After basic transforming to catenary expression of analytical geometry and basic parameters substituting, a new computation model of catenary trajectory design for extended-reach drilling (ERD) is derived and established. The computation correctness of the new model is verified by comparison between computation results with the new model and with similar western software package. The new model removes the hyperbolic expression, has a lower computation complexity and is easier for site engineers to understand and utilize. A detailed analysis for computer computation complexity by utilizing of this new model is conducted, analysis results show that the computation complexity of new model is obviously less than those currently utilized models.
