Zusammenfassung: | The invention relates to the technical field of oil and gas resource exploration and development, and discloses an electromagnetic phase simulation earthquake method for complex structure and fracture identification, which comprises the following steps: calculating a detection depth, and encrypting a depth value and an apparent resistivity value in a depth direction; the actual altitude of each data point is calculated according to the depth value of the detection depth, and an electrical difference reflection coefficient is calculated by analyzing the calculation principle of the reflection coefficient in seismic exploration; selecting set parameters to calculate a Ricker wavelet; carrying out convolution on the Ricker wavelet and a reflection coefficient to generate a simulated seismic profile map; and using the simulated seismic profile map to identify construction and fracture information. According to the electromagnetic phase simulation earthquake method for complex structure and fracture recognition, i |
