多参数地震属性在大邑地区超致密储层预测中的应用

大邑地区主要目的层须家河组主要发育暗色含煤、河湖沼泽相及陆相碎屑岩。多期次构造运动造成该地区断裂十分发育，地质条件特另4复杂，储层特征为低孔、低渗的超致密储层。单一研究方法不能准确的预测本区有利储集带。研究根据测井和地震响应特征分析，建立大邑构造有效储渗体的地震响应模武“低频弱反射阴影带”．并结合构造、沉积分析、砂体分布，采用振幅异常、吸收系数异常、Proni滤波因子等多属性参数对储层的含气性进行油气综合检测．取得了很好的效果。

Application of Multi-parameter Seismic Attributes in Forecasting Super Tight Reservoir in Dayi Area

The main target zone of Dayi Area as Xujiahe Formation in which the dark coal-bearing,fluvial-lacus-trinepaludal facies and continental clastic rock are grown.Based on analysis of the response characters of log and seismic data,the seismic response mode of "low frequency weak reflector shadow zone" of effective reservoir was established in Dayi structure.To integrate sedimentation analysis,sand body distribution analysis and use of multi-parameter seismic attributes to detect gas-bearing properties of reser...
