Crosswell Seismic Migration Based on the Upward Reflection Wave
The frequency of the Crosswell seismic data is high,using it after processing we can get high resolution imaging result the article based on the wave equation method to realize the migration of the crosswell data,the method uses the wave field downward continuation based on accumulating step by step and the Fourier finite difference operator to achieve the pre-stack migration of well data. It has strong adaptability to the medium which has strong variable transverse velocity,and has good migration quality,high resolution,it can better accomplish the migration of the minor scale feature,for example the minor fault,minor block fault and so on. Testing on model and actual data processing shows the validity and the practicability of the method.
