摘要:
顺北断溶体油藏储层沿深大断裂及分支断裂发育,具有树型剖面特征,为了分析分支断溶储层动态连通对压力响应的影响,建立了双分支断溶体储层水平合采井压力响应模型。经过裂缝渗流-溶洞储集流-井筒管流的耦合、空间变换和数值反演方法,得到了双分支断溶体合采储层压力曲线,根据压力响应双对数曲线划分了储层流动阶段。各分支储层物性、空间位置以及重力效应的敏感性分析结果表明,压力导数V型曲线可直接诊断断溶体合采储层分支数量。V型曲线的出现时间受溶洞储集性、距离的影响,V型形状受裂缝物性、深度的影响,边界控制流段压力导数曲线斜率受重力效应大小的影响。研究结果为通过压力响应获取断溶体分支储层物性和空间位置提供了理论依据。
Abstract:
Fault-karst reservoirs in SHB Oilfield have tree-shape characteristics that reservoir develops along deep-large multibranched faults. Currenting fault-karst reservoirs are not considering the connectivity of multibranched fault-karst reservoir. In order to fill this gap, a novel pressure transient analysis model for horizontal commingled production well in double branched fault-karst reservoir was established. Through the flow coupling, spatial transformation and numerical inversion, the pressure solution of the double-branched fault-karst reservoir was obtained. The flow regimes were divided by the pressure response curve. The sensitivity analysis results of thephysical properties, locations and gravity effects of each branch fault-karst reservoir show that: first, the branches number could be directly obtained from the number of V-shaped on pressure derivative curve. Second, the time of V-shape appears was affected by storability and distance of cave region. Third, the shape of V-shape was affected by physical properties and depth of fracture region. Fourth, the slope of pressure derivative curve in the boundary control flow regime can capture gravity effect. The research results provide a method to diagnosing physical properties and position of multibranched fault-karst reservoir by analyzing transient pressure response.
