Abstract

Abstract: The design methods for oil-water two-phase migration physical experiment model with the light etched technique were intro-duced.The determination of the geometric parameters,topology structure and the quantitative macroscopic parameters such as permeability were discussed.The light etched model for physical simulation of two-phase migration in fracture network was made successfully.The experiment results show that the wider fracture system has significant flow shield effect on narrow fracture system.In some cases,the migration velocity of more viscous oil is higher than that of relatively light oil,which indicates the complicate process of oil migration in fractured media.

Key words: fractured media, oil and gas migration, light etched model, physical experiment

摘要： 系统地介绍了裂缝介质中油水两相运移光蚀刻物理模拟实验所采用的实验模型设计方法、应考虑的因素、模型几何参数确定、拓扑结构、模型渗透率等宏观特征参数的定量化以及流体参数的选择方法.实验结果表明:①宽缝对窄缝具有极强的流动屏蔽作用,窄缝在油气运移中几乎不起作用;②在运移动力方向与渗透主方向垂直的情况下,当原油粘度达到一定数值时,沿驱替方向上运移的速度反而会更快一些.
