Eastern Pre-Caspian Basin is one of the most abundant area in the basin.The paper analysis the salt-related tectonic evolution of the eastern region and its relationship with petroleum accumulation,think that salt tectonic evolution played an important control effect on the formation of hydrocarbon accumulation.Affected by the evolution of salt-related tectonic,the main source rock basin in eastern subterranean salt are the Lower Carboniferous and Lower Permian;salt layer system is high quality carbonate reservoirs;salt layer is a regional cap rock;salt-related structural traps and fault syste...
