摘　　要：井下钻具的工作安全性是安全钻井施工的重要技术指标。以钻具工作安全性评价中的力学特性评价为研究内容,提出了基于钻柱系统动力学和现代CAE技术的井下钻具力学特性评价新方法。相比传统方法,该方法可以更深入准确地完成钻具的力学评价工作,为重点井,例如,探井、特殊工艺井的安全施工提供可靠的理论支撑。Drilling tool＇s working security is one of the important technical target of safety drilling. This article take drilling tool＇s mechanical characteristics evaluation, which is one part content of drilling tool＇s working security, as the research subject, and proposes a new evaluation method of drilling tool＇s mechanical characteristics based on drilling string system dynamics and CAE technology. Compared with traditional method, this method may thoroughly and accurately complete drilling tool＇s mechanics appraisal work. In the key well, such as exploratory well and special-technics well, this method can provide more reliable theory assistance.
