摘要
岩石压缩系数与孔隙度的关系问题是一直没有得到很好解决的理论问题,传统的经验公式示出岩石压缩系数随孔隙度的增大而减小.本文应用多孔介质力学的有关理论,推导出了岩石压缩系数与孔隙度之间的理论关系式.该关系式表明:岩石的压缩系数随孔隙度的增大而增大;岩石压缩系数受成岩矿物硬度的影响,矿物硬度越大,岩石的压缩系数越小.上述研究成果对油藏工程研究具有重要意义.
As a theoretical problem, the relationship of rock compressibility with porosity has not been established properly. The traditional empirical formula show that the compressibility of rock decreases as porosity increases. In this paper, a theoretical formula between rock compressibility and porosity has been developed by applying the theory of porous media, indicating that the rock compressibility may increase with porosity, and that the rock compressibility is controlled by the hardness of diagenetic minerals, with the compressibility decreasing when the hardness increasing. These results may be important to reservoir engineering.
