摘要
建立了基于灰色关联分析的页岩气储层分类新方法。采用灰色关联分析,定量化各因子之间的大小关系,计算得到各主、次因子的权重和页岩气储层质量综合评价因子,从而进行储层分类。实例证明,储层分类与实际生产情况吻合度非常高。该评价方法可为我国页岩气储层评价和选取提供依据。
A new classification method of shale gas reservoir based on grey association analysis is presented.Grey relational analysis method was used to define the relationship between these factors and to calculate the weights of the principle and secondary factors and the comprehensive evaluation factors of shale gas reservoir quality.Case study shows that the reservoir classification results accord well with the practical production situation.This evaluation method can be applied to shale gas reservoir evaluation and selection in China.
