| 英文摘要: |
| The moving coordinate iterative method is used to analyze unknown boundary and geometricnonlinear forces and deformations of drillstring in annulus. The friction is in troduced in theequilibrium calculation. The models of the tri-dimentional analysis are derived.It is shown bycomputation that the method and the models are simple,convenient and reliable and thecomputation can be simplified by the method in practical applications. |
