Abstract:Mudstone interlayer of Jintan rock salt gas storage constitutes a risk in cavity construction.How to identify the mudstone interlayer thus becomes a key problem in exploration.The mudstone interlayer distribution in this region is complex and the quality of seismic data is poor because of the influence of plasticity.As a result, it was hard to identify the mudstone interlayer accurately if only seismic data are used.Therefore,the features of seismic response and logging response of mudstone interlayer were analyzed,also the authors made a connection between gamma curves and seismic information,and carried out multi-parameters inversion.On such a basis,planar and special distribution features of mudstone interlayer were predicted.The application of practical data shows that multi-parameter lithologic seismic inversion can effectively reflect the features of mudstone interlayer variation.
