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。
Taking the carbonate rock fracture zone reservoir of Ordovician-Fangfang Formation in Tazhong Ⅲ area of Tarim Basin as an example, the geological modeling methods of carbonate fracture zone and reservoir were studied. The results show that the fractured carbonate reservoir has a beaded or sheet-like reflection feature on the seismic profile. The root mean square amplitude of the seismic data body is extracted as soft data and the well logging interpretation results are used as hard data , The reservoir facies model was established by using sequential indicator simulation and multi-factor constraint method. Compared with each other and combining with the actual drilling situation analysis, the overlay model established by the Variogram constraint surface method was the best.
