离散裂缝或双孔隙模型已广泛用于致密岩石模拟。为了表示复杂的裂缝非均质性并简化其表征，作者在整篇论文中提出了一种新的模拟模型，以整体优化致密岩油藏完井、初次枯竭和提高采收率模型，并保留注入机制并简化复杂的裂缝表征以提高计算效率。该模型使用户能够表征多个区域的不同属性。该工具将在支持资产开发决策方面具有广泛的应用。

介绍

传统的双孔隙度、双渗透率 (DPDK) 模拟通过形状因子（基质/裂缝耦合）纳入微尺度裂缝表征，为油气混合物提供了重要的接触面积，以可靠地表示现场响应。

Discrete fracture or dual-porosity modeling has been widely adopted for tight rock simulation. To represent the complex fracture heterogeneity and simplify its characterization, the authors present in the complete paper a new simulation model to holistically optimize the tight rock reservoir completion, primary depletion, and enhanced oil recovery modeling and retain the injection mechanism and simplify the complex fracture characterization to enhance computational efficiency. The model enables users to characterize different properties in multiple regions. This tool will have broad applications in supporting asset-development decisions.

Introduction

Traditional dual-porosity, dual-permeability (DPDK) simulation incorporates microscale fracture characterization through the shape factor (matrix/fracture coupling), which offers a significant contact area for the gas/oil mixture to represent the field response reliably.
