Transport and acoustic measurements have been conducted on fifteen rock samples collected from central Lebanon to characterize the rock properties and to assess the impact of lithology, pore types, pore sizes, and textural parameters on the storage capacity and elastic characteristics. The spontaneous imbibition of selected samples was examined by detecting the moving capillary front across a sample. The coefficient of capillarity derived from the spontaneous imbibition is positively correlated with permeability. Seismic velocities in the studied rocks vary widely and are positively correlated with the rock density. Matrix-supported rocks with a larger proportion of micropores have lower seismic wave velocities, whereas the grain-supported carbonates exhibit low to moderate porosity and higher acoustic velocities. The elastic properties of the studied carbonates indicate a granular, rather than a crystalline, texture for the majority of the studied rocks. The widely variable elastic behavior of basically carbonate rocks implies that seismic reflection profiles in carbonate sequences may contain seismic reflections that do not result from non-carbonate intercalations but which result mainly from variable porosity, pore types, and shapes in the carbonate rocks themselves. This study provides important information on the textural, petrophysical, and elastic properties of carbonate rocks which are crucial for the assessment and understanding of the seismic reflection sections in subsurface carbonate reservoirs.

已经对从黎巴嫩中部收集的15个岩石样品进行了运输和声学测量，以表征岩石特性并评估岩性，孔隙类型，孔径和质地参数对储层容量和弹性特征的影响。通过检测样品中移动的毛细管前沿来检查所选样品的自发吸收。自发吸收产生的毛细血管系数与渗透性呈正相关。所研究岩石中的地震速度变化很大，并且与岩石密度成正相关。具有较大微孔比例的基质支撑岩石具有较低的地震波速度，而颗粒支撑碳酸盐具有较低至中等的孔隙度和较高的声速。研究的碳酸盐的弹性性质表明大多数研究岩石具有颗粒状而不是结晶质感。基本上碳酸盐岩的弹性变化很大，这意味着碳酸盐岩层序中的地震反射剖面可能包含不是由非碳酸盐岩插层引起的地震反射，而是主要由碳酸盐岩本身的孔隙率，孔隙类型和形状变化引起的。这项研究提供了有关碳酸盐岩的质地，岩石物理和弹性特性的重要信息，这对于评估和理解地下碳酸盐岩储层的地震反射剖面至关重要。基本上碳酸盐岩的弹性变化很大，这意味着碳酸盐岩层序中的地震反射剖面可能包含不是由非碳酸盐岩插层引起的地震反射，而是主要由碳酸盐岩本身的孔隙率，孔隙类型和形状变化引起的。这项研究提供了有关碳酸盐岩的质地，岩石物理和弹性特性的重要信息，这对于评估和理解地下碳酸盐岩储层的地震反射剖面至关重要。基本上碳酸盐岩的弹性变化很大，这意味着碳酸盐岩层序中的地震反射剖面可能包含不是由非碳酸盐岩插层引起的地震反射，而是主要由碳酸盐岩本身的孔隙率，孔隙类型和形状变化引起的。这项研究提供了有关碳酸盐岩的质地，岩石物理和弹性特性的重要信息，这对于评估和理解地下碳酸盐岩储层的地震反射剖面至关重要。
