Amathuluzi we-Two-Stage ne-Speed ​​Speed ​​Drilling angazisebenzisa ngokuphelele izinzuzo zobuchwepheshe be-PDC bit rock rock esebenza kahle futhi aqhubeke nokwenza ngcono isilinganiso sayo semishini yokugoba ekwakhiweni okuphansi kokungena.

Kusukela kumgomo wokuqhekeka kwedwala, ithuluzi lezindawo ezimbili lokubhola ngejubane alihlukile kunembobo ejwayelekile ye-PDC. Umehluko omkhulu phakathi kwalokhu ukuthi indlela ethile yokuqhekeka kwamatshe ihlukile. Ithuluzi lokubhola lezigaba ezimbili ezinejubane linezinhlamvu ezimbili zokubhola ezinamamitha ahlukene. I-aubill drill bit drill iso, ikhipha ukucindezeleka kwangaphakathi edwaleni, bese isebenzisa ingxenyana encane yokubhola ubukhulu ukulandela idwala eliphukile. Ngoba intwana yokuqala yagqobhoza edwaleni Maphakathi nenqubo, inkambu yokucindezela yedwala elingezansi isishintshile, futhi idwala limelana nokwephuka. Amandla okuchoboza ancishisiwe, ngakho-ke ukusebenza kahle kwamatshe okubhidliza kwesibili kuyathuthukiswa. Ngaleyo ndlela kuthuthukiswe ukusebenza kahle kwemishini jikelele.

• Ukwakheka kwamadwala aqinile kakhulu kungabhalwa ngamamoto kusetshenziswa amadayimane noma ama-PDC bits.
• Izinga lokungena eliphakeme lingatholakala njengoba isivinini sokujikeleza siphezulu.
• Izovumela ukusakazwa kwequla ngaphandle kwesibalo samandla wehhashi noma i-torque ekhishwa yimoto.
