时频电磁法在牛驼镇凸起油气资源勘查中的应用
Application of the time-frequency electromagnetic method in hydrocarbon exploration in the Niutuozhen uplift
摘要
Abstract
The time-frequency electromagnetic(TFEM)method,a new electromagnetic exploration technique,emerged at the beginning of this century,followed by its introduction and development in the hydrocarbon exploration field.It combines the advantages of both frequency-domain and time-domain electromagnetic techniques,offering a higher resolution and more accurate imaging of underground structures under complex geological conditions.It plays an important role in energy resources exploration.This paper presented the appli-cation of the TFEM method in the hydrocarbon exploration in the Niutuozhen uplift.The results indicate that the hydrocarbon reservoirs in this uplift exhibited low-resistance and high-polarization electromagnetic response from the upper layers.Conversely,they showed the high-resistance and high-polarization electromagnetic response from the internal.Based on the TFEM abnormal response patterns,five play fairways were delineated in the Niutuozhen uplift,which were basically consistent with known drilling data.This study provides a solid foundation for the hydrocarbon development and utilization in this area.关键词
