在井下微震监测中,各向异性模型用来获取事件位置和给出对介质实际描是十分有用的。在各向异性介质中,因为横波的分裂和奇异点的出现,使得波场的结构变得复杂。我们的研究展示了对强烈各向异性VTI介质利用速度模型校准和双偶极震源进行常规处理和运动学反演的结果。因小走时的拟合差,常用的质量评价标准,不是总正确的,人工加入各向同性介质层以降低拟合差,也可能产生非物理模型,负泊松比,事件位置的位移 In downhole microseismic monitoring, the anisotropy model is very useful for obtaining the location of the event and for giving a realistic representation of the medium. In anisotropic media, the structure of the wavefield is complicated by the splitting of shear waves and the appearance of singular points. Our study shows the results of routine processing and kinematic inversion of velocity model calibration and dual dipole sources for strongly anisotropic VTI media. Due to poor fitting when walking small, the commonly used quality evaluation criteria are not always correct. Artificial isotropic isotropic medium is added to reduce the fitting difference, and non-physical model may also be generated. The negative Poisson’s ratio, the displacement of the event location
