摘要
针对砂泥岩薄互层反演中各种参数的选择对反演结果精度的影响问题,开展了多项参数实验.针对地震反演中变差函数值的求取和选择,论证不同变差函数类型、不同方向变程对反演精度的影响,得出适合研究区的变差函数参数.实际资料应用表明,反演结果与井上的信息吻合,井间地震信息丰富,预测结果可信.
In order to deal with the effect of inversion parameters on the prediction accuracy of thin interbedded sand shale,we have conducted a number of trials,according to variogram calculation and choice in inversion,expounded and proved the effect of the different variogram and range in different directions,arrived at the right variogram parameters for the studied area.The actual application shows that the inversion result consists with what is shown on the wells,with abundant seismic information between wells and reliable prediction results.
