Rotary roller bits IADC637 9 7/8 ” (250.8mm)
Tlhaloso ea Sehlahisoa
Li-drill drill tsa API tsa TCI tse nang le theko e theotsoeng setokong ho tsoa fekthering ea China bakeng sa liforomo tse thata.
Tlhaloso ea Bit:
IADC: 637 - Koranta ea TCI e tiisitsoe ka sekhahla se sirelelitsoeng ka gauge bakeng sa liforomo tse thata tse mahareng tse nang le matla a phahameng a khatello.
Matla a Khatetsang:
100 - 150 MPA
14,500 - 23,000 PSI
Tlhaloso ea Motheo:
Majoe a thata, a kopantsoeng hantle joalo ka: li-limestones tse thata tsa silica, li-quarzite streaks, pyrite ores, ores hematite, magnetite ores, chromium ores, ores phosphorite le granite.
Ho Drilling Bochabela bo Hole ho ka fana ka likotoana tsa TCI ka boholo bo fapaneng (ho tloha ho 3 3/8" ho isa ho 26") le boholo ba likhoutu tsa IADC.
9 7/8" ke 250mm ka bophara, khoele ea khoele ke 6 5/8 reg pin ho latela litlhaloso tsa API.
IADC537 e bolela hore tricone roller bit e loketse ho cheka mafika a thata joalo ka quarzite streaks, granites, joalo-joalo. The bearing ke elastomer e tiisitsoeng ho eketsa bophelo ba ho sebetsa.
Tungsten carbide inserts(TCI) ke motsoako o thata haholo oa ho cheka majoe a thata, serethe sa likhoune le mokokotlo oa letsoho li kentsoe ka meno a Tungsten Carbide.
Ke boholo bo tloaelehileng tšimong ea merafo, ho phunya lesoba le phatlohang. Mo merafong, nomoro ea pele ea khoutu ea IADC hangata ke 6,7,8, 'me palo ea boraro hangata ke 2 le 5.
Ho ea ka litlhaloso tsa IADC bakeng sa "tricone bit,"2" e bolela "rolara e bulehileng" e tloaelehileng, 'me "5" e bolela "rolara e tiisitsoeng" e nang le tšireletso ea gauge.
Linaheng tse ling, 9 7/8"(250.8mm) hangata e sebelisoa ho cheka seliba sa metsi le seliba sa mocheso oa mocheso o chesang.
Ka hona, bakeng sa lits'ebetso tse fapaneng, re lokela ho khetha likotoana tse nepahetseng tsa tricone.
