Abstract:More than 20 years' exploration has proved that in Taikang-Gulong area there exist oil-gas resources which are in structural,lithologic and structural-lithologic combination traps respectively.However,con-ventional seismic exploration can hardly determine reservoir extent because structure size and sand-bed thickness are small,thin sand beds being usually interbedded in mudstone beds.In recent years,high-resolution seismic exploration was done in this area.The dominant frequency of target reflection has been increas-ed from 25Hz to 40~50Hz,which provides good raw data for lateral reservoir prediction.Sand body and oil or gas boundaries were predict-ed using amplitude information,velocity analysis along a formation,wave impedance section and seismic lithology modeling(SLIM).Quito good result has been obtained.
