The Effects of Saturation and Porosity on Petrophysical Properties and AVO Characteristics

摘要

Based on petrophysics experimental study, this paper expounds the feasibility of reservoir prediction and hydrocarbon detection by seeking the relationship between petrophysical characteristics and seismic properties of certain area in Liaodong Bay, Bohai Sea. Through simulating temperature and pressure conditions of subsurface reservoir in the core experiment, the paper also studies the rule of P-wave/S-wave velocity of core changing with fluid saturation and the effects of different petrophysical properties on AVO characteristics.
