摘要
A method of designing a downhole drilling tool may include generating a three dimensional (3D) downhole drilling tool model and simulating engagement of the drilling tool model with a 3D model of a borehole bottom. First and second cutting zones of first and second cutting elements may be determined based on areas of the first and second cutting elements that engage the borehole bottom, where the first and second cutting zones respectively have first and second cutting zone shapes. First and second cutting forces for the first and second cutting elements may be calculated based on the respective first and second cutting zone shapes. A drilling efficiency of the drilling tool model may be modeled based at least on the first cutting force and the second cutting force and a design parameter of the drilling tool model may be modified based on the drilling efficiency of the drilling tool model.
