The formation and evolution of the hydrodynamics play a great role in the migration and accumulation of oil and gas. Along with the formation and evolution of the sedimentary basin, the hydrodynamics also has its process of formation, development and dying out finally. It was made to try to investigate the migration and accumulation of oil-gas in the Ordos Basin by discussing the evolution of the hydrodynamic field, and consequently to analyze the history of the migration and accumulation of oil-gas in the Ordos Basin. The down-penetrating and centripetal flow area of meteoric water is the water zone, the area of centrifugal flow is the gas zone and the discharge area by cross formation is the gas-water transition zone. The conclusion has great importance to resource evaluation and the decision-making of exploration.
