油田经典地质统计学反演方法是一种随机声波阻抗反演方法。通过执行地质统计学反演算法,结果生成多个等概率波阻抗实现。其结果受到地震数据,测井数据,地质统计学参数的约束。反演结果的应用是多方面的,其中一种应用方法是利用地质统计学反演结果,进行岩相模型的实现。在此基础上,再进行岩相模型统计分析,从中选出较好的实现进一步应用于油田开发或者约束储层物性参数模型的建立。
The classical inversion of oilfield geostatistics is a stochastic acoustic impedance inversion method. By performing a geostatistical inversion algorithm, the result is multiple equipotential wave impedance generation. The results are subject to seismic data, log data, and geostatistical parameters. The application of inversion results is multifaceted. One of the applications is to use the results of geostatistics inversion to carry out the lithofacies model. On this basis, the statistical analysis of the lithofacies model is carried out, and a better implementation is selected for further application in the development of the oilfield or the establishment of a constitutive model for constrained reservoir properties.
