Iyini i-PDC Bit?
Uma usembonini kawoyela negesi, cishe ujwayelene negama elithi "i-PDC drill bit." Kodwa kulabo abashaIzingxenye zokugaya ze-PDC , ukuqonda ukuthi iyini i-PDC drill bit kanye nokubaluleka kwayo emisebenzini yokumba kungase kudideke kancane. Kulokhu okuthunyelwe kwebhulogi, sizosusa i-demystify theIdatha ye-PDCfuthi uchaze konke odinga ukukwazi mayelana nalokhu okubucayiithuluzi lokubhoboza.
Okokuqala, i-PDC imele i-Polycrystalline Diamond Compact. Izingcezu zokubhoboza ze-PDC ziwuhlobo lwe-drill bit olusetshenziswa kakhulu embonini kawoyela negesi ukubhoboza izinhlobo ezahlukahlukene zamatshe. Ngokungafani nezingcezu ze-roller cone drill zendabuko ezisebenzisa amazinyo ensimbi ukuphula idwala,Izingxenye zokugaya ze-PDC babe nezisiki zedayimane zokwenziwa ezishumekwe ekhanda. Laba basiki bedayimane baqine ngokwedlulele futhi bangakwazi ukubhoboza ngendlela eqinile, benze izingcezu zokubhola ze-PDC zibe enye yezinketho zokuqala zokumba imisebenzi.
Enye yezinzuzo eziyinhloko ze-PDC drill bits ukuqina kwazo. Iamathuluzi okusika idayimane ekhanda lokubhoboza lingamelana namazinga okushisa aphezulu kanye nezimo ezilimazayo, ezivumela ukuthi zigcine amakhono okusika ngokuhamba kwesikhathi. Lokhu kusho ukuthi izingcezu ze-PDC zibhola ngokushesha futhi zihlala isikhathi eside kunezingcezu zekhoni ye-roller evamile, ekugcineni konga izindleko zokusebenza zokumba.
Ngaphezu kokuqina, izingcezu zokubhola ze-PDC nazo zithuthukisa ukusebenza kahle kokumba. Idizayini ye-PDC drill bit ivumela ukudluliswa kwamandla okuqondile kakhudlwana ukusuka emshinini wokubhoboza ukuya ebhithi lokubhoboza, okuholela ekubholani okusheshayo, okusebenza kahle kakhudlwana. Lokhu kuwusizo ikakhulukazi lapho ubhoboza amatshe aqinile, lapho kungaba nzima khona ukuthi izinsimbi zokubhola ezivamile zithuthuke.
Esinye isici esibalulekile se-PDC drill bits yikhono lazo lokuhlinzeka ngamazinga aphezulu okungena (ROP). Izisiki zedayimane ezibukhali ezisekhanda lokubhola zinika amandla isivinini sokumba ngokushesha, okuvumela opharetha ukuthi baqedele imisebenzi yokumba ngesikhathi esincane. Lokhu akusizi kuphela ukwehlisa izindleko zokusebenza, futhi kunciphisa ukuguga nokudilika kwemishini yokumba, ekugcineni kunwebe impilo ye-rig kanye nezingxenye ezihambisanayo.
Kubalulekile ukuqaphela ukuthi ngenkathi i-PDC drill bits inikeza izinzuzo eziningi, ayinayo imikhawulo. Izingcezu zokubhoboza ze-PDC zingaba nobunzima bokubhoboza ngendlela ethile, njengetshe lesandstone eliqhumayo noma lezo ezinokuqukethwe kwe-chert ephezulu. Kulezi zimo, ezinye izingcezu zokubhoboza zingadinga ukucatshangelwa ukuze kuqinisekiswe ukusebenza kahle nokuyimpumelelo kokumba.
Kafushane, izinsimbi zokubhola ze-PDC zingamathuluzi abalulekile embonini kawoyela negesi, enikeza ukuqina, ukusebenza kahle kanye nokusebenza okuthuthukisiwe kokumba. Ngokuqonda amandla kanye nemikhawulo ye-PDC drill bits, opharetha bangenza izinqumo ezinolwazi lapho bekhetha ithuluzi lokumba elifanele lomsebenzi wabo. Njengoba ubuchwepheshe buqhubeka buthuthuka, silindele ukuthi ukwakheka nokusebenza kwezingcezu zokumba ze-PDC kuzothuthukiswa nakakhulu, kuthuthukiswe indima yazo enqubweni yokumba.
