本文详细介绍了对PDC钻头切削齿在实际工作条件—重叠和覆盖条件下破岩规律的研究结果。主要内容包括研究方法、影响重叠和覆盖条件下切削齿破岩载荷的因素及规律、研究结果在钻头设计中的应用等。
This article describes in detail the research results on the breaking rules of PDC bit cutting teeth under the actual working conditions-overlap and covering conditions. The main contents include the research methods, the factors and rules affecting the rock breaking load under the overlapping and covering conditions, and the application of the research results in the bit design.
