摘要： Embodiments including methods comprising providing a wellbore in a subterranean formation having a wellbore length; providing a proposed cement slurry formulation; calculating a normalized pressure at a point along the wellbore length based on properties of the proposed cement slurry formulation and properties of the wellbore in the subterranean formation; manipulating the proposed cement slurry formulation based on the normalized pressure so as to produce a fluid invasion resistant cement slurry; introducing the fluid invasion resistant cement slurry into the wellbore; and cementing the fluid invasion resistant cement slurry in the wellbore.
