| 摘 要： | 地震勘探是石油天然气及煤田地质勘探的重要方法。波动方程从本质上描述了地震波传播的基本规律。求解出波动方程中的未知系数(即物性参数),可以帮助人们发现含油气层或煤层,为钻井提供正确的井位。本文运用微分方程反问题方法计论并解决了波动方程混合问题中的两个物性参数的识别问题。

| Abstract: | Seismic prospecting is an important method for exploring petroleum, natural gas and coalo Wave equation describes intrinsically the basic principle of seismic wave transmission. To solve unknown coefficients (namely physical parameters) of wave. equation can help people find out the stratum containing oil, gas or coal, and point out the correct position for drilling the well. Using the method of inverse problem of differential equation,the paper discusses and solves the problem of determining two physical, parameters in wave eqeuation mixed problem. |
