| 摘 要： | 针对油层与水层的地震响应特征较为接近,常规的流体检测手段预测油层效果不理想的问题,通过测井、地质、地球物理的综合研究以及理论模型和实际资料的统计分析,由振幅和甜点属性的相对变化量对富含油储层的地震响应特征进行分析,并定量地总结了规律。研究结果表明:当油层厚度较小时,振幅和甜点的相对变化量也较小,且与油层厚度没有明显关系;随着油层厚度的增大,振幅相对变化量线性增大,甜点相对变化量指数增大,增大的速度更快。甜点属性能够放大油层和水层之间的差异。 |
| 关 键 词： | 富含油储层 地震响应特征 振幅 甜点属性 相对变化量 |

| Abstract: | The seismic response characteristics of oil layer and water layer are close,and conventional fluid prediction methods cannot get satisfactory result for oil layer prediction.Through integrated study of well logging,geology and geophysics,and statistical analysis of theoretical model and field data,the seismic response characteristic of oil-rich reservoir was analyzed from the point of the relative variations of amplitude and sweetness,and its regularity was summarized quantitatively.The results show that when the thickness of oil layer is small,the relative variations of amplitude and sweetness are small too,and they have no obvious relationship with the thickness of oil layer.With the thickness of oil layer increasing,the relative variation of amplitude increases linearly,and that of sweetness increases exponentially with higher rate.Sweetness can amplify the difference between oil layer and water layer. |
| Keywords: | oil-rich reservoir seismic response characteristic amplitude sweetness relative variation |
