Existing qP-wave equations suffer terrible qSV-wave residual which is disadvantage for our study. In this paper, we present a simple and useful qP-wave governing equation by using the average square approximation onto qP-wave dispersion relation derived by Thomsen(1986). Numerical results demonstrate that the proposed equation is much more accuracy and effective. The numerical wavefields generated by this equation are very clear without qSV-residual. All of these show that the proposed equation can be used to simulate qP-wave propagation in anisotropic media.
