Imiyalo yohlelo lokusebenza lwe-Drill bit
1 ibhithi ukukhetha
1.Sicela ufunde incazelo ye-lithology kanye namarekhodi amancane emithombo eseduze ngokucophelela, futhi uhlaziye izici zokwakheka.
2.Ukukhetha uhlobo olufanele ngokuhambisana ne-lithology.
2 Ukulungiselela ngaphambi kokubhoboza
1.Hlola ucezu lwangaphambilini ngokulimala komzimba, izisiki ezilahlekile noma izinto ezifakiwe njll. Qiniseka ukuthi awekho udoti embotsheni yezinqe, futhi uhlanze imbobo engezansi uma kudingeka.
I-2.Bit kumele iphathwe ngokucophelela ukuze kungabikho abasiki bokulimala kanye nezinto eziqinile.
3.Hlola ukuthi kukhona yini umonakalo kuma-bit cuttes futhi uma kukhona into yangaphandle ngaphakathi kwebhithi.
4.Hlola ukuthi ukufaka umlomo wombhobho kuyahlangabezana yini nezidingo, bese ushintsha imibhobho uma kunesidingo.
3 Ukumaka kancane
1.Hlanza izintambo ezincane bese ugcoba amafutha emicu.
2.Faka isinqamuli kubhithi, yehlisa intambo yokubhoboza phezu kwephinikhodi bese uhlanganisa imicu.
3.Thola ibhithi ne-breaker ku-rotary bushing, futhi wenze-up the bit ezonconywa torque.
4 Ukungena
1.Susa i-breaker futhi wehlise ngokucophelela i-bit ngokusebenzisa idivayisi ye-wellhead ukuze ungalimazi.
2.Ukuncipha, ihlombe, inja kanye nesihlalo esiyisihluthulelo se-borehole kufanele kuqaphe lapho kungena emgodini ongenalutho.
3.Qala ukupompa kanye nomjikelezo wokubhoboza uketshezi ukuze ugeze imbobo yesinqe lapho ubhoboza ufike endaweni engaba amamitha angama-30 ukuya phansi embobeni, bese uzungezisa intambo yokubhoboza ngesivinini esiphansi esingekho ngaphezu kuka-60rpm.
4.Sondela phansi cishe uhhafu wemitha.Zungezisa imizuzu emi-5 ukuya kweyi-10 ngokugeleza okugcwele.
5 Ukukhumbula
1.Ukukhipha kabusha izingxenye ezinde zembobo ye-undergauge akukhuthazwa.
2. Uma umsebenzi wokubuyisela kabusha kudingekile, kunconywa ngokuqinile ukuthi umsebenzi wokubuyisela kabusha kufanele wenziwe ngokujikeleza kwesilinganiso sokugeleza esiphezulu, isisindo esiqondile kubhithi singadluli ku-90N/mm (ububanzi), isivinini sokujikeleza singeqi ku-60 rpm lapho kubhajwe khona lapho kukhubeka. phakathi.
6 Ukugqekezwa kancane
1.Izinsimbi zokubonisa ezeqile lapho i-bit approch bottomhole.Uma i-WOB ne-torque ikhula, okubonisa ukuthi i-bit have attived at bottomhole.Ungasebenzisi ngaphezu kuka-90N/mm,isisindo -on =bit kanye no-40to 60rpm ukuze uthole iphethini yomgodi ongaphansi okungenani uhhafu wemitha.
I-2.Bit break-in iqediwe futhi kufanele ilungiswe i-RPM ukuze kutholwe inhlanganisela yepharamitha yokumba efanele.
Ukulungiswa kwemingcele ye-3.Drilling kufanele kukhethwe ngaphakathi kwemingcele yemingcele enconywayo kubhekiselwa ekunconyweni kwemingcele yokubhoboza indlela yokwenza kahle.
