1.Hlahloba karolo e fetileng bakeng sa tšenyo ea 'mele, li-cutters tse lahlehileng kapa tse kentsoeng joalo-joalo Etsa bonnete ba hore ha ho na litšila holim'a lesoba la buttom,' me u hloekise lesoba le ka tlase ha ho hlokahala.
2.Bit e tlameha ho sebetsoa ka hloko e le hore e se ke ea senya li-cutters le lintho tse thata.
3.Sheba hore na ho na le tšenyo leha e le efe ho li-bit cuttes le haeba ho na le taba e tsoang linaheng tse ling ka har'a bitana.
4.Sheba haeba ho kenya nozzle ho fihlela litlhoko, 'me u nkele li-nozzle ha ho hlokahala.
3 Ho tšoaea karoloana
1.Clean bit threads 'me u tšele mafura holim'a likhoele.
2.Fit breaker to the bit, theola khoele ea ho phunya holim'a pin 'me u kopanye likhoele.
3.Locate bit and breaker in the rotary bushing, 'me u etse-up the bit e lokelang ho khothaletsoa torque.
4 Ho kena ka hare
1.Tlosa sekheo 'me u theole ka hloko sekhahla ka sesebelisoa sa wellhead e le hore u se ke ua se senya.
2.Shrinkage, mahetla, ntja le setulo sa senotlolo sa borehole li lokela ho ba hlokolosi ha li phunya lesoba le se nang letho.
3. Qala pompo le mokelikeli oa ho cheka ka potoloho ho hlatsoa lesoba la buttom ha u phunya ho fihla sebakeng se ka bang limithara tse 30 ho ea tlase ho lesoba, 'me u potolose khoele ea ho phunya ka lebelo le tlase eseng ho feta 60rpm.
4.Atamela tlase hoo e ka bang halofo ea mithara.Potoloha metsotso e 5 ho isa ho e 10 ka phallo e felletseng.
5 Ho nahana
1.Ho khutlisetsa likarolo tse telele tsa lesoba la undergauge ha ho khothalletsoe.
2. Haeba ts'ebetso ea ho tsosolosa e hlokahala, ho kgothaletswa ka matla hore ts'ebetso ea ho tsosolosa e etsoe ka lebelo le phahameng la phallo ea phallo, boima bo khethehileng bo sa feteng 90N / mm (bophara), lebelo la rotary le se ke la feta 60 rpm moo ho ileng ha tšoaroa ha ho khoptjoa. ho.
6 Ho qhekella hanyane
1.Overusing lisebelisoa tsa ho bonts'a ha o batla o le haufi le tlase.Haeba WOB le torque li eketseha, seo se bontša hore bit ba attived at bottomhole.Sebelisa e seng ho feta 90N/mm, boima -on =bit le 40to 60rpm ho theha paterone ea bottomhole bonyane halofo ea mithara.
2.Bit break-in e felile 'me e lokela ho fetoloa RPM ho fumana motsoako o nepahetseng oa ho cheka parameter.
3.Drilling parameters phetoho e lokela ho khethoa ka har'a meeli ea mekhoa e khothalletsoang e bua ka mekhoa e khothalletsoang ea ho cheka mekhoa ea ho ntlafatsa.
