Abstract

The research means and methods of reservoir geochemistry, reservoir geology and sedimentology are applied to discuss the hydrocarbon sources, migration mechanism, dynamics and accumulation pattern of Chang 9 reservoir in Jiyuan area. The result shows that the crude oil of Chang 9 reservoir comes primarily fromthe high-quality hydrocarbon source rocks ofChang 7 reservoir, ofwhich the hydrocarbon migrated downward and accumulated in Chang 9 reservoir. The main dynamic ofChang 7 hydrocarbon migrating to Chang 9 reservoir is mainly fromthe abnormal high pressure of Chang 7 hydrocarbon source rock hydrocarbon pressurization and excess pressure difference between Chang 7 and Chang 9 reservoir. The vertical superposition and lateral connecting sand bodies and the fractures formed in the regional tectonic activity are the favorable migration path for connectingChang 7 high-quality hydrocarbon source rocks with Chang 9 reservoir.
