TCI tricone bit IADC417 17.5″(444.5mm)
Whakaahuatanga Hua
Wheketere API me te ISO o te TCI Tricone Bit IADC417 17 1/2 inihi me te utu whakaheke.
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.
Kei a mātou ngā mata tapahi TCI me te niho rino e ai ki ngā rauemi tapahi.
I tapaina hoki e mātou ngā mata tricone niho rino he mata tricone niho mira nā te mea ka hangaia ngā niho e te mīhini mira, ko te mata kōne he mea mārō ki te tungsten carbide.
He pai ngā wiri niho rino mō ngā hanganga tino ngohengohe, he iti te kaha pēhi, he teitei hoki te āheinga ki te wiri. He mea nui kia whiriwhiria ngā mata wiri e tika ana mō te kaupapa keri. Ka taea e tā mātou miihini te hoahoa i te tuhi hei whiriwhiri i ngā mata wiri pai rawa atu māu.
