Abstract：When formation thickness varies greatly,the inverted parameter model derived by traditional anisotropic parameter modeling based on well-seismic joint grid tomography in TTI media can be distorted.To solve this problem,an optimized anisotropic parameter modeling method in TTI media was proposed in this paper.It introduces formation thickness information into anisotropic parameter inversion through the δ-based well-seismic error interpolation,and thus makes the inversion result more accurate.Real data processing results demonstrated that the optimized method can avoid the anisotropic parameter distortion caused by the abrupt change of formation thickness effectively,and the obtained model parameters are more accurate and reasonable for they are not related to formation thickness variation.
