Lithologic reservoir exploration has become one important oil-gas exploration target in Dongying Sag. Source rocks developed well in the third and fourth members of Shahejie Formation in eastern Dongying Sag, which supplied sufficient hydrocarbon resources for lithologic traps. The exploration practice indicates that this area developed delta front slump turbidite fan and deep-water turbidite fan, as well as transportation systemand favorable mudstone seal. The source-reservoir-cap assembled well in space and time, which provides favorable conditions for the forming of sand lens lithologic reservoirs and structural-lithologic reservoirs.
Key words: reservoir characteristics; diagenesis; seismic response
