Fa'atonuga ole fa'aogaina ole vili
1 bit filifiliga
1. Fa'amolemole faitau ma le fa'aeteete fa'amatalaga lithology ma fa'amaumauga laiti o vaieli lata ane, ma au'ili'ili uiga fa'avae.
2. Filifilia ituaiga talafeagai e tusa ai ma le lithology.
2 Sauniuniga a'o le'i viliina
1. Su'esu'e le vaega muamua mo le faaleagaina o le tino, leiloa tipi po'o mea fa'apipi'i ma isi mea. Ia mautinoa e leai ni mea leaga i luga o le pu, ma fa'amama le pu pito i lalo pe a mana'omia.
2.Bit e tatau ona taulimaina ma le faʻaeteete ina ia le faʻaleagaina ni tipi ma mea faigata.
3. Siaki pe i ai ni mea leaga i luga o fasi tipi ma pe i ai ni mea mai fafo i totonu ole fasi.
4. Siaki pe faʻapipiʻi faʻapipiʻi e fetaui ma manaʻoga, ma sui nozzles pe a manaʻomia.
3 Faailogaina le fasi
1. Fa'amama filo ma fa'asusu i filo.
2. Fa'apipi'i le va'a i le u'amea, tu'u i lalo le manoa vili i luga o le pine ma fa'apipi'i filo.
3. Su'e le u'amea ma le va'a i totonu o le fa'ato'aga fa'asolosolo, ma fa'alelei le pito e fautuaina.
4 Tu'u i totonu
1. Aveese le gau ma tuutuu i lalo ma le faaeteete le u'amea i totonu o le masini vaieli ina ia aua nei faaleagaina.
2. Shrinkage, tauau, dogleg ma le nofoa autu o le lua e tatau ona faaeteete pe a u i le avanoa avanoa.
3. Amata pamu ma vili le vai e fufulu ai le pu pe a vili i se tulaga e tusa ma le 30 mita i lalo ole pu, ma sui le manoa vili i le saoasaoa maualalo e le sili atu i le 60rpm
4. Fa'alatalata i lalo e tusa ma le afa mita.Fa'asalalau mo le 5 i le 10 minute ma le tafe atoa.
5 Reaming
1.Reaming vaega uumi o undergauge pu e le fautuaina.
2. Afai e manaʻomia le faʻaogaina o le faʻaogaina, e matua fautuaina lava e tatau ona faia le faʻaogaina o le reaming ma le maualuga o le tafe o le tafe, mamafa faʻapitoa i luga o le bit e le sili atu i le 90N / mm (diameter), le saoasaoa o le rotary e le sili atu i le 60 rpm lea na pipii ai pe a paʻu. i totonu.
6 Bit soli-i totonu
1. Overusing fa'aaliga meafaigāluega pe'ā fa'alatalata mai i lalo.Afai e fa'atupula'ia le WOB ma le torque, o lo'o fa'aalia le pu i lalo. Fa'aoga le sili atu i le 90N/mm, mamafa-i = bit ma le 40 i le 60rpm e fa'avae ai le mamanu pito i lalo ia le itiiti ifo ma le afa mita.
2.Bit break-i ua mae'a ma e tatau ona fetuutuunai RPM ina ia maua se tuufaatasiga parakalafa vili sili ona lelei.
3.Drilling tapula'a fetuutuunai e tatau ona filifilia i totonu o le tapula'a o le fa'ata'ita'iga fautuaina e fa'asino i le fa'ata'ita'iina o fa'ata'ita'iga fa'ata'ita'iga fautuaina.
