This paper explores the correlation between different microstructural characteristics of porous sedimentary rocks and the flow properties of a Newtonian infiltrating fluid. Preliminary results of displacement propagator measurements of brine solution flowing through two types of sedimentary rock cores are reported. The two types of rocks, Bentheimer and Portland, are characterized by different porosities, pore-size distributions and permeabilities. Propagators have been measured for brine flow rates of 1 and 5 ml/min. Significant differences are seen between the propagators recorded for the two rocks, and these are related to the spatial distribution of porosity within these porous media.
本文探讨了多孔沉积岩不同微观结构特征与牛顿渗流流体流动特性之间的相关性。报告了盐水溶液流经两种沉积岩芯的位移传播器测量的初步结果。这两种岩石,即本特海默岩和波特兰岩,具有不同的孔隙率、孔径分布和渗透率。已测量了1毫升/分钟和5毫升/分钟盐水流速下的传播器。两种岩石记录的传播器之间存在显著差异,这些差异与这些多孔介质内孔隙率的空间分布有关。
