There is a series of achievements about salt tectonics both at home and abroad. This paper points out that fluid in the tectonics development of the important role of salt, which is based on previous studies and the developmental characteristics of salt tectonics in Dongying sag. It contains a lot of salt-gypsum and salt-gypsum formations. This paper analyzes the characteristic of the salt tectonics according to the core, logging and seismic data. Abnormal high pressure created by salt-gypsum dehydration in stratum, high pressure can be used as a dynamic force fluid flow upward and this contributes to hydraulic fracturing in the overlying strata and can drive the salts material in the process of fluid upwelling upward movement. This paper proposes that salt-gypsum dehydration has an important influence on the formation of the salt tectonics. Based on the effect of salt-gypsum dehydration and overpressure fluid, the history of model of member 4 of Shahejie Formation salt diapir in Dongying sag is established according to seismic cross-section and logging data. Salt tectonics is analyzed during the migration of fluids in the process of development, salt-gypsum dehydration effect in early and mid-salt tectonic development important role.
