Abstract：Biohermal reservoir is a typical lithologic reservoir, which makes the seismic exploration of bioherm very difficulty since the multiplicity and complexity of its geologic feature.In view of Permian biohermal geologic feature and data cases in eastern Sichuan area, the paper, taking biohermal gas reservoir as a studied object and starting from the analysis of feature of seismic response in the known wells, built up discriminating mode of bioherm and biohermal reservoir by multiple seismic special processing and interpretation approaches such as analysis of seismic reflection structure, waveform-categorized processing in neural network, analysis of seismic attributes, 3-D visualization interpretation and seismic multi-parameter inversion etc., forming purposeful necessary techniques of seismic exploration.Among these techniques, the seismic multi-parameter inversion taking the gamma, compensated neutron and acoustic curves as objective curves is very effective on prediction and evaluation of bioherm.
