Abstract: Under the circumstance of different frequencies and multiple transceivers distance, the two-dimensional 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.
