摘要： 储油岩石一般为致密介质。致密介质在应力作用下,以本体变形(弹性变形)为主,孔隙度不发生变化。油气储量计算时,地面实测孔隙度不需要进行校正。传统的孔隙度校正无形中损失了一部分地质储量,同时为确定校正值大小也浪费了大量人力和物力。致密岩石弹性变形过程中的孔隙度不变性原则将给储量计算带来很大的方便。

Abstract: Oil-saturated reservoir rocks are normally tight medium. U nder the stress process, this medium is dominated by elastic deformation without porosity variation. For hydrocarbon reserve estimation, no correction of the measured porosity is required. Hence, following traditional porosity corrections, a part of OOIP is always missed intangibly. At the same time, to determine the scope of corrected values may waste great amount of manpower and material resources. It is believed that the principle of porosity invariance during process of tight rock elastic deformation will provide a good deal of convenience for OOIP or reserve estimation.
