摘要
基于井间电磁测井,在层状介质环境中恒定发射磁矩,测试随发射频率、发射和接收器距离变化,接收器电压信号的幅值变化。测试分析数据表明,测试结果可靠,数据可清晰地指示出层界面的变化;接收信号的幅值随发射频率增高而衰减,但是分辨率升高。对比数值模拟计算结果,二者响应规律基本一致。该研究有助于井间电磁测井仪探测器设计,加快仪器研发进度。
In order to test the cross-well electromagnetic logging response characteristics under the condition of magnetic induction in layered media,we use the receiving probe to measure different transmitting frequencies or different distances.The data can mark the different medium clearly.The amplitude of test data decreases with the increase of transmitting frequency,but the resolution is increased.The characteristics of test data agree well with the result of the forward analysis.This study speeds up progress of research and development of cross-well electromagnetic logging tool.
