摘　　要：测量信号刻度和趋肤效应校正在传统双感应测井信号处理中起着重要的作用。详细研究了传统分段线性乘加因子和函数拟合趋肤效应校正方法及其存在的问题 ,并给出这些方法的适用范围。提出了一种基于归一化因子的趋肤效应校正新方法。误差分析和地层模型模拟表明 ,在感应测井的适用范围内 ,新方法优于传统的方法。此外 ,对传统测量信号刻度中的刻度系数、刻度点和刻度电阻进行了重新计算和检验。On Correcting Skin Effect and Calculating Scale Coefficient in Dual Induction Logging.WLT, 2001, 25(4):261-265 The scale of measurements and the correction of skin effect play a great role in the signal processing in dual induction logging. This paper investigates two skin effect correction methods, i.e., the multiplying adding factor and the function fitting, used in dual induction logging. A normalized factor correction method is proposed. Error analysis and formation simulation show it has a good advantage over the conventional induction logging in induction logging limitation. Finally, the scale coefficient, the scale position and the scale resistance in dual induction logging are rechecked and renewed.
