabathi esingahlanganisiwe) lapho ukusebenza kahle okuphezulu kubaluleke kakhulu, i-DrillMore isebenzisa izisiki ezinkulu ezinobuso obuyisicaba obungu-16–19mm. I-Sintered kusuka kumpushana wedayimane wekhwalithi ephezulu ongu-5–10μm ngaphansi kwezinga lokushisa eliphezulu nokucindezela okuphezulu, laba basiki banemiphetho ebukhali kanye nokuminyana okuphansi komsiki. Kuhlanganiswe nezifundo zoketshezi ezilungiselelwe i-CFD, zithola amazinga aphezulu okungena, ukukhishwa kwe-chip okuphumelelayo, nokusebenza okuhle kakhulu kokumelana nokubhola, ukuhlangabezana ngokugcwele nezidingo zokubhola kokwakheka okuthambile. 

Ngokwakheka okuqinile okumaphakathi (itshe lesanti eliqinile, i-limestone), i-DrillMore ithatha indlela elinganiselayo nabasiki abajwayelekile abangu-14.5–16mm. Izinto ze-matrix eziqiniswe nge-Gradient ziletha ukumelana nokuguga kanye nokumelana nomthelela, ngobuningi be-cutter obuthuthukiswa ngokulingisa okunemba kwe-hydraulic. Lokhu kulinganisa ukusebenza kahle kokusika kanye nempilo yesevisi ngokumelene nezakhiwo ezilumayo ezincane, okubonisa ukuzinza okuvelele kanye nokusebenza kahle kwezindleko emikhakheni efana ne-Jiyang Depression kanye ne-Ordos Basin. 

Ngokwakheka okuqinile nokuqina kakhulu (itshe le-quartz sandstone, i-chert), amabhithi e-PDC asezingeni eliphezulu e-DrillMore's premium-thermal-stability ayisixazululo esilungile. Zihlonyiswe ngezisiki ezincane ezinomumo ongu-13–14.5mm (ishizolo, okumise okwesigqoko), izendlalelo zazo zedayimane ezisanhlamvu ezinhle zinikeza ukumelana nokugqoka (isilinganiso sokugqoka okuhlobene ≥ 120000) ngaphezu kwezindinganiso zomkhakha. Isakhiwo se-high-density cutter kanye nokusabalalisa ingcindezi okwenziwe nge-FEA ukumelana nokuhuzuka okukhulu, amazinga okushisa aphezulu, nomthelela, ukuvimbela ukuguga ngaphambi kwesikhathi noma ukucwiliswa kanye nokwelula kakhulu impilo yesevisi. 

Ngokwakheka okuyinkimbinkimbi (ama-hard interbed, izendlalelo zamatshe, izindawo eziphakeme ze-H₂S), amabhithi e-PDC amelana nomthelela okhethekile we-DrillMore angabadlali abajikelezayo. Basebenzisa amajamo okusika okuxubile kanye nesakhiwo esintengayo sabasiki abancane nabaphakathi nendawo: abasiki abayisicaba bagcina ukusebenza kahle, kuyilapho abasiki abanomumo bemelana nomthelela. Uma ubhangqwe namabhomu angagqwali kanye nezigxivizo eziyinhlanganisela yerabha yensimbi, abekezelela uketshezi oluthwala i-H₂S. Ezisetshenziswa eziyinkimbinkimbi ezifana nemithombo ye-subsalt enesulfure ephezulu kanye nemithombo evundlile ye-methane yamalahle e-Ordos Basin, ivimbela ngempumelelo ukuphuka nokunamathela komsiki, ukuqinisekisa ukubhola okuphephile nokusebenza kahle. 

Ayikho i-PDC cutter yendawo yonke, kodwa i-DrillMoreIdatha ye-PDCukuletha **ukuvumelana nezimo kokwakheka okuphelele**! 

Kusukela ekubunjweni okuthambile kuya ezindaweni eziyinkimbinkimbi ezinesulfure ephezulu, ukusuka emithonjeni eqondile ukuya emithonjeni evundlile, yonke imodeli iklanyelwe ngokunembile izimo zokubunjwa. Izintambo ezijwayelekile ze-API ziqinisekisa ukudluliswa kwetorque okusebenzayo nokuzinzile. Ibhithi ngalinye lizuza amavidiyo ahamba phambili embonini kanye nezinga lokungena (i-ROP), okuyimpumelelo yokumba eyodwa emithonjeni eminingi ezweni lonke, okufinyeza kakhulu imijikelezo yokumba kanye nokunciphisa izindleko zokusebenza. 

Khetha i-DrillMore ukuze uthole ukubhola okusebenzayo, okuthembekile, futhi okungabizi ngaso sonke isikhathi!
