Abstract:Time-frequency electromagnetic (TFEM) method plays an important role in oil and gas exploration. In addition, model accuracy in data inversion has a great impact on the inversion accuracy. In order to effectively reduce the non-uniqueness of inversion and improve the inversion accuracy, it is necessary to make full use of existing data for accurate modeling. Based on the actual exploration data of the Northern Junggar Basin, this paper uses Gaussian distribution to statistically analyze the electrical logging data of the study area and obtains characteristic electrical data of each stratum, such as the mean value of resistivity and deviation, so as to propose a layered electrical modeling method for the upper and lower structural layers and different strata in the study area. Through the rock dispersion test of igneous greservoirs, the dispersion characteristics of igneous rock with different oil and gas saturation in the study area are obtained. Furthermore, according to the TFEM oil and gas detection results and the oil and gas information during drilling, an identification template for oil and gas electromagnetic attribu-tes is established. The case shows the resistivity and polarization profiles obtained through layered modeling and TFEM inversion, as well as the analysis and interpretation of profiles, have identified favorable targets for hydrocarbon exploration. The modeling method and hydrocarbon target interpretation idea in the paper can provide a valuable reference for hydrocarbon reservoir evaluation in similar areas.
