| 摘 要： | 为了更好地开发塔河油田缝洞型底水油藏,本文针对塔河油田缝洞型底水油藏非均质性强的特点,提出了缝洞型底水油藏见水时间预测方法,在研究过程中,将储层抽象成为渗透率突变地质模型,定义渗透率突变系数和区域半径比,并假定①稳定流动;②忽略毛管力,油、水间有明显的界面;③油、水的密度和粘度为常数,在此基础上给出了塔河油田缝洞型底水油藏见水时间的预测公式,并分析了渗透率突变系数和区域半径比在油井钻遇不同部位情况下对该类型油藏油井见水时间的影响。

| Abstract: | On the basis of thinking about the intensive nonhomogeneity of fractured-vuggy reservoir with bottom water of Tahe oilfield,take the reservoir as geological model of mutation permeability,define the coefficient of mutation permeability and ratio between radius of regionalities,make use of Dupuit formula to deduce calculation method of critical flow rate for fractured-vuggy reservoir with bottom water.And analyze the influences on critical flow rate by the coefficient and the ratio at different situations of... |
