Roller cone drill biit IADC637 4 5/8″ (118mm)
Tsananguro yeChigadzirwa
Zvidhinha zvekuboorera zve API TCI tricone roller cone zvakaderedzwa mutengo kubva kuChina mutengesi wekuchera matsime
Tsananguro yeBit:
IADC: 637 - TCI journal yakavharwa bearing bit ine gauge dziviriro yemhando dzakasimba dzepakati nepakati dzine simba guru rekudzvanya.
Simba Rinodzvinyirira:
100 - 150 MPA
14,500 - 23,000 PSI
Tsananguro yeGround:
Matombo akaomarara, akakomberedzwa zvakanaka akadai se: matombo akaomarara esilica limestones, quarzite streaks, pyrite ores, hematite ores, magnetite ores, chromium ores, phosphorite ores uye granites.
Tinogona kupa maTCI bits akasiyana-siyana (kubva pa3 3/8" kusvika 26") uye akawanda emakodhi eIADC.
4 5/8" TCI tricone bit inoshandiswa zvakanyanya mukuchera matsime emvura, kutsvaga, gomba reHDD pilot, kuisa hwaro hwenheyo, ine dhizaini yegomba repakati, saka inogonawo kushanda pakuchera reverse circulation.
Bearing yacho yakavharwa, nguva yekushanda kwayo yakareba kupfuura ma open bearing roller bits. Conical shape tungsten carbide insert ine mwero wepamusoro wekupinza kupfuura ma spherical shape inserts ari pakuchera matombo akaomarara.
