摘要

螺纹连接通常用于连接石油钻具（PDT）。在本研究中，我们使用纳米铜（NaCU）和环氧树脂粘合剂制备了一种基于 NaCU 的防摩擦涂层（NaCU-AFC）。此外，我们还使用有限元分析（FEA）验证了 PDT 螺纹接头接触齿面的扭矩和压力分布。结果表明，NaCU-AFC 能有效降低 35.66% 的扭矩，并显著提高防粘性能，从而延长 PDT 的使用寿命。总之，这项研究为 PDT 涂层工艺的实际应用提供了宝贵的启示。

Finite element stress analysis of nano copper-based anti-friction coating for improved threaded connections in petroleum drilling tools

Threaded connections are commonly used in connecting petroleum drilling tools (PDTs). In this study, we use nano copper (NaCU) and epoxy-resin binder to prepare a NaCU-based anti-friction coating (NaCU-AFC). Furthermore, we use finite element analysis (FEA) to validate torque and pressure distribution on the contact tooth surface of threaded joints of PDTs. The results demonstrate that the NaCU-AFC can effectively reduce torque by 35.66%, and significantly improve anti-sticking performance, thereby extending the service life of PDTs. In summary, this study provides valuable insights for practical applications in coating processes for PDTs.
