| Abstract: | The static mechanics of down well string is analysed, by using finite element technique, the influences of stabilizer position,wellbore variability. drill collar stiffness etc. in static condition on bit side force and corner are discussed to provide theoretical basis for selecting drill tool assembly and determining drilling parameters at the site. The result has been verified by directonal well practices in oil fields. |
