| Abstract: | Based on static drag-torque model, the mathematical model used to monitor the friction factor between drill string and well bore, considering the features of the well trajectory and drill string in Extended-Reach Wells (ERW), is founded. The methods used to diagnose the wellbore cleaning degree, smooth degree, differential sticking degree, undergauge, sloughing and key-set are put forward in this paper. |
