论述了在半空间测量水平放置阵列感应测井仪器线圈系误差的理论和方法,给出了误差校正图版和误差校正公式;讨论了半空间中均质地层电导率对仪器常数刻度值的影响。将阵列感应测井仪器水平悬挂在距地面两个不同的高度处,根据预先确定出的背景信号与信号差之间的关系,可以在无需知道地层电导率的情况下确定出每个单元阵列不同输出曲线的线圈系误差。计算结果表明:若线圈系距地面高度较高,且地层电导率值较小,则地层对仪器常数刻度值的影响可以忽略
The theory and method of measuring the coil error of the arrayed induction logging instrument in half-space are discussed. The error correction plate and the error correction formula are given. The influence of the homogeneous formation conductivity in the half-space on the constant value of the instrument is discussed. Arranging array-sensing logging tools horizontally at two different heights from the ground, each of the cell arrays can be identified without knowing the conductivity of the formation, based on a predetermined relationship between the background signal and the signal difference Coil output curve error. The calculation results show that if the coil height is higher than the ground and the conductivity of the formation is small, the influence of formation on the scale value of the instrument can be neglected
