摘要
根据阵列感应测井仪刻度原理,导出阵列感应测井仪电导率与刻度环串接电阻阻抗之间的关系,采用复系数电压信号刻度法,选用3种直径的刻度环在各子阵列相应的刻度点能对各子阵列进行刻度得到刻度增益值。给出了在半空间测量阵列感应测井仪线圈系误差的校正图版,介绍了仪器的刻度方法。
According to calibration principle of array induction logging tool,derived is the relationship equation between conductivity and impedance of calibration loop.Using plural coefficient voltage signal calibration method,received are the scale gain values of sub array which is calibrated in calibration position with three kinds of diameters calibration loops.Proposed are correction charts for measuring the sonde errors of array induction logging tool in half space and the calibration details of array induction logging tool.
