Abstract：Many igneous rock areas are rich in oil gas resources.The special geological features and complex seismic wave field restrict the proceeding of exploration.This paper proposes a few processing approaches for this kind of data.By analyzing the igneous data characteristics in energy,frequency and velocity of Jiyang Depression in Shengli Oilfield,we simulate wave field frequency dispersion and low-pass filtering and other features,and illustrate igneous area-oriented seismic data surface wave processing,energy compensation,dominant frequency band weighting,velocity analysis and prestack time depth migration joint imaging technology.We demonstrate also our approach application results in Shengli Oilfield.We recognize that some processing methods for this kind of data merit further development in the subsequent exploration.
