【摘要】 朱军等．感应测井是的相位移误差．测井技术，１９９４，１８（４）；２４８～２５３感应测井仪中Ｒ信号和Ｘ信号测量不准确的一个主要原因是仪器中的信号发生相位移。本文分析了相位移产生的原因，定量地估计了相位移对Ｒ信号和Ｘ信号检测带来的误差，提出了感应测井中信号检测所要求的相位精度。本文最后还指明了减小相位移，提高检测精度的办法。更多还原

【Abstract】 Inaccurate measurement of R and X signals in prior-art induction logging tooloften results from phase shift of the tool signals. Included in this paper are causeanalysis of phase shift,quantitative estimation of R and X signal errors from theshift and the phase accuracy required for signal detection. Finally, how to reducephase shift and improve signal measurement accuracy have been described in the paper.更多还原
