Abstract:Three sets of salt-bearing cyclothem in deep lacustrine facies are developed in Es'formation in the north of Dongpu depression, which led salt rock to flow and deform because of buried depth and action of structural force in the latter and then formed many salt-related structures or lithologic traps.Since salt rock is always accompanied by the clay in deep lacusrine facies,the salt-developed area is the developed.area of hydrocarbon source rock and also the developed area of salt structures and salt traps.Since the area has the superior conditions of source area,reservoir,cap formation,trap and reservation,the area always is our studied key target.The paper introduced a variety of salt-deformed-related structure and trap types ,characters of seismic reflection Erom salt and identified methods,and discussed control action of salt and salt structure on oil-gas.
