科学钻探岩芯低损耗成分测试和物性测量的探索与实践
Exploration and practice of low-loss chemical composition analysis and physical property measurement for scientific drilling core
摘要
Abstract
Scientific drilling cores are valuable physical materials for earth science research.They directly reflect the deep structure,material composition,and geological history of the Earth.These cores hold considerable importance and unique value for research in multiple disciplines including geology,geophysics,geochemistry,materials science,and information science.This study aims to explore and practice methods for low-loss chemical composition analysis and physical property measurement of scientific drilling cores to achieve the protection and efficient utilization of precious scientific drilling core resources.The paper proposes a scientific plan for sample layout and collection,then elaborates on the sampling process for physical property measurements,conducting wave speed,density,magnetic,and electrical measurements on different specifications of samples.For the chemical composition analysis of cores,a low-loss testing strategy is proposed,including ensuring single-analysis dosage,selectively analyzing trace elements,and handling special cases.Finally,the importance of sample repositioning and preservation of surplus samples is emphasized.The"low-loss chemical composition analysis and physical property measurement"method for scientific drilling cores proposed in this paper has been practiced during project implementation and has achieved preliminary application results.It holds significant importance for promoting the protection and efficient use of scientific drilling cores.关键词
