摘要：
The time-frequency electromagnetic(TFEM) method is a controlled source electromagnetic method developed for oil and gas exploration, which can detect deeply-buried targets. Based on a real geoelectric model and the noise analysis in the Area Q, the characteristics of electromagnetic anomalies caused by geological targets are analyzed by 3D modeling, and the acquisition design is comprehensively studied. A receiving system design with equal-waist trapezoidal region electrode distribution and receiving signal balance and a transmitting system optimal design for target anomaly contrast analysis are proposed. At the same time, based on the single-noise analysis of the stacking times, an excitation design method for excitation period setting and stacking time is also proposed. © 2019, Editorial Department OIL GEOPHYSICAL PROSPECTING.
