Mata kōhatu Tricone IADC417 8 1/2″(215.9mm)
Whakaahuatanga Hua
Kei roto i te taonga te TCI Tricone Rock Drill Bit mō te hanganga toka waenga ki te mārō.
Whakaahuatanga Moka:
IADC: 417 - Mata pere hiri TCI me te tiaki ine mō ngā hanganga ngohengohe me te kaha pēhi iti me te kaha keri teitei.
Kaha Whakapūmau:
65 - 85 MPA
9,000 - 12,000 PSI
Whakaahuatanga Whenua:
He roa ngā mokowā o ngā kirikiri ngohengohe rawa, ngā toromite, ngā kirikiri onepū, ngā uku, ngā tote me ngā kohatu kōhatu, kāore i te tino kiato.
Ka taea e Far Eastern Drilling te tuku i ngā mata wiri tricone o ngā rahi rerekē (mai i te 3” ki te 26”), me te nuinga o ngā waehere IADC.
Mata kōhatu Tricone IADC417 8.5"(215.9mm)
1>Rahi o te moka 8.5"(215.9mm) me te hononga miro4 1/2 pine noa mō te keri poka hohonu pērā i te keri poka hinu me te hau, ā, he rahi noa hoki mō te keri poka pairati whakapae. Ka karangatia hoki e mātou ko te 215mm, ko te 216mm rānei. He moka whakauru tungsten carbide.
2>Kei a mātou te peera hiri Elastomer me te kounga me te utu noa, me te peera hiri mata-konganuku me te mahi me te utu teitei ake.
3>Mēnā he poka hohonu rawa te keri, he tere te hurihuri, nō reira ka tūtohu mātou kia neke atu i te 1000 mita ngā mata tricone hiri-mata-konganuku i te hohonu o te keri. Mō ngā kōhatu mārō me ngā kōhao tawhiti kore-awaawa e neke atu ana i te 300 mita te roa, ka tūtohu anō mātou kia neke atu i te 300 mita ngā mata tricone hiri-mata-konganuku.
4>Mēnā he keri puna wai, he keri puna pāpaku, he keri poka pairati poto ake rānei, he pai ake te mahi a ngā moka tricone hiri elastomer (rapa).
