| 摘 要： | 介绍了讨论了复电阻率法探测油气藏的基本原理，提出了用复电阻率法探测油气藏时，尤其是在良导电覆盖层地区，分离激电和电磁响应，获取剩余电磁资料的一种有效技术。指出复电阻率测量剖面附近的套管会引起明显的视电阻率，激电和剩余电磁资料异常。为了去除或减弱这种干扰异常，提出了一种校正方案，最后，对复电阻率法在研究地区的应用进行了介绍和讨论。

| Abstract: | The principles of using complex resistivity (CR) method for hydrocarbon detection are introduced and discussed. An effective technique is developed for separating IP and EM responses and acquisition of residual electromagnetic (REM) data in CR data processing in hydrocarbon detection, especially in areas with high conductivity overburden. It is shown that the well casings in the vicinity of the CR survey will produce an effective resistivity, IP and REM anomalies. For removing or decreasing the interference anomalies, a correction scheme is proposed. Finally, the application of CR survey for hydrocarbon detection in the study area is presented and discussed. |
