| 摘 要： | 地层流体受两大流体系统的控制：压实流和重力流。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，有效地进行油气资源的预测评价。由于琼东南盆地地质务件极其复杂，海洋油气勘探程度很低，勘探成本高，石油地质研究水平也比较低，分析认为区内有巨大的油气资源前景，但油气运移方向和路程均不清楚。用地下流体力场和势分析的方法可以统一处理和定量解释油气的运移和聚集规律，明确预测油气运移的主通道，确定有利的油气勘探靶区，显著提高钻探成功率。综合本区剖面、平面流体势及压力特征，结合其他有关地质资料，找出最有利的勘探目的层位。该方法在琼东南盆地松东地区的应用，取得了良好的效果。

| Abstract: | Fluid potential analysis system (FPAS) is used here 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 resources. As the geological condition of basin is very complex , the level of petrogeology study in this basin is low. We all think this basin prospects well .But the way and orientation of migration of oil and gas is not distinct. Fluid potential analysis system is used here 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 resources. The application of this system has shown a success in the east of Nanhai Field. |
