摘　　要：在不同发射频率和多收发距情况下,进行二维水平板状储集体正演计算,将模拟结果转换至共收发距域,提出针对此种模型研究归一化异常的方法。研究表明,海洋CSEM法对单一水合物储集体具有较好的横向分辨能力,将海洋CSEM资料转换至共收发距域可使电磁响应横向分辨能力的分析更为直观,归一化异常可作为定量衡量横向分辨能力的重要依据。Under the circumstance of different frequencies and multiple transceivers distance,the twodimensional horizontal plate forward reservoir simulation was carried out.The results were converted to the common transceiver domain,and then a model is proposed for the study of abnormal normalization method.Studies show that marine CSEM method for single hydrate reservoir has high lateral resolution.Marine CSEM data will be converted into a common transceiver domain,the analysis of electromagnetic response of the lateral resolution can be more intuitive,the anomaly normalization can be used as important criteria for quantitative measurement of the lateral resolution.
