SEDIMENT LOGICAL INTERPRETATION FOR SEISMIC INVERSION RESULTS

Research of sedimentary characteristics is very important in the process of reservoir exploration and development.Seismic inversion technology is combined with sedimentological principle to characterize sedimentary features,which is the most effective method to carry on sedimentary microfacies research based on seismic data.Seismic phase-controlled concept is br ought into nonlinear random inversion to make inversion results approach geological features.Guided by seismic sedimentology theory,combined with seismic facies analysis technique,based on high-accuracy seismic inversion results,sedimentary features are interpreted in well area C15 of CZ depression as a exploratory application,which has higher reliability than sedimentary features characterized directly on seismic section and yields better fine sedimentary microfacies characterization.
