| 摘 要： | 随着测井仪器技术的不断进步，对数据采集精度的要求越来越高，这使得数据传输误差大的难题越来越突出。文章通过建立随机信号模型，用特定的噪声调制使测井中有用信号发生随机共振，抑制无用信号，为从理论上解决测井中数据采集、传输信号误差问题提供有益的尝试。

| Abstract: | The difficult problem of the petroleum logging are mainly in two aspects: the data acquisition and the data transformation. With the development of the technology in logging instrument. More and more precision logging date are required. At the same time the errors in date transformation are more paid attention to. This paper introduces the model establishment of the random signal, that is, the useful logging signal takes place the random resonance through use of the particular noise to repress the useless signal. the signal error can be resolved in theory using this model. |
