Abstract: Petroleum seismogeology is one of the highly integrated system sciences. With rapid development in the past decades, this discipline has been introduced practically into almost every field of petroleum exploration and domain of oil-gas field development. Thus, petroleum seismogeology has been a newly rising marginal discipline with great practicability and vitality. The paper briefly introduces recent advances of this discipline in structural interpretation, sedimentology, reservoir characterization, development seismology and non-conventional hydrocarbon seismic exploration, and discusses relevant technical issues. It is proposed that petroleum seismogeology has entered a new era in techno-methodology, which refcected by new working flows occurring in techniques of seismic interpretation, geological structure modeling running through the whole procedure of interpretation, popularization and application of depth-domain interpretation and full 3D volume interpretation.
