Revolutionizing Tight Reservoir Production: A Novel Dual-Medium Unsteady Seepage Model for Optimizing Volumetrically Fractured Horizontal Wells

This study presents an avant-garde approach for predicting and optimizing production in tight reservoirs, employing a dual-medium unsteady seepage model speci cally fashioned for volumetrically fractured horizontal wells.Traditional models o en fail to fully capture the complex dynamics associated with these unconventional reservoirs.In a signi cant departure from these models, our approach incorporates an initiation pressure gradient and a discrete fracture seepage network, providing a more realistic representation of the seepage process.The model also integrates an enhanced uid-solid interaction, which allows for a more comprehensive understanding of the uid-structure interactions in the reservoir.This is achieved through the incorporation of improved permeability and stress coupling, leading to more precise predictions of reservoir behavior.The numerical solutions derived from the model are obtained through the sophisticated nite element method, ensuring high accuracy and computational e ciency.To ensure the model's reliability and accuracy, the outcomes were tested against a real-world case, with results demonstrating strong alignment.A key revelation from the study is the signi cant di erence between uncoupled and fully coupled volumetrically fractured horizontal wells, challenging conventional wisdom in the eld.Additionally, the study delves into the e ects of stress, fracture length, and fracture number on reservoir production, contributing valuable insights for the design and optimization of tight reservoirs.The ndings from this study have the potential to revolutionize the eld of tight reservoir prediction and management, o ering signi cant advancements in petroleum engineering.The proposed approach brings forth a more nuanced understanding of tight reservoir systems and opens up new avenues for optimizing reservoir management and production.
