地震反演结果的评价方法

在地震反演中，由于观测数据的有限性和误差，使得地震反演结果的非唯一性广泛存在，求得的模型是实际模型在一定范围内的平均值。地震反演结果的评价是建立在现有观测数据精度和尺度基础上的。在进行地震反演时，反演结果的分辨率主要取决于地震问题的本质。对不同精度和尺度的观测数据，可以通过应用各种技术和方法来消除误差和干扰，使之尽可能地逼近所对应的原始观测数据已确定精度和尺度最高分辨率的反演结果，尽可能达到地震本身应有的分辨率。反演结果必须是在方差和分辨率之间折衷的综合评价，不能盲目地提高分辨率，使反演结果的方差过大而失败。

The evaluation method of seismic inversion

In seismic inversion, the result is non-unique because of the finiteness and error of measured data The obtained model is the average value of the real model. The evaluation of seismic inversion is based on the precision and scale of the available measured data; it must be the comprehensive evaluation between the variance and resolution. Resolution from inversion result is lie on the essence of the seismic. For observation data on different precision and measure, remove the error and interfere by the various technology, possibly approach original observation data, ensure inversion result from precision and measure high resolution, achieved the resolution per se possibly. Otherwise, raising the resolution blindly can result in the very large variance and failure.
