【摘要】 叙利亚A油田是典型的裂缝性灰岩油藏,其目的层J组具有低阻、高孔、低渗特征,油气主要富集在裂缝之中。利用岩心、常规测井和FMI(地层微电阻率扫描成像)测井资料对储层裂缝进行定性识别,通过计算裂缝孔隙度、裂缝张开度和裂缝权衡评价分数,将J组裂缝层分为Ⅰ、Ⅱ、Ⅲ共3类进行有效性评价,分析结果与试油、生产情况相符,取得了良好的应用效果。更多还原

【Abstract】 A Oilfield was a typical fractured limestone reservoir in Syria,J Formation in the target zone had the characteristics of low resistivity,high pore and low permeability and oil was mainly enriched in fractures.Conventional logging and imaging logging data were used for a qualitative identification of reservoir fractures.Through calculating fracture porosity,its aperture and weight evaluation factor,the fractured reservoir of J Formation is evaluated and classified intoⅠ,Ⅱand Ⅲ classes,the result is consistent with that of formation test and situation of production,good application effect is obtained.更多还原
