一种PDC钻凿特性测定方法
摘要：
本发明涉及钻头测定技术领域的PDC钻凿特性测定方法，在室内条件下，利用人造聚晶金刚石(PDC)钻凿特性测定试验装置进行，使用PDC模拟钻头进行PDC钻进特性试验，计算PDC的钻进特性因子D；使用PDC磨铣钻头进行PDC磨铣试验，计算PDC的磨铣特性因子P，进而计算PDC的钻凿特性其优点是可以测量PDC作为切削齿在受力与旋转并伴有无规律振动、冲击状态下PDC的钻凿特性。其测试方法简单、安全、准确，测试结果更接近实际测试结果。
摘要（英）：

The present invention relates to the technical field of drill measuring, and discloses a PDC drilling characteristic measuring method, under indoor conditions, a man-made polycrystalline diamond PDC drilling characteristic measuring test device is used, PDC is used for simulating a drill for PDC drilling characteristic tests for calculation of PDC drilling characteristic factor D; a PDC milling bit is used for PDC milling tests for calculation of PDC milling characteristic factor P, then PDC drilling characteristics can be calculated; and the advantages are as follows: the method can be used for measuring the PDC drilling characteristics of PDC as cutting teeth under states of force and rotation accompanied with irregular vibration and shock. The measuring method is simple, safe and accurate, and test results are closer to actual test results.
