PZ系列组合牙轮钻头及其嵌岩技术的研究

Study on PZ Modular Roller cone Bit and Rock Drilling Technology

摘要:

介绍了ＰＺ系列组合牙轮钻头的技术参数、结构特点及使用性能，通过对单牙轮的受力分析，提出了ＰＺ系列组合牙轮钻头最低钻压理论值和最高转速值，从而为钻头合理使用提供了理论依据。

Abstract:

Technical parameters, structural features and performance of PZ modular roller cone bit are presented. Theoretical value of the lowest bit pressure and value of highest rotary speed are put forward with the analysis on bit pressure acted on single roller cone, thereby theoretical basis is achieved for the proper use of the bit.
