复杂的地质构造常使分辨地震层位变得很困难,例如在遇到盲区、断层或相的横向变化时就是这样。为了解决这个难题,我们根据地震信息的动力学特征以及现代电子计算机所能提供的最大逻辑功能提出了一种方法,即在迭代法的基础上应用判别因数分析法分辨地震层位。经过讨论和试验,我们认为对反射层的归类是令人满意的。与此同时,我们还得到了各个层位的被正确归类的反射波的百分比。
Complex geological formations often make it difficult to resolve seismic horizons, such as in the event of a blind spot, a fault, or a lateral change in phase. In order to solve this problem, we propose a method based on the dynamical characteristics of seismic information and the maximum logic function that modern electronic computers can provide, using discriminant factor analysis to discriminate seismic horizon based on iterative method. After discussion and experiment, we think the classification of reflective layer is satisfactory. At the same time, we have also obtained the percentage of properly classified reflections at each horizon.
