Abstract:Based on the seismic data in A Block in Daqing Oilfield,the cross-well seismic data acquisition method is introduced in this paper.With the study to the difficulties of data processing and the corresponding processing methods,such as cross-correlation stack,wave field separation,direct wave tomography and reflection image,a set of practical processing methods are summarized.After merging the cross-well seismic sections of three wells,it can be found that the joints of the cross-well seismic section are not obvious and the seismic events are continuous,showed the relatively higher resolution and signal to noise ratio and demonstrated the feasibility of the processing method.
