摘要
针对塔河油田奥陶系缝洞型碳酸盐岩油藏特点,结合渗流和流体力学知识,建立了缝洞型油藏渗流、管流和平板径向流耦合数学模型,揭示了储集体内流体的流动规律。对一维流动、弹性开发和注水开发进行了模拟计算。模拟结果表明,弹性能是封闭性油藏主要的驱动方式,而注水开发油藏含水率会呈台阶式增长,模拟结果与实际开发效果相符。
Considering the characteristics of fracture-vuggy carbonate reservoir of Ordovician system in Tahe Oilfield, a model coupling seepage, pipe flow, and radial flow for fractured-vuggy carbonate reservoir was developed. This model captures the flow in pay zone. One-direction flow, elastic development and waterflooding development were simulated. The result shows that elastic energy is the main energy in elastic development reservoir, water cut will increase in water flooded reservoir. The results match the actual production.
