oscillator waipēhi
whakamahi oscillators waipēhi pini waipēhi ki te whakaputa kawenga wiri axial o drill string me hinga te waku borehole. Kua oti pai tono te reira i roto i Wells poutū, motor kōhao arahina, hurihuri kōhao arahina, displacement nui Wells me tokauku hau awa kōhao.
Hua Hangarau:
1. Te whakapai ake whakawhiti taimaha downhole
2. tōtika te whakapai ake auau kōhao
3. hira whakaiti waku resistance
4. Hototahi ki MWDS / LWD
5. hāngai pai te reira ki nga mea katoa o paraire drill
6. takotoranga ake

Reira te nuinga ngā o e toru ngā wāhanga: mana kōmata, kōpae whakaminenga piha me pūnaha oscillation.
Ko te waku i waenganui i te taiepa pai, me te taputapu kōhao ko te whakaputa ke i pateko ki hihiri.
