岩石物性是地质与地球物理研究的纽带,也是地学研究中一个相对薄弱的环节,本文通过我国某油田若干钻井样品的实际测量,分析对比了各种磁化率测量结果之间的异同,总结出岩石磁化率在应用中的几点认识:(1)野外非单位体积的测量结果用于地层结构反演时,是会造成较大误差的;(2)采用多方向,多次测量平均的测量方式,可减小误差;(3)避免使用混合标本;(4)选择适合样品的测量档位.

Physical property of rock, as the bridge between geology and geophysics, is a weak part in geoscience. The author measured rock magnetic susceptibility by using a lot of samples from an oilfield located in China, and analyzed the data of sorts, then summarized some experiences in measuring rock magnetic susceptibility. We conclude that the field result is the relative value, multi-measuring in multi directions shoud be adopted, mixturd samples should be exclusive and suitable scales of samples are to be chosen.
