摘要
油气的运移、聚集与地下水动力场的形成与演化密切相关.随着沉积盆地的形成与演化,地下水动力场也有形成、发展和消亡的过程.讨论鄂尔多斯盆地地下水动力场的形成与演化,推断其油气的分布规律:大气水下渗——向心流处为水区,天然气离心流区为气区,越流天然气漏失区对应于气水共存过渡区.
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 oilgas in the Ordos Basin by discussing the evolution of the hydrodynamic field, and consequently to analyze the history of the migration and accumulation of oilgas in the Ordos Basin. The downpenetrating 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 gaswater transition zone. The conclusion has great importance to resource evaluation and the decisionmaking of exploration.
