三维感应测井仪在井下工作时的环境温度与地面温度差异很大，而温差过大会对仪器天线的收发信号和电路信噪比均产生明显影响，导致仪器测量的地层参数误差较大。通过分析天线和电路的温度影响因素，文章讨论了一套三维感应测井仪测量数据温度漂移的校正方法。

The environment temperature of three-dimensional induction logging tool works underground is very different from ground tem-perature. The difference in temperature will change the transmit-receive signal of the antennas and the SNR of the circuit,which leads to the bigger measurement error of formation parameters. By analyzing the temperature influence factors of antennas and circuits,this paper dis-cusses the correction method for the temperature drift of measurement data of three-dimensional induction logging tool.
