强底水非均质块状底水油藏开发特征研究

以HB辫状河强底水块状油藏为例，探讨了同类油藏特征下产能递减规律，建立此类油藏产能递减典型曲线。结合HB油藏隔夹层分布特征与生产动态特征，将HB油藏含水上升模式分类，并从地质特征、生产时间角度分析了不同含水上升模式出现的原因，进而提出了相应的开发技术对策。研究成果对指导此类油藏后期调整以及前期布井策略都有较高的指导价值。

The research on development characteristics of heterogenous massive oil reservoir with strong bottom water

Taking HB braided river massive reservoir with strong basal ground water as an example, the paper discusses the deliverability decreasing methods of similar reservoirs and develops the curves. Combined with the barrier distribution characters and production performance of HB reservoir, the paper classifies the water cut increasing patterns of HB reservoir and proposes the corresponding development technologies by analyzing the reason that different patterns appear from geologic feature and production time. The results will provide important guidance for such reservoirs in later adjustment and well spacing strategy.
