| 摘 要： | 工区目的层的岩性主要为低速煤层、高速灰岩和等速砂泥岩,地震资料中波阻抗和强振幅主要反映了低速煤层和高速灰岩,由于砂泥岩为等速,所以利用速度反演和波阻抗不能有效解决该类型砂岩储层的识别问题.通过孔隙度反演和有争议的自然伽马反演探讨了砂岩厚度和有利储层预测的可信度.3种反演的结果对比表明,在砂泥岩等速和存在煤层、灰岩等异常... |

| Abstract: | The principal rocks in the study area are mainly composed of low-velocity coal layer,high-velocity carbonates and iso-velocity sandstone and shale layers.Seismic acoustic impedance and high amplitude are caused by low-velocity coal and high-velocity carbonate layers.Since sandstone shares the same feature as shale in velocity in this area,it is not effective to utilize acoustic impedance and velocity inversion techniques to identify the sandstone reservoir.This study covers the reliability of predicting san... |
