The moderate deep and deeplayers of the Ledong area in the Yinggehai Basin is regarded as the main districts in recent exploration. The reservoirs in L10 zone are generally characterized by low-porosity and low-permeability, suggesting that the high-quality reservoir is the main focus restricting the further research and exploration. Through the analysis of regional petrophysical features, we established AVO template of velocity of overburden mudstones and porosity, to improve the effectiveness of AVO technology in predicting reservoir physical properties. Aiming at the large errors of porosity predicting in thin reservoirs, a new porosity prediction method based on impedance correction formula was proposed, which improved the prediction accuracy of thin layers. Numerical simulation and drilling data verified the validity and reliability of this new method and provided new directions for subsequent high-quality reservoir exploration in the Yinggehai Basin.
