Abstract: The tight sandy conglomerate reservoirs in Bonan area of Jiyang Sag,Bohai Bay Basin are affected by gypsum rock,complex superimposition relationship and heterogeneity,which results in shield interface in the seismic signal. Conventional reservoir prediction methods can not meet the needs of accurate reservoir prediction,seismic identification is difficult and the reservoir is also difficult to describe. The nail-type wavelet and compressed sensing technology were used to remove the strong shield interface,highlight the seismic response characteristics of sandstone in the target layer,effectively improve the prediction ability of sandstone. This method can provide strong support for the next exploration deployment.

Key words: removal of shield, nail-type wavelet, compressed sensing, seismic response
