琼东南盆地松东地区水势分布研究

Study on Fluid Potential Distribution in Songdong Area of Qong Southeast Basin

利用流体势分析系统 (简称FPAS)研究地下流体势及压力分布可克服井资料不系统的局限性 ,有效的进行油气资源的预测评价。本文具体分析了琼东南盆地松东地区水势在剖面上的分布特点 ,以揭示该地区的油气运移、聚集规律。研究结果认为 :该地区水势分布特征、运移与油气势的分布、运移基本一致 ,为油气的运移提供动力 ;

Fluid potential analysis system (FPAS) is used to study the distribution character of underground fluid potential and pressure, which can get rid of the limitation of not perfect drilling data and effectively make the prediction and evaluation of oil and gas source. In the article, it specially analyses the water potential section distributing characters in the Songdong area of Qong southeast basin, thus shows the area's gas migration and accumulation systems. It concludes that water potential distributing characters and migration are similar to gas distributing characters and migration in this area, and water potential provides dynamics for oil and gas migration; The study of water potential distributing characters is helpful to the study of oil and gas distributing.
