Abstract The time-frequency domain electromagnetic (TFEM) sounding technique can directly detect the oil and gas characteristics through the anomaly of resistivity and polarizability. In recent years, it has made some breakthroughs in the hydrocarbon detection. In order to predict the petroliferous property of the Ili basin, The TFEM was carried out. According to the geological structure characteristics of the study area, a Two-Dimensional layered medium model is constructed, and the forward modeling is carried out. We use the forward modeling results to guide the field construction and ensure the quality of the field data collection. We use the model inversion results to identify and distinguish the resolution of the geoelectric information, and provide a reliable basis for data processing. Based on that, the key technologies such as 2D 2-D resistivity tomography imaging inversion, polarimetric constrained inversion have been developed, and we obtained the abundant geological and geophysical information. Though the analysis of the electrical logging data in the study area, the characteristics of TFEM anomalies of the hydrocarbon reservoirs in the Ili basin are summarized. And more, the oil-gas properties of the Permian and Triassic layers have been predicted, and the next favorable exploration targets have been optimized.
