| Abstract: | It is a better selection to use small bicenter Ballas bits in sidetracking through φ139.7mm casing with windows.The optimum parameter,reaming effect,natural deflection and bit abrasive during drilling in 4 slimholes with the bits are preliminary analyzed.In the meantime,the problems such as well trajectory control,rate of penetration and cementing quality are also discussed. |
