The lithologic-stratigraphic reservoirs of Shahejia Formation in Tiejianglu slope belt have complex oil/ water relationship. The prestack seismic data with relative amplitude preservation contain more information about lithology and fluid than the poststack seismic data. Therefore, the prestack seismic data can be used for hydrocarbon detection. The primary application of prestack seismic data of Aki & Richards and Shuey approximate expressions based on Zoeppritz equation in hydrocarbon detection is introduced. AVO forward modeling is conducted to define fluid-corresponding AVO abnormity, then to identify AVO abnormity across well point trace gather, and finally to interpret AVO multi-attribute body, thus to find abnormal hydrocarbon distribution zones and guide the exploration deployment in the study area.
