AB - In this paper, a 3-D geomechanically model and a three-pressure profile along  the wellbore trajectory were established to determine a reasonable drilling  mud density window by establishing calculation methods and correlations  between geomechanically parameters. On the basis of drilling mud density  window, combined with the principle of ERW extended limit, the analysis  models of the limits of den­sity and flow rate of drilling mud were  established, respectively, with the objective that the extension limit can  fulfill the design depth of the wellbore. The results of the practical  application illustrate the feasibility and correctness of this preferred  model for the combination of drilling mud density and flow rate.
