| Abstract: | On the basis of numerical approximation a maih mtical modelfor calculating the directional wellbore axis direction is established. The model is simple in programming and calculating. The calculation results are in good agreement with field results and analytical solutions. It can simulate wellbore axis and provide reliable data for finite element analysis of forces and deformations of the drillstring in a directional well. |
