Drill bit ntchito malangizo
1 pang'ono kusankha
1.Chonde werengani mafotokozedwe a lithology ndi zolemba pang'ono za zitsime zoyandikana nazo mosamala, ndikusanthula mapangidwe ake.
2.Kusankha mtundu woyenera malinga ndi lithology.
2 Kukonzekera musanabowole
1.Yang'anani pang'onopang'ono kuwonongeka kwa thupi, ocheka otayika kapena oyika ndi zina. Onetsetsani kuti palibe zonyansa pa dzenje la buttom, ndipo yeretsani dzenje pansi ngati kuli kofunikira.
2.Bit iyenera kusamaliridwa mosamala kuti musawononge odula ndi zinthu zolimba.
3.Check ngati pali kuwonongeka kulikonse pa bit cuttes ndi ngati pali nkhani yachilendo mkati pang'ono.
4.Check ngati kukhazikitsa nozzle ndi kukwaniritsa zofunika, ndi kusintha nozzles ngati n'koyenera.
3 Kuzindikira pang'ono
1.Clean bit threads ndikupaka girisi pa ulusi.
2.Gwiritsani chophwanyira pang'ono, tsitsani chingwe chobowola pa pini ndikugwirizanitsa ulusi.
3. Pezani pang'ono ndi chophwanyira mu rotary bushing, ndipo pangani pang'ono kuti muvomereze torque.
4 Kuyenda mkati
1.Chotsani chosweka ndikuchepetsa mosamala pang'ono kupyolera mu chipangizo cha chitsime kuti musachiwononge.
2.Kuchepetsa, phewa, galu ndi mpando wofunikira wa pobowo uyenera kukhala wosamala ukadutsidwa pa dzenje lopanda kanthu.
3. Yambani mpope ndi kuzungulira pobowola madzimadzi kutsuka buttom dzenje pamene kubowola pa mfundo pafupifupi 30 metres pansi pa dzenje, ndi kuzungulira chingwe kubowola pa liwiro otsika osapitirira 60rpm.
4.Yandikirani pansi pafupifupi theka la mita.Kuzungulira kwa mphindi 5 mpaka 10 ndikutuluka kwathunthu.
5 Kulingalira
1.Kutulutsa zigawo zazitali za dzenje la undergauge sikuvomerezeka.
2.Ngati ntchito yobwezeretsanso ikufunika, tikulimbikitsidwa kuti ntchito yobwezeretsanso ichitike ndi kuchuluka kwa kuthamanga kwa kuthamanga, kulemera kwake kwapang'ono kosapitilira 90N/mm (m'mimba mwake), liwiro lozungulira lisapitirire 60 rpm pomwe zidakakamira popunthwa. mu.
6 Kuphwanya pang'ono
1.Overusing kusonyeza zida pamene bit approch bottomhole.Ngati WOB ndi makokedwe kuwonjezeka, zimene zikusonyeza pang'ono kuti attived attived at bottomhole.Use osapitirira 90N/mm, kulemera -on = pang'ono ndi 40to 60rpm kukhazikitsa bottomhole chitsanzo osachepera theka la mita.
2.Bit break-in yatha ndipo iyenera kusinthidwa RPM kuti ipeze kuphatikiza koyenera koboola.
3.Drilling magawo kusintha ayenera kusankhidwa mu malire a analimbikitsa magawo amanena analimbikitsa pobowola magawo kukhathamiritsa njira.
