【摘要】 在传统油藏数值模型基础上建立具有井下监测和控制功能模块的储层数值模型,提出一种智能井Proactive和Reactive反馈控制算法。基于此模型和控制算法并以水平井生产为例,开展Proactive控制、Reactive控制以及两者结合的混合式控制的生产策略研究。结果表明:相对传统井生产,基于Reactive和Proactive的反馈控制策略可以减少产水量、增加产油量,提高净产值;Proactive控制在生产前期优势较大,而Reactive控制在生产后期优势较为明显,两者结合的混合式生产控制策略优于单独的Proactive和Reactive生产策略。更多还原

【Abstract】 A numerical model of reservoir production with the functionalities of real-time monitoring and control was established based on traditional reservoir numerical model and a set of proactive and reactive feedback control algorithms were proposed. Three intelligent well production strategies( i. e.,reactive control,proactive control and the combined control) were investigated in a scenario of water-flooding driven horizontal production wells. The results show that compared with the conventional well production,the feedback controled production strategies can increase oil production,decrease water production,and thus improve the net present value. The proactive control displays advantages in the early production stage while the reactive control outperforms in the late stage,and the production strategy with combined reactive and proactive controls has the most advantage in economic return aspect.更多还原
