摘　　要：深海油田开发,目前尚未形成一套成熟的高速开发模式。就产量接替而言,主要面临着优质储量的分布规律和特点,以及根据储量分布特点制定相应的高产、稳产策略的运行规划等问题。优质储量分布规律、油藏生产潜力的研究,对于后期的井网设计,高产、稳产策略的制定等工作,起着关键性的作用。系统介绍了几类目前国内外比较常用的油藏生产潜力评价方法,并应用实例详细对比分析了这些方法各自的特点与局限性。通过研究发现,运用公式计算生产潜力作为不建立模型时的最优选择,使用固定生产井和注水井方法作为运用数学模型时的最佳选择,这两种方法具有一定准确度和可靠度。研究成果对深海油田的优势储量、油藏生产潜力评价奠定方法基础。For development of deepwater offshore oilfield, there is not a set of mature high - speed development pattern by now. In terms of future production, we are facing main problems ： distribution rule and characteristics of high quality re- serves, production schedule for high or stable production strategy based on characteristics of oil resource distribution, and so on. Research of high quality reserves distribution and potential productivity plays a key role in design of well pattern at lat- er stage of development and planning of high or stable production strategy. This paper introduces several common evaluation methods for reservoir potential productivity. The advantages and disadvantages of these methods were presented by a case a- nalysis. Results show that in the case of unavailable reservoir numerical simulation, the best choice is to use formula to cal- culate the potential productivity ; when mathematical model is available, it is good to use the method of the fixed production well and injection. The two methods both have a certain degree of accuracy and reliability. Research results lay a foundation for the evaluation method of the high quality reserves and the potential productivity in deepwater offshore reservoirs.
