含裂隙储层模型数值模拟对比分析

Comparative Analysis of Numerical Simulation of Fractured Reservoir Models

本文从等效地质模型理论出发,总结、分析常用的描述含裂隙储层的Hudson模型和Cheng模型的理论基础,通过数值模拟分别获得了两种模型的独立弹性常数与模型裂隙密度之间的关系,分析含裂隙储层模型的优缺点和适用范围,为含裂隙储层的AVO响应特征曲线研究提供模型优选参照。

Starting from the theory of equivalent geological models,this article summarizes and analyzes the theoretical foundations of commonly used Hudson-Model and Cheng-Model for describing fractured reservoirs.Through numerical simulation,the relationship between the independent elastic constants of the two models and the fracture density of the models is obtained.The advantages,disadvantages,and applicability of the fractured reservoir model are analyzed,providing a reference for model selection in the study of AVO response characteristic curves of fractured reservoirs.
