| 摘 要： | 利用白音查干地区的测井、录井及地震资料。通过定性、定量两种手段进行瞬时频率与岩性的相关性分析,认为瞬时频率能够较好的区分砂泥岩。当砂岩百分比小于0.12时,瞬时频率属性为低频;当砂岩百分比为0.16～0.33时,瞬时频率为高频。通过瞬时频率切片与沉积相平面展布图对比分析发现,不同相类型的砂体在瞬时频率切片中具有明显不同的特征,辫状河三角洲砂体表现为沿物源方向延伸的枝状或朵状中高频区,滩砂表现为不规则滩状的高频区,坝砂在盆地边缘呈高频带状分布。此外,瞬时频率还可以进行物源分析、三角洲朵叶体识别和扇体叠置识别,是进行沉积体系、砂体展布和储层预测等方面研究的重要手段。 |

| Abstract: | The effect of instantaneous frequency properties in sedimentary facies and the correlation of instantaneous frequency properties and lithologic in Baiyinchagan region are studied by using well logging and seismic data with qualitative analysis and quantitative analysis.It is showed that sand and shale can be distinguished through instantaneous frequency attribute.If the sandstone percentage is less than 0.12,the instantaneous frequency attribute appears as low frequency,else if the sandstone percentage ranges from 0.16 to 0.33,the instantaneous frequency occurs as high-frequency.In addition,different types of sand body show different characteristics in the plane of the instantaneous frequency.Braided river delta sand body is manifested as dendritic or flower-shaped high frequency area extending along the source direction.Beach exhibits in high frequency region of the irregular-shaped beach.Dam showed a high frequency ribbon in the edge of the basin.Instantaneous frequency attribute can also analyze the source,identify the delta lobes body and recognize the overlaying fan bodies.Therefore,instantaneous frequency is a very effective method for sedimentary system research,the sand body distribution and reservoir prediction. |
