IADC | WOB(KN/mm) | RPM(r/min) | Applicable Formations |
527 | 0.3-0.7 | 120-50 | Soft formation with low compressive strength and high drillability,such as mudstone,gypsum,salt,soft shale,soft limestone,etc |
547 | 0.3-0.7 | 100-50 | Soft to medium formation with low compressive strength,such as medium soft shale,medium soft limestone,medium soft sandstone,medium for formation with harder and abrasiver interbeds,etc. |
617 | 0.4-0.8 | 90-50 | Medium hard formations with high compressive strength,such as hard shale,limestone,sandstone,dolomite,etc. |
It is suitable for sidetracking,deep well drilling and old well repairing.
1 Two watercourse can improve washing endurance and prevent mud.
2 Silver-plated at sliding surfaces of cone bearing to strength self-lubricating effect,and improve the bearing of wear-resisting life.
3 The bit inlaid with diamond compact teeth can be more effectively improve working life.
4 Two advanced high-saturated buna-N rubber seal rings are used for journal and bearing pin sealing,which ensured the high reliability of the bearing seal structure.
5 The bearing is improved by applying hard facing layer on head bearing surface,extended working life.
