摘　　要：针对低渗透油藏采收率相对较低、剩余油分布复杂的问题,采用低渗油藏开发流体势理论模型研究关键参数评价及实例区应用的方法,建立了低渗油藏不同开发阶段的流体势理论模型。基于模型建立庄36区长8油藏流体势定量分布图,对长8油藏剩余油分布进行研究。结果表明:开发流体势包括位能、压能、动能及界面能,提出了3类低势能控制的剩余油分布区,即低位能低势潜力区、低压能低势潜力区及低界面能低势潜力区。针对不同类型低势能潜力区提出不同的挖潜措施,应用上述方案在研究区取得了较好的现场应用效果,可为低渗油藏剩余油的分布研究提供参考。Aimed at the low recovery rate and complex distribution of remaining oil in low permeability reservoir, development flu-id potential theoretical model of different development stage in low permeability reservoir was established, based on which the fluid potential distribution model of Chang 8 reservoir in Zhuang36 block has been obtained and its remaining oil distribution has been studied. The results show that development fluid potential in low permeability reservoir includes gravitational potential energy, pressure energy,kinetic energy and interfacial energy. Three kinds of remaining oil patterns controlled by low potential are proposed： low gravitationaU low pressure and low interfacial energy potential area Different exploitation measures have been put forward according to different types of low fluid potential energy area. The above method has been applied in studied area with good effect For other low permeability reservoirs, the use of this method has great significance in the study of remaining oil distribution
