Petrel 建模中的几点认识

相建模是储层建模的关键,它为储层参数的模拟提供了储层骨架。作者对目前常用的几种相建模方法进行分析, 提出岩相建模中利用泥质含量与综合测井解释进行岩相重构的方法, 该方法适用于没有足够细致的沉积微相研究,最后, 阐述了变差函数的原理及重要性, 针对求取变差函数过程中存在问题进行分析, 提出了一套可行的方法,在实际操作过程中取得了较好效果。

Discussion on geologic modeling with Petrel

As the key in the process of reservoir modeling, facies modeling provides reservoir framework for the simulation of the reservoir parameters. Based on the analysis of several commonly used facies modeling, it was presented that using shale content and comprehensive well log interpretation to reconfigure hthofacies in lithofacies modeling, which is available for the work area without sufficient accurate sedimentary microfacies study. The principle and importance of the variogram were expounded. A set of effective methods was suggested referred to the problems occurred in the process of variogram calculation. The effectiveness of these methods has been proved in practice.
