Abstract: | Well trajectory optimization technology, wellbore cleaning technology, and friction reducing torque technology are all large-displacement well drilling technologies. According to the research, the drilling aging effect will be directly affected by the torque from the large displacement well drilling. The analysis of the torque will greatly help to control the change of the wellbore trajectory and also reduce and prevent downhole accidents. |
