摘要
实际钻进中,钻柱的振动不仅影响钻头轨迹,强烈的振动还有可能造成严重的钻井事故。以下部钻柱为研究对象,通过建立适当的动力学模型并用数学分析方法对钻柱进行动力学分析。可为优选现场钻井机械参数、避免钻柱发生疲劳失效等方面提供参考。
During practical drilling operation, the dynamic performance of drilling stem not only affects bit track but severe vibration,probably,causes drilling accident. Taking the bottom hole assambly as example,the dynamics analysis study was made for the drilling stem through dynamic mode using methamatical analysis method, which can offer the optimized drilling mechanical parameter and avoid fatigure failure happening
