地震反演是一个不适定问题。所有目前使用的反演算法，充其量都是近似值。因此，我们面临的问题是，许多地下模型会产生合成数据，所有这些数据都在给定的误差范围内拟合数据。经验丰富的地震解释人员的工作是根据解释人员的经验和对勘探区域的先验地质知识，从这些拟合良好的模型中选择在地质学上最合理的模型。
Seismic inversion is an ill-posed problem. All currently used inversion algorithms are, at best, approximations. As a result, we face the problem that many models of the subsurface give rise to synthetic data, all of which fit the data within a given measure of error. It is the job of the experienced seismic interpreter to choose among this set of well-fitting models those that are geologically most plausible, given the interpreter's experience and prior geologic knowledge of the area being explored.
