| 摘 要： | 本文采用数字滤波技术,研究了电阻率测井的理论曲线计算和Ra曲线的环境影响校正,并对影响数字滤波效果的因素进行了分析。结果表明,用数字滤波新技术进行环境校正,提高了校正质量,比传统的图版校正方法有明显优点。文中采用数字滤波方法绘制的Ra理论曲线,证明所推导的数学模型是正确的。

| Abstract: | In this paper the theoretical curves of the resistivity logs are calculated and the environment corrections to the apparent resistivity Rα discussed, using the digital filter technique, and its effects analysed. The result indicates that the new digital filter technique is superior to the conventional charts in the environment corrections. It is also demonstrated that the mathematic models drawing Rα-curves using the digital filter method are correct. |
