摘　　要：介绍了SL15 0 3感应测井仪的现场刻度原理和感应测井基值的调试方法。从仪器的角度对感应测井曲线产生异常现象的原因进行了理论上的推导和分析 ,并用实例验证了感应测井曲线异常的原因是由于感应测井基值调试不当以及刻度不及时造成的。针对感应测井曲线的这些异常现象 ,系统地总结了一套感应测井基值的调试方法。最后 。Principle of dual induction tool's field calibration and method for adjusting dual induction log zeros are introduced in this paper. The reasons for the abnormal phenomenon of induction logging curves from the tool are induced and analyzed in theory. One is incorrect adjustment of the induction log zero, the other is no calibration in time. A case example shows the derivation and analysis are right. Furthermore, a systematical summary on the method for adjusting dual induction log zero is given in detail according to the abnormal phenomenon. In the end, some suggestions on the field adjustment of dual induction log zero and its field calibration are proposed.
