摘要： A method for improving finite element analysis of threaded connections includes selecting at least one thread parameter for a female connection and a corresponding male connection. In two dimensions a thread form is calculated for the female connection and the male connection based on the at least one parameter. In two dimensions a geometry is calculated of the female connection and the male connection based on the thread form. In two dimensions the female connection and the male connection are segmented into predefined areas. A finite element analysis mesh is calculated based on a predetermined number of nodes for each of the predefined areas and a selected number of mesh layers for each predefined area. The two dimensional female connection and male connection are assembled. The two dimensional mesh on the assembled connections is used as input to a finite element analysis of the threaded connection in three dimensions.

摘要： A system and a method analyze fatigue damage of a bottom hole assembly (“BHA”), and more specifically, use a multi-scale approach for fatigue analysis of a BHA. Three length scales may be used in modeling of a BHA, namely the BHA scale, the component scale and the feature scale. Loading conditions for each collar/tool of the BHA may be determined, such as by use of a beam model, and may be applied to the finite element models for the collar/tool to determine the fatigue damage of each fatigue susceptible feature of each collar/tool. A cumulative fatigue damage of each critical feature may be determined, and the weakest component of the BHA may be identified. Prognostic and diagnostic implementation with well survey and drilling data may monitor fatigue damage of critical components of the BHA.
