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.
