Design and development of equipment for testing PDC drilling features

Constrained by the mechanical properties of its cutter material, PDC bit is met with great challenge from applications and technology advantages. In order to improve the quality of PDC bit fundamentally, it is critical to develop a set of equipment for testing engineering properties of PDC as cutter material while drilling in rocks in force and rotation accompanied by irregular vibration and shock. Based on elaborating the functions of the functions and design of overall structure of the equipment for testing PDC drilling features, this paper briefly introduces the process of prototype development, accuracy test results of main technical parameters, technical performance and innovations. Research results provide reference for the development and performance testing of high-performance PDC bit.
