摘要

油藏中流体所具有的能量决定流体流动方向

为研究缝洞型油藏流体能量分布规律

建立了缝洞型油藏流势理论模型

确定三维流体势表征方法。通过单洞底水、单洞边水、双洞底水、双洞边水4种典型缝洞结构的机理模型研究流势变化规律

并确定了5种影响流势调整效果的主控因素

最终结合流势分析技术开展了剩余油挖潜研究。结果表明：单洞底水模型进行流势调整

生产井受效最好;模型水体倍数为决定性因素

水体倍数小于10倍时调流势效果好;排液量越大

对于生产井控水效果越好。提出的数学模型能够真实地反映出地层中流体能量分布变化规律

结合流势分析技术提出了挖潜方案

应用于现场效果明显。

Abstract

The energy of fluid in oil reservoir determines the direction of fluid flow. In order to study the energy distribution of fluid in fractured-vuggy reservoirs

a theoretical model of fluid potential is established

and the 3D fluid potential characterization method is determined. The mechanism models of four typical fractured-vuggy structures

single hole with bottom water

single hole with side water

double hole with bottom water and double hole with side water

are use to study the change rules of flow potential

and five main control factors affecting the flow potential adjustment effect are determined

finally

the research on potential tapping of residual oil was carried out in combination with flow potential analysis. The results show that the adjustment of flow potential for the model of single hole with bottom water make the production wells work best. The model’s water multiple is the decisive factor

and the flow potential regulation effect is better when the water multiple is less than 10 times. The greater the discharge

the better the effect of water control for production wells. The proposed fluid potential solving model of fractured and cavern reservoir can truly reflect the changing rules of fluid energy distribution in the actual formation.
