| 摘 要： | 针对理论Dix公式求取层速度结果不可靠这一问题,应用基于指数渐进边界速度趋势模型约束Dix层速度反演技术,获得的层速度能较好地消除研究靶区水深变化、层速度纵向变化等因素引起的构造畸变影响。并且计算精度、反演速度快,得到层速度更符合地质规律。无论从理论模型的验证,及实际资料的处理,都取得了相对较好的效果。

| Abstract: | Apply the constrained Dix inversion based on the exponential asymptotically bounded velocity model to solve the velocity calibration technique. The structure distortion affection caused by depth variation, layer velocity varied in the vertical direction can be removed well by the twice velocity obtain technique, and the algorithm is accurately and fast. Not only the trial calculation of synthetic model but also the processing of actual data all produces a geological plausible, stable result. |
