| 摘 要： | 根据裂缝性油藏水平井渗流特征,将渗流区域等效为近井区域和远井区域.远井区域视为连续均匀介质.在近井区域,基于势叠加、镜像反映原理和微元线汇思想,建立考虑天然裂缝和水平井生产段共同渗流的耦合模型.组合两个流动区域得到裂缝性油藏水平井产能评价模型,并进行求解.实例计算结果表明,由于考虑了裂缝之间的干扰,用建立的模型计算的水...

| Abstract: | Based on flow characteristics of horizontal wells in naturally fractured reservoirs,vadose area is divided into two zones: near wellbore zone and far wellbore zone.The far wellbore zone is featured by its continuous homogeneity.In near wellbore zone,a coupling model is established considering fluid flow in fracture and horizaontal well simultaneously.Principles of potential superposition and mirror reflection as well as the concept of infinitesimal line congruence are used in the model.Combining flow charac... |
