Wiri kōne roera biit IADC637 4 5/8″ (118mm)
Whakaahuatanga Hua
Ngā mata keri kōne roera API TCI tricone rarawe me te utu whakaheke i roto i te taonga mai i te kaiwhakarato Haina mō te keri puna
Whakaahuatanga Moka:
IADC: 637 - Mata pere hiri TCI me te tiaki ine mō ngā hanganga pakeke waenga me te kaha pēhi teitei.
Kaha Whakapūmau:
100 - 150 MPA
14,500 - 23,000 PSI
Whakaahuatanga Whenua:
Ngā toka mārō, kua pai te whakapiripiri, pērā i: ngā kōhatu kōhatu mārō, ngā rārangi quarzite, ngā konganuku pyrite, ngā konganuku hematite, ngā konganuku magnetite, ngā konganuku chromium, ngā konganuku phosphorite me ngā granite.
Ka taea e mātou te tuku atu i ngā momo rahi o ngā moka TCI (mai i te 3 3/8" ki te 26") me te nuinga o ngā waehere IADC.
E whakamahia whānuitia ana te mata tricone TCI 4 5/8" mō te keri puna wai, te tūhura, te poka pairati HDD, te whakatū pou turanga, he hoahoa poka jet pokapū tōna, nō reira ka taea hoki te whakamahi mō te keri tohanga whakamuri.
He hiri te peera, he roa ake te ora mahi i ngā porotaka peera tuwhera. He tere ake te werohanga o te whakaurunga tungsten carbide āhua kōniko i ngā whakaurunga āhua porowhita i roto i te keri toka mārō.
