Okokuqala, ukubhola kwedayimane ngaphambi kokulungiselela ukumba
1. Hlola ukuthi ingabe ukhona yini umonakalo emzimbeni wokugcina webhithi ledayimane, ukulahleka kwamazinyo, njll., ukuze uqinisekise ukuthi ingaphansi lomthombo lihlanzekile futhi azikho izinto eziwayo.
2. Phatha ibhithi ledayimane ngokucophelela bese ubeka ingxenye yedayimane phezu kwephedi yenjoloba noma ukhuni.Ungabeki ibhithi ledayimane ngqo epuleti lensimbi.
3, hlola ukuthi ingabe ukhona yini umonakalo kumsiki webhithi yedayimane, ukuthi kukhona yini umzimba wangaphandle kubhithi yedayimane, ukuthi kukhona yini indandatho yokuvala yohlobo lwe-o embotsheni ye-nozzle, ngokwesidingo sokufaka umlomo wombhobho.
ezimbili Ibhithi ledayimane liyaqhuma
1. Hlanza ibhande ledayimane leduna noma lensikazi bese ugcoba amafutha kasilika.
2. Bopha iketango engxenyeni yedayimane bese wehlisa intambo yokubhoboza ukuze ixhumane nebhande lesilisa noma lesifazane.
3. Hlanganisa ibhithi ledayimane ne-shackler phakathi nendawo yetafula elijikelezayo, bese ugoqa isikulufu ngokwenani letorque elinconyiwe lebhande.
3. Geza phansi
1. Gijimisa kancane idayimane, ikakhulukazi ngetafula elijikelezayo, i-BLOWout preventer, ne-casing hanger, ukuze uvikele umsiki.
2. Naka ingxenye yomthombo ovimbekile ohambweni lokugcina lokumba.Ngesikhathi sokumba, i-bit kufanele idlule kancane lapho ububanzi buncishisiwe.
3. Uma isiqhele ngocezu olu-1 phansi komthombo, iqala ukujikeleza ngesilinganiso sokumba esingu-50~60rpm bese ivula iphampu elinganiselwe yokugudluza ukuze ishaye phansi phansi komthombo.
4. Qaphela inkomba yesisindo kanye ne-torque ukwenza ibhithi ledayimane lithinte phansi kahle.
Ezine.Ukubhoboza nge-diamond bit
1. Akunconywa ukusebenzisa izingcezu zedayimane ukuze kulungiswe kabusha isigaba.
2. Uma kunesidingo, ukufuduka okulinganiselwe kanye ne-torque ephansi kufanele kusetshenziswe.
Ezinhlanu.Ukubumba ibhithi ledayimane
1. Gcina ukugudluka okukaliwe bese wehlisela ibhithi ledayimane phansi komthombo.
2. Bamba kancane okungenani i-1m ukuze uthole imodeli yembobo engezansi.
3. Khulisa i-bit pressure ibe yinani elingcono kakhulu lokumba okuvamile ngokunyuka ngo-10kN isikhathi ngasinye.Ukucindezela okweqile kunqatshelwe ngokuphelele ukubangela ukulimala kwangaphambi kwesikhathi kwebhithi ledayimane.
4. Lungisa i-roP ngokugcina isisindo esincane esingashintshi ukuze uthole inhlanganisela engcono kakhulu yamapharamitha wokumba.
Eziyisithupha.I-diamond bit drilling evamile
1. Uma uhlangabezana nesihlabathi esinamaqabunga noma esiqinile netshe lodaka, yehlisa izinga lokumba ukuze welule impilo yebhithi ledayimane.
2. Lungisa i-roP nebhithi yedayimane ukuze ulondoloze ukusebenza kahle kokumba lapho uhlangabezana nezinguquko zokwakheka noma ukuphambana kwemigwaqo.
3, isikhathi ngasinye impande eyodwa iphawula amaphuzu alandelayo:
3.1 Buyisela inombolo yokushaywa kwepompo bese uhlola umfutho wesikhuphukeli.
3.2 Vula iphampu ngaphambi kokuba ibhithi ledayimane lithinte phansi embobeni, bese wehlisa kancane kancane idayimane liye phansi embobeni ngesilinganiso sokubhola esingu-50-60rpm.
3.3 Buyisela kancane kancane ingcindezi kubhithi yedayimane yangempela bese ukhuphula i-ROP ibe yi-ROP yasekuqaleni.
Ukusebenza kwenkundla kufakazele ukuthi ucezu lwedayimane lunobuhle bejubane elisheshayo, ividiyo eyengeziwe, impilo ende, ukusebenza okuzinzile, izingozi ezincane ezingaphansi komhlaba kanye nezinga elihle lomthombo lapho ubhoboza esigabeni esiqinile esithambile nesimaphakathi.Izingcezu zedayimane azihlali nje isikhathi eside, kodwa futhi zingasetshenziswa kabusha.Ukubuyisela izingcezu zedayimane ukuze zilungiswe kungasindisa kakhulu izindleko zokumba.
Isikhathi sokuthumela: Dec-27-2021
