摘要
以塔里木盆地塔中Ⅲ区奥陶系一间房组碳酸盐岩缝洞储层为例,对碳酸盐岩缝洞储层地质建模方法进行研究。结果表明:碳酸盐岩缝洞储层在地震剖面上呈串珠状或片状强反射特征,提取地震数据体的均方根振幅属性体作为软数据,将井上的测井解释成果作为硬数据,选用序贯指示模拟和多因素约束法建立储层相模型,相互对比并结合实际钻井情况分析后认为Variogram约束面法建立的叠加模型效果最好。
Fractured cave reservoir in carbonate rock can be seen as beaded or flake strong reflection characteristics in seismic section.Extracting RMS amplitude from seismic data as soft data,well logging interpretation as hard data,selecting the sequential indicator simulation and multi-factors constrained method,a reservoir facies model was established.According to the comparative research between each other and analysis in combination with the actual drilling situation,we believe that superposition model made by variogram constraint surface method is the best.
