Kunzwisisa Tekinoroji Kuseri kwePDC Bits
1) Zvimiro zvePDC drill bits
PDC drill bits anoumbwa ne drill bit body, PDC yekucheka mazino uye nozzles. Iwo akakamurwa kuita maviri akateedzana: muviri wesimbi uye matrix muviri zvinoenderana neakasiyana zvimiro uye maitiro ekugadzira. Iyo yese bhiti muviri weakaomesesa PDC drill bit inogadzirwa nepakati kabhoni simbi uye inogadziriswa uchishandisa mechanic kugadzira maitiro. Dhobora maburi panzvimbo yekushanda yedhiri uye sunga mazino ekucheka PDC kukorona yebhiti rekubooresa nepress fit. Iyo korona yekuchera inobatwa nekuomesera kwepasi (spraying tungsten carbide wear-resistant layer, carburizing, etc.) kuti iwedzere kuomarara kwayo. Kubatsira kukuru kweiyi drill bit ndeyekuti nzira yekugadzira iri nyore; iyo yakashata ndeyokuti chibooreso chemuviri hachigadziriswi nekukukurwa uye mazino ekucheka akaoma kuchengetedza, saka ikozvino haawanzoshandiswa. Chikamu chepamusoro chemuviri wekuboora matrix PDC drill bit isimbi, uye chikamu chezasi ndeye tungsten carbide wear-resistant alloy matrix, inogadzirwa nekuumbwa uchishandisa poda metallurgy sintering process. Shandisa pasi-tembiricha solder weld iyo PDC yekucheka mazino kune yakachengetwa grooves muchitunha. Iyo tungsten carbide matrix ine kuomarara kwakanyanya uye inoshingirira mukukukurwa. Naizvozvo, iyo matrix PDC drill bit ine hupenyu hurefu uye yakakwirira tsoka, uye parizvino inoshandiswa zvakanyanya.
2) Kushanda musimboti wePDC drill bit
PDC drill bits inopwanya matombo nekucheka. Mazino ekucheka ega-anozvicheka anogona kucheka nyore nyore mukugadzirwa pasi pechiito chekudhiraivha, uye kuenderera mberi kunogera dombo pasi pechiito che torque. Multiple PDC yekucheka mazino anoshanda panguva imwe chete, uye dombo riri pazasi petsime rine nzvimbo dzakawanda dzemahara, uye dombo rinotsemuka nyore pasi peshear, saka dombo rekupwanya kushanda kwakakwira uye kukurumidza kwekuchera kunokurumidza.
3) Kushandiswa kwakarurama kwePDC bits
PDC drill bits inoshanda zvakanyanya muzvikamu zvakakura zvehomogeneous soft to medium-hard formations. Haina kukodzera kuchera matombo ematombo uye yakapfava uye yakaoma strata. Uchishandisa yakaderera kudhiraivha kudzvanywa, kumhanya kwakakwira uye kudhiraivha kwakakura, iyo drill bit ine mhedzisiro yakanaka.
Chibooreso chisati chapinda mugomba, pasi pegomba panofanira kunge pakachena kuti ive nechokwadi chekuti hapana simbi inodonha.
Kana chibooreso chikatanga kudzikiswa mugomba, kadhibhiro kadiki kekuchera uye kukurumidza kutenderera kwakaderera kunofanira kushandiswa kumhanyisa bhiti, uye kuchera kwakajairika kunofanira kutangwazve mushure mekunge pasi pegomba raumbwa. Iyo PDC drill bit idhiri rakakosha risina chero nhengo dzinofamba uye inokodzera kuchera-kumhanya kweturbine.
Pakusarudza asimbi muviri PDC drill bits, pane zvakati wandei zvekufunga nezvazvo kuti ive nechokwadi chekuita kwakanyanya. Chekutanga, zvakakosha kuongorora mamiriro ekuchera chaiwo uye maitiro ekuumba kuti uone zvakakodzera dhizaini dhizaini uye zvakatemwa. Zvinhu zvakadai semhando yekugadzira, kudzika kwekuchera uye inodiwa yekumhanyisa kumhanya kunopesvedzera kusarudzwa kweiyo yakakodzera simbi muviri PDC drill bit yebasa racho.
Pamusoro pezvo, zvakakosha kufunga nezvechigadziriso chemidziyo uye mhando kana uchisarudza simbi-yemuviriPDC drill bits. Kuiswa uye ukuru hwezvishandiso zvekucheka zvinoita basa rakakosha pakuona kucheka kwekuita uye kusimba kwechibooreso. Zvishandiso zvemhando yepamusoro zvekucheka uchishandisa tekinoroji yePDC inogona kuvandudza kushanda kwese uye hupenyu hwesevhisi hwechibhorani, zvichiita kuti ive yakakosha kudyara kumapurojekiti ekuchera kwenguva refu.
Mukuwedzera, dhizaini ye hydraulic function ye drill bit haigoni kuregererwa. Iyo inoshanda hydraulic system yakakosha kuchengetedza zvivakwa zvekucheka zvakachena uye zvinotonhorera, kunyanya mumamiriro ezvinhu akaoma ekuchera. Iyo yakanyatsogadzirwa hydraulic system inobatsira kudzivirira bit pelletizing uye inova nechokwadi Kubudirira kubviswa kwekucheka, kubatsira kuvandudza kudhirowa kuita uye bit hupenyu.
Muchidimbu, nekufunga nezvezvinodiwa zvekuchera uye kusarudza mhando yesimbi-muviri PDC drill bits ine dhizaini chaiyo uye maficha, nyanzvi dzekuchera dzinogona kuwedzera kudhirowa kwehunyanzvi uye kuwana mhedzisiro yepamusoro mukuumbwa kwakaoma.
