摘要: 核磁共振测井仪复合材料刻度系统的作用是把探头置入一个水套里通过采集地层孔隙流体信号进行孔隙度标定。本文对复合材料刻度系统的总体结构、筒体、筒体支架、铜箔屏蔽系统、循环系统等主要结构进行了优化设计,并通过有限元分析计算和对产品生产工艺的优化,在不增加刻度系统总重的前提下,提升了刻度系统整体的刚度和连接处的可靠性,使产品的整体结构更趋于合理化和操作便捷化。该复合材料刻度系统成功完成了仪器的刻度任务,可作为核磁共振测井技术研究的实验平台。

Abstract: The composite material calibration system of nuclear magnetic resonance logging tool is to calibrate the porosity by placing the probe in a water jacket and collecting the pore fluid signals of the formation. The overall structure, cylinder, cylinder support, copper foil shielding system, and circulation system of the composite material calibration system have been optimized and designed in this article. Through finite element analysis calculations and optimization of the production process, the stiffness of the entire calibration system and the reliability of the connections have been improved without increasing the total weight of the calibration system. This optimization has made the overall structure of the product more rational and convenient to operate. The composite material calibration system successfully completes the instrument calibration tasks and serves as an experimental platform for research in nuclear magnetic resonance logging technology.

Key words: nuclear magnetic resonance logging tool, composites calibration system, finite element analysis, structural design, bonding process
