从地震资料研究琼东南盆地松东地区流体势特征

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。综合本区地震剖面、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。

Fluid Potential Character Inferred by Derived Seismic Data in Songdong Area, the Eastsouth of Hainan Basin

Fluid potential analysis system (FPAS) is used here to study the distribution character of underground fluid potential and pressure, which can get over the limitation of imperfect drilling data to effectively predict and evaluate oil and gas resources. The application of this system has been proved successful in the east Nanhai Field. Fluid in formation is controlled under the two fluid system-compaction fluid and gravity fluid. After comprehensive analysis, we can find the most prospective formation for exploration.
