In other words ,the use of proper static correction values brings the maximum stacked energy. Thus,the optimum static correction values can be derived from the maximum stacked energy.

If the calculation of surface-consistent static correction va-lues is considered as an optimum problem,stacked energy is the function of static correction values. In other words ,the use of proper static correction values brings the maximum stacked energy. Thus,the optimum static correction values can be derived from the maximum stacked energy. The static correction values picked up using second order difference is taken as the initial values of those picked up using the maximum energy. Then the optimum static correction values can be calculated from the initial values by performing iterative operation for several times. It is theoretically and practically shown that this method can cope with big value statics to make up the deficiency of common static correction methods.

如果把地表一致性静校正量的计算作为一个最佳问题来考虑,那么叠加能量便是静校正量的函数。也就是说,施加正确的静校正量,可使叠加能量达到极大。因而,最佳静校正量可以通过叠加能量的极大值来求得。本文采用二阶差分法拾取的静校正量作为最大叠加能量法拾取静校正量的初值,然后通过几次迭代运算,便可求出最佳静校正值。理论试算和用于实际资料处理结果表明,该法能解决大静校正量的静校正问题,克服常规静校正方法的不足。

Using stacking energy associated with velocity spectrum,adopting interpola-tion、of quadratic curve,the time corresponding to the maximum stacking energy is found,andthen dip correction,phase correction and maximum offset correction to stacking velocity aremade,and a more precise interval velocity is obtained.

本文以利用速度谱所伴生的叠加能量,采用二次曲线插值方法,寻找最大的叠加能量所对应的时间,然后利用叠加速度进行倾角校正、相位校正和最大炮检距校正,获取比较精确的层速度参数。

We advance a new surface-consistent phase correction method,which is used to correct surface seismic data by introducing the shot and receiving-point phase-cor-rection operators which are iteratively calculated on the criterion of maximum stack energy. This method is widely applicable because it considers how both static cor-rection values and varied coupling of surface layer to shot point (or receiving points)influence wavelet phases.

本文提出了一种地表一致性相位校正的方法,它是基于最大叠加能量法准则,采取迭代法求取炮点、检波点的相位校正算子,对地震记录进行校正。由于该方法同时考虑静校正量及近地表和炮点、检波点耦会的变化对子波相位的影响。所以,此法具有更广泛的适用性。
