摘要:
为了更好地了解真实岩心微观渗流过程中的渗流规律和流体分布特征,研制了一套新的微观可视化驱替观测装置。利用真实礁灰岩岩心制作岩心薄片模型,采用可视化岩心夹持器模拟水驱油过程,选取具有代表性的三组模型实验。实验观察发现,基质对岩心水驱的影响很大,不能忽略,同时观察到流体在岩心呈现明显的三维流动状态,这将导致通过面积计算得到的孔隙度、饱和度、采收率等数据存在误差,误差大小与孔隙组成和分布有关。
Abstract:
In order to better understand the seepage law and fluid distribution in the process of microscopic seepage,a set of new visualization observation instrument for micro displacement was developed.The core slice models were made by using the real reef limestone cores.And then the water-flooding process was simulated in three groups of representative models selected through adopting the visual core gripper.Experimental observation revealed that the matrix has great influence on core water-flooding.Meanwhile obvious three-dimensional flow was observed in the cores.The phenomenon can result in data error of porosity,saturation and recovery rate,etc.obtained by area calculation.The error magnitude is related to the composition and distribution of pores.
