Stress related placement on engineered superabrasive cutting elements on rotary drag bits |
摘要 |
A drill bit employing selective placement of cutting elements engineered to accommodate differing loads such as are experienced at different locations on the bit crown. A method of bit design and cutting element design to achieve optimal placement for maximum ROP and bit life of particularly suitable cutting elements for a given bit profile and design, as well as anticipated formation characteristics and other downhole parameters.
