摘　　要：碳酸盐岩断溶体油藏是顺北油田近年来发现的重要油藏类型,常规能量、相干属性、蚂蚁体等储集体与断裂检测技术不能满足顺北断溶体油藏研究的需求。针对断溶体内部结构采用剩余波阻抗表征串珠反射特征、不连续性属性表征杂乱反射特征以及AFE属性表征断裂与裂缝特征,形成了断溶体内部结构的刻画技术。结合顺北油田实际地震资料应用表明,该技术更能直观反应洞、孔洞、裂缝发育特征,表征断溶体内部储层的空间展布。Carbonate fault solution reservoir is an important reservoir type found in Shunbei oilfield in recent years.Conventional energy,coherent property,ant body and other reservoir and fault detection technology can not meet the needs of Shunbei fault solution reservoir research.According to the internal structure of fault solution,the residual wave impedance is used to characterize the bead reflection characteristics,the discontinuity attribute is used to characterize the chaotic reflection feature,and the AFE attribute is used to characterize the fracture and fracture characteristics.Combined with the actual seismic data of Shunbei oilfield,the application shows that the technology can directly reflect the development characteristics of caves,pores and fractures,and characterize the spatial distribution of reservoirs in fault solution bodies.
