| 摘 要： | 针对Φ89 mm反循环钻头取心短且带裙边的问题,对其碎岩过程进行有限元软件ANSYS数值模拟分析。根据分析结果提出合理设计方案,再对新钻头进行有限元数值分析,并与原设计进行对比分析,同时进行室内试验验证。结果表明,优化后的钻头取出的岩心较长、较完整且不带裙边,优化方案合理可行。

| Abstract: | Aiming at the problem of short coring sample with skirt of 89mm reverse circulation bit,numerical simulation analysis was made on the breaking process with finite element software ANSYS.According to the analysis results,reasonable design scheme was put forward.The further analysis was made on the new bit with finite element numerical simulation and the comparative analysis and indoor experiment on the original design were carried out.The results indicate that the optimized bit has longer,complete coring sample without skirt. |
