Abstract: Forward modeling with Zoeppritz equation and AVO hydrocarbon detection require the accurate reservoir properties. However, it is unlikely to obtain them with high accuracy outdoors. Laboratory simulation test in cores can solve this problem. In this study the elastic parameters are measured in the drilling ores from the pilot area under simulated subsurface temperature and pressure, and then used to carry out forward modeling with Zoepprit equation to test the hydrocarbon indication of reservoir and to conduct special AVO processing. It can be used as a supplementary tool for hydrocarbon detection seismic data.
