SIMULATING THE DYNAMIC RESPONSE OF A DRILLING TOOL ASSEMBLY AND ITS APPLICATION TO DRILLING TOOL ASSEMBLY DESIGN OPTIMIZATION AND DRILLING PERFORMANCE OPTIMIZATION

摘要

A method for simulating the dynamic response of a drilling tool assembly is disclosed. Methods for simulating drilling tool assemblies may be used to generate a visual representation of drilling, to design drilling tool assemblies, and to optimize the drilling performance of a drilling tool assembly. One method for designing a drilling tool assembly includes simulating a dynamic response for the drilling tool assembly, adjusting a value of at least one drilling tool assembly design parameter, and repeating the simulating. The method further includes repeating the adjusting and the simulating until at least one drilling performance parameter is determined to be at an optimum value. One method for optimizing at least one drilling operating parameter for a drilling tool assembly includes simulating a dynamic response of the drilling tool assembly, adjusting the value of at least one drilling operating parameter, and repeating the simulating. The method further includes repeating the adjusting and the simulating until at least one drilling performance parameter is determined to be at an optimal value.
