三分量阵列感应模拟装置的水平线圈系在测量时受井眼影响比阵列感应更为严重，数值计算不能准确模拟短阵列的影响特性，须通过物理模拟装置测量修正。在开发出水罐中三分量阵列感应测井响应数值计算软件的基础上，研究了三分量阵列感应测井仪器在模拟装置中的响应特性，给出标准8in井眼中泥浆和地层电导率相等时模拟装置测量的适用条件。结果表明：水平线圈系测量误差大于垂直线圈系；装置不适合最长水平线圈系子阵列8；对于子阵列1至7，水罐中的电导率合适时，可以忽略大地电导率的影响。

The horizontal coil of tri-axial array induction is more seriously affected by the borehole than the array induction.The numerical models can not correctly simulate the influencing charac-teristic of the short sub-array.Thus the response characteristics of tri-axial array induction log-ging must be measured and modified by the physical device.Based on the numerical calculation software of the tri-axial array induction logging in the water test tank,the logging response char-acteristics of tri-axial array induction logging are analyzed.The application conditions of the test device response are given in the standard 8in borehole.The results show that the measuring error of the horizontal coils is greater than that of the vertical coils′.The device is not suitable for the longest sub-array 8.For sub-array 1 to 7,when the liquid conductivity in tank is appropriate′the ground effect can be ignored.
