【摘要】 利用三维地质建模对砾岩储层非均质性进行定量研究和高密度定量表征,阐明油田主要挖潜方向及潜力区。储层构造建模建立了一种利用地震解释、钻井对比得出的断点数据与分层数据相互校正的构造模型;沉积微相建模定量表述了储集砂砾体大小、几何形态及其三维空间分布;相控储层参数建模实现了储集相带分布概率、原始储层数据及三维地质解释经验约束的储层参数模型。通过建模较好地解决了各种数据分辨率不同给储层数据信息结合制造的矛盾,优选出符合油田实际生产状态的非均质砾岩储层地质模型,形象、直观地显示出砾岩油藏断裂扩边潜力区和有利沉积相带控制油气储层规模及范围。更多还原

【Abstract】 The heterogeneity of conglomerate reservoir is studied by 3D geologic modeling.The main potential tapping and potential zone are illustrated.The 3D geologic modeling includes reservoir structure modeling,sedimentary microfacies modeling and reservoir parameter modeling.The structure modeling achieves the intercalibration process of fault-point data and individual layer data derived from seismic interpretation and drilling.Sedimentary microfacies modeling displays the reservoir volume,geometric shape and 3D distribution.Reservoir parameter modeling carries out the reservoir parameter model constrained by facies belt distribution range,original reservoir data and 3D geologic interpretation.The result shows that the modeling overcomes the disadvantage caused by various data with different resolution,optimizes the geologic modeling for heterogeneity conglomerate reservoir suitable for practical production,and indicates the potential zone and reservoir range controlled by favorable sedimentary facies belt.更多还原
