流体势分析研究及应用

Fluid Potential Analysis Study And Application

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。本文主要介绍了流体势的计算方法 ,具体分析了琼东南盆地松东地区油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 :油气是从高势区向低势区运移的 ,并在位于油气运移路径上的低势圈闭中聚集成藏 。

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 mainly introduces the calculational method of Fluid potential and specially analyses the oil potential section distributing characters in the Songdong area of Qong southeast basin, thus shows the area's oil and gas migration and accumulation systems. It concludes that oil and gas migrate from low potential area to high potential area, and accumulate in the low potential traps which is located in the path of oil and gas migration, therefore, the low potential areas are the advantaged areas of the reservoir development.
