Reaming While Drilling Drillstring Structure Optimization and Application Performance Evaluation

Shiyou jixie, 2016
The reaming tool BHA is the most important controllable factor during reaming while drilling operations,whereas the irrational drill string structure could lead to intensified drill string vibration.In view of this,the drill string-formation finite ...
