| 摘 要： | 岩石孔隙度的地下压缩校正对于石油地质储量的计算有着重要的意义。在岩石孔隙压缩理论研究的基础上，根据压缩系数的概念，通过严格的数学推导，提出了三种孔隙度地下压缩校正方法，并利用油田实际覆压下的岩石孔隙度压缩实验资料进行了分析验证。结果表明，三种方法对于全区砂岩孔隙度的地下压缩校正是可行的，并具有普遍应用价值。

| Abstract: | Underground compressed correction of porosity is of great importance for the OOIP calculation. Three methods are put forward in this paper by strict mathematical deduction based on the theoretical study of rock pore compression and the conception of compressibility coefficient. The methods are validated using test data of rock porosity compression under actual overburden pressure of the oil field. The result indicates that the methods are feasible for the underground compressed correction of sandstone porosity in the whole area and have extensive applicative value. |
