【摘要】 在油田开发过程中,准确地估算剩余油饱和度及其分布对于估算一次采油和二次采油的可采储量具有重要意义,研究的核心是剩余油饱和度的精度。目前,确定剩余油尚无一种最佳的方法,通常应用多种方法研究,以便达到提高剩余油饱和度精度的目的。各种方法确定的剩余油饱和度反映不同范围内剩余油饱和度的分布。在总结了开发地质学、地震、测井、岩心分析、物质平衡、水驱特征曲线、数值模拟法等剩余油的研究方法后,对各种方法的适用范围进行了比较。更多还原

【Abstract】 In the development process of oil fields,estimating the residual oil saturation and its distribution correctly is of great significance for estimating the recoverable reserves of first oil recovery and secondary oil recovery.The core of researching remaining oil saturation is accuracy.At present,there is no best way to determine the residual oil,and in order to improve the accuracy of residual oil saturation various methods were usually applied.The residual oil saturation determined by various methods reflects the remaining oil saturation distribution in different scope.The research methods including the development geology,seismic,well logging,core analysis,material balance,water-drive characteristic curves,numerical simulation,and compares their characteristics and application limitation are summarized.更多还原
