英文摘要	With the seismic prospecting target changing from structural reservoirs to lithologic reservoirs, it requires more reliable attribute information with clear geological meanings from seismic data to identify the lithology or lithoface information of the reservoirs. The three-term AVO inversion can be used to estimate the P-wave velocity, S-wave velocity and density of the rock and fluid's properties through the amplitude variations with offset. However, the AVO inversion is essentially an ill-posed problem. The pure seismic P-wave approaches are not sensitive to the shear wave velocity and density, which causes errors in the inversion results. With the development of seismic data acquisition and data processing technology, more and more scholars begin to study the PP-PS joint inversion and apply it to field data. The joint inversion can improve the inversion accuracy and to some extent reduce the inversion instability. However, in the low signal-to-noise ratio situations, we cannot obtain good results from the joint inversion. In this paper, we propose the l(1) norm constrained sparse optimization method with the initial model generated from the particle filtering. The effectiveness of this method is verified through model tests with three different signals-to-noise ratios and its advantage in the low SNR inversion is verified by comparing it with the conventional method.
