  • The technology of reservoir fluid identification based on seismic data plays an important role in the recent hydrocarbon exploration.Utilizing the rock modulus parameter and quality factor as reservoir fluid indication factor,we research two methods to raise the reliability of estimated fluid indication factor,which are the elastic modulus parameter direct estimation method based on elastic impedance inversion and quality factor estimation method based on the wavelet-domain QVO technology,respectively.Besides taking full advantage of elastic impedance inversion to have high signal-noise-ratio and practicability,the rock modulus direct estimation method can diminish negative effect of accumulative error.Based on the assumption of zero phase wavelet,the quality factor estimation avoids the stack effect using the return-zero process of quality factors estimated from prestack wavelet-domain.The model test shows the viability of the two methods,and real data example illustrates further that the utilization of both information of rock modulus and quality factor can improve the quality of reservoir fluid identification.
