摘要

摘要: 在静水条件下,利用填装玻璃微珠的管状玻璃管模型,观察油在饱和水的孔隙介质内的渗流规律,通过选择与运移动力直接有关的参数,观察到油在孔隙介质模型中3种不同的运移模式.根据毛管数和Bond数综合分析各个因素间的关系及其对运移模式的表征,在运移模式图上分出界线明显的3个区:平稳推进区、毛管指进区、优势路径区.认识到在输导层物性确定条件下,单纯浮力以及相对较小的驱动力是油气形成优势二次运移路径的重要因素.

Abstract: Using porous media model in columns packed with glass beads under hydrostatic condition,the principles of hydrocarbon migration in porous media saturated with water were observed.Different geological factors associating with displacement forces have been tested.Migration front presented three patterns.The relationship among various parameters and its effect on migration pattern were analyzed according to capillary number and Bond number.The patterns include stable advancement,capillary finger and preferable migration pattern.Given the properties of carried beds,the preferable pathway of hydrocarbon migration depend on the single buoyancy or lesser displacement forces.
