| 摘 要： | 在二维地层模型条件下,应用有限元方法模拟了双侧向模式的复电阻率测井仪器在不同频率下的响应,结果表明当频率很低时,复电阻率测井的响应接近双侧向测井的响应;随着频率的提高,复电阻率测井的响应幅度降低。当地层具有一定的频散效应时,可以利用不同频率下的复电阻率测井响应直观地区分油水层

| Abstract: | Complex resistivity well logging (CRWL) is a new well logging method for differentiating and evaluating the saturation of rock formation through its frequency dispersion character. The current tool used in the field is actually the modified dual laterolog tool. The tool can be used to measure deep and shallow laterologs at two different frequencies. The ratio of low frequency (0～200Hz) to high frequency (1～20k) is used to evaluate the formation. The bigger ratio means the higher oil saturation. CRWL has bee |
