摘要
采用先进的可视化气驱物理模拟研究手段,设计出直径为6 cm,长度为60 cm的高温、高压钢管填砂模型,模拟地层条件下枯竭油藏改建储气库注采运行;分析了储层物性对储气库库容的影响;测定多次注采后油气水饱和度的变化,研究多次循环注气、采气过程中的气液渗流特征及对注采气能力的影响。研究结果表明:枯竭油藏改建储气库多次注采,既能提高原油采收率,又能增加储气库库容。
By air-drive physical simulation, the model for high temp650 centimeters.It is used to simulate the process of gas injection-production of gas storage in depleted oil reservoirs, to analyze reservoir characteristics on storage capacity, and to study the effect of injection-production times on injection-production capability.Results show that frequent injection-production can increase not only oil recovery factor but also storage capacity.
