Abstract

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
