摘要
通过大量的实验数据 ,对三牙轮钻头在井底振动时干扰力的幅值和频率进行了全面而细致的分析 ,摸索出了其在井底的振动规律 ,提高了井下钻具动力学分析的准确度 ,可在一定程度上减少钻具失效。
The interfering force value and frequency were analyzed fully with a lot of tested data while vibrating for the tri cone bits in the bottom of well. The vibration rules of tri cone bits in the bottom were found and increased the accuracy of dynamics analysis of drilling tools in the bottom. The drilling tool malfunction and cost were reduced in some extent.
