摘要
对含金属心棒阵列感应测井仪器的线圈系模型在含井眼地层中的响应及该模型的仪器常数刻度值进行了计算，计算中同时考虑了线圈系的有限尺寸。给出了含复宗量变型Ｂｅｓｅｌ函数无穷限振荡积分的数值计算方法和含金属心棒线圈系的井眼校正图版。计算结果表明，金属心棒对输出信号的影响是恒定的，含铜心单元阵列的井眼校正曲线保持了原曲线的主要特性。
he response in media of formation with borehole and the calibrating value of the tool
factor of array induction logging coils model with metal mandrel are calculated. The finite size
of the coils is considered during the calculation. The mathematical method for calculating the
infinite oscillating integration with complex argument modified Bessel functions is discussed.
The borehole correction charts of the coils with metal mandrel are given. The results indicate
that the influence of the metal mandrel on output signals is stable. The borehole correction
curves of the array with copper tubing keep the main characteristics of the old curves, and the
mud has different influence on output signals of different arrays.\=
