摘要: 针对塔河油田缝洞型油藏非均质性强的特点,将其储集层抽象成渗透率突变的地质模型,并应用油气渗流理论推导出了部分打开缝洞型底水油藏的水相分流量方程,同时对分流量曲线的影响因素进行了分析。分析表明,该方程可准确描述不同储集层条件、不同生产压差下的含水率变化规律。该理论的建立为缝洞型底水油藏开发动态分析和预测提供了依据。

Abstract: The fractured-vuggy reservoir in Tahe oilfield is characterized by strong heterogeneity. This paper presents a geologic model for reservoirs with varied permeability in Tahe oilfield, including the water fractional flow equation for such a reservoir after partial perforation derived by oil-gas flow theory, and analyzes the impacting factors on the fractional flow curves. The study shows that the derived equation can be used to precisely describe the water cut variations under the different reservoir conditions and the different producing pressure differentials. The proposed theory could be as a guide for production performance analysis and prediction of other fractured-vuggy reservoirs with bottom water.

Key words: Tarim basin, bottom-water reservoir, fractional flow equation, water cut
