摘　　要：为将基于缝间(段内)射孔暂堵球与缝内暂堵剂的“缝间-缝内”暂堵压裂技术转化为实验教学内容,该文设计了井筒-射孔-裂缝全耦合暂堵压裂物理模拟实验装置。装置能够设置泵注压力、排量、射孔参数、裂缝粗糙程度、裂缝宽度等实验条件,开展非常规储层暂堵压裂物理模拟实验,并通过进出口流量监测、多点测压、可视化图像处理等方式对实验结果进行精细化表征,对段内暂堵与缝内暂堵两种压裂辅助工艺进行评价优化。该实验装置占地面积小、操作简便安全、功能丰富,是储层改造技术创新实践平台的重要组成部分。[Objective]The“inter-fracture-intra-fracture”plugging diversion fracturing technique is an effective approach for regulating fracture propagation and increasing fracture complexity in unconventional reservoirs.To support research and teaching in this area,we have developed a comprehensive physical simulation experimental system that integrates wellbore,perforation,and fracture processes.The primary goal of this system is to enable detailed physical simulations under a range of conditions,thereby advancing both the theoretical understanding and practical application of plugging diversion fracturing.This technology aims to effectively control fracture propagation and enhance fracture complexity,which is crucial for improving reservoir stimulation efficiency.To address the educational and research demands related to temporary plugging fracturing,we have created a fully integrated physical simulation system that couples wellbore,perforation,and fracture models to replicate the entire temporary plugging fracturing process across various scenarios.[Methods]The experimental system is designed to accommodate two primary fracturing processes:segmental plugging and intra-fracture plugging.The system facilitates experiments under varying conditions,including different pumping pressures,flow rates,perforation parameters,fracture roughness,and fracture widths.It employs flow rate monitoring at both the inlet and outlet,multipoint pressure measurements,and image processing techniques to provide a comprehensive characterization of the experimental outcomes.The system design emphasizes compactness,user-friendly operation,and safety,making it well-suited for use in both academic research and industrial applications.[Results]The experimental setup has proven capable of simulating the entire process of plugging diversion fracturing,from surface operations to subsurface responses.Through precise measurements and visual observations,the system captures the movement and blocking behavior of plugging materials within the wellbore,p
