| Abstract: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. |
