摘要
本文根据波动方程反问题的特点,提出了岩性参数与震源同时反演的联合反演方法,解决了地震勘探中波动方程反问题的震源未知或不准确的矛盾,缩短了反演理论研究与工程实际应用间的距离。文中以一维波动方程反问题为例,详细地叙述了联合反演的计算方法,讨论了反演的精度,稳定性等数值特点,并给出了相应的数值算例。
According to the character of wave equation inverse problem, a simultaneous inverse method of the lithology parameters and seismic source function is presented. This method can be used to solve the seismie inverse problems when both the lithology parameters and seismic source function are unkown. So it is not only a theoretical method, but also a practical method. The calculative formulae of the method are derived and some numerical characters, such as accuracy, stability, etc. discussed. Then the numerical examples are given in this paper.
