| 摘 要： | 实测的岩石压缩系数数值普遍偏高，甚至高于地层原油的压缩系数，该现象是由于岩心的表皮效应所致。由于岩心表面不够光滑，岩心与封套之间存在一定的微间隙，当岩心受到压缩时，微间隙也随之受到压缩，从而增大了岩石的压缩系数。

| Abstract: | The measured rock compressibility is generally higher, or even higher than that of formation oil. This is due to the skin effect of cores. There is certain minor interspace between cores and packets because the surface of cores is not smooth enough. When cores are compressed, the minor interspace will be also compressed. So, the compressibility of rocks will be higher. |
