摘要
从油层物理对孔隙度及岩石几种不同压缩系数的基本概念入手,采用2种方法推导出岩石孔隙体积压缩系数、岩石总体积压缩系数及岩石骨架体积压缩系数的关系式。此表达式的导出有助于储层孔隙度、渗透率变化规律的研究及油藏工程基础研究。
Based on the concept of reservoir porosity and several different compression coefficients of rock in reservoir physics,two methods have been employed to derive the relation equations of rock pore volume compressibility,bulk compressibility and rock matrix compressibility. The equations are helpful to the study of reservoir porosity and permeability and the basic research of reservoir engineering.
