摘要： A method for designing a secondary cutting structure for use in a bottom hole assembly, the method including defining initial design parameters for the secondary cutting structure and analyzing forces acting on the secondary cutting structure. Additionally, the method includes modifying at least one design element of the secondary cutting structure and simulating an effect of the modifying on both the secondary cutting structure and a primary cutting structure to determine if an improved condition is met. Also, a method for designing a drilling tool assembly, the method including defining initial drilling tool assembly design parameters including a primary cutting structure and a secondary cutting structure, and simulating a dynamic response of the drilling tool assembly. Additionally, the method includes adjusting at least one design element of the secondary cutting structure based on the dynamic response of the drilling tool assembly, determining if the adjusted design element improved a condition of the drilling, and repeating the simulating and adjusting until the condition is optimized.

摘要： A method for manufacturing a drilling tool includes machining a cutter pocket into a tool body. The cutter pocket has at least a front planar surface, a back planar surface, a first side surface between the front and back planar surfaces, and a second side surface opposite the first side surface and between the front and back planar surfaces. Once machined, cutting elements are placed in the cutter pocket and then brazed in the cutter pocket.
