石油测井仪器的工作环境极其恶劣。随着测井深度的增加,温度不断升高,压力也不断加大,温度会达到175℃,压力也会达到140MPa,加上泥沙、油污严重,自然伽马能谱测井仪螺纹连接粘扣导致无法使用甚至报废的情况时有发生。通过对自然伽马能谱测井仪螺纹连接方式和粘结过程的研究,分析了螺纹表面硬度、螺纹表面处理、螺纹几何参数、螺纹脂、使用或装配不当等因素对螺纹连接粘扣的影响,针对性的提出了防止和减少(减轻)螺纹粘扣的技术措施,为产品的防粘扣设计提供参考。
The working environment of oil logging instruments is extremely poor. With the increase of logging depth, the temperature is continuously rising, the pressure is also increasing, the temperature will reach 175 ℃, the pressure will reach 140MPa, coupled with sediment, oil pollution, gamma ray spectrometer logging thread adhesion Occurrence of non-use or even scrapped the situation occurred. Through the research on the thread connection and bonding process of Gamma-ray logging tool, the influence of thread surface hardness, thread surface treatment, thread geometry parameters, thread grease, improper use or assembly, etc. on the thread fastener is analyzed , Pointedly put forward the technical measures to prevent and reduce (mitigate) the Velcro fastener, and provide a reference for the anti-adhesive buckle design of the product.
