摘要
岩石孔隙体积压缩系数一直是油藏工作者研究的热点问题。从岩石压缩过程与压缩系数的概念出发,通过压缩过程机理分析了实验过程中岩石压缩系数变化规律,研究了影响岩石孔隙体积压缩系数变化的因素。研究结果表明,岩石表观孔隙体积对岩石孔隙体积压缩系数影响较小,岩石的变形方式与应力状态对岩石体积压缩系数影响较大。研究成果对油藏工程研究有一定的现实意义。
The rock pore volume compressibility has always been the focus of reservoir workers. Starting from the concepts of rock compression and rock compressibility, rock compressibility changes are analyzed during the experimental process based on the compression mechanism. The facors influencing the changes of rock pore volume compressibility are studied. Results show that the apparent rock pore volume exerts less effect on the changes, while the deformation and the stress state of rock have greater impact.
