The Cambodian Kampong basin located in the east Gulf of Thailand, which is a Meso-Paleozoic basin and located in the east of the paleo-Thetis suture zone. The basin that recognized as a intraplate-craton basin until the Permian, became the intracontinental rift basin after the late Triassic, as the tectonic movement. At present, the exploration degree in this basin is very low. The hydrocarbon research doesn't carry out before, thus seismic data and well log data are lack. In order to analyze and evaluate the hydrocarbons potential, we integrated the seismic and high accuracy satellite gravity data (sample density: 0.02°×0.02°), to calculate Bouguer gravity anomaly, the gravity vertical second-order derivative and the gravity level total gradient anomaly, According to the gravity field theory and the global gravitational field model(EGM96).Finally, Based on seismic constrained gravity inversion and interpreted integration, the research forecasts the basement depth, analyzes the fault system and divide the tectonic unit, finally indicated the direction for the next step exploration research.
