Outline of Final Research Achievements

Drill pipe strength evaluation and bit motions including stick-slip are primarily important problems in offshore drilling. Analytical models and evaluation methods for the above were established. However, it contains essentially important analytical conditions and parameters, and there are defined tentatively for the analysis.
Equations expressing the unknown conditions and parameters with drilling data therefore are newly derived by expanding the analytical results. Finally, this research suggested a drilling data-integrated simulation which is analysis method with analytical conditions and parameters determined by the surface drilling data acquired onboard drillship.
