| 摘 要： | 伊犁盆地侏罗系内部煤系地层发育,地震反射能量强,连续性好,可全区对比追踪.由于煤层速度低而围岩速度高,反射系数大,与上覆白垩系底界面及地面形成多次反射波.且多次反射波类型复杂,给多次反射波压制处理带来困难,严重影响了地震资料的可靠性.因此,在资料采集和处理时,需要在工区内多次反射波特点分析的基础上,提供合适的采集和处理... |

| Abstract: | In Jurassic of Yili Basin,coal measure strata were well developed and had the characteristics of strong seismic reflected energy and better continuity,the comparative tracking for sand bodies could be carried out in the whole area.However,due to the low-velocity of the coal measure strata and high-velocity of the surrounding rocks,the reflection coefficient was higher and complex reflected wave was created between the bottom of overlying Cretaceous and surface.Because of the complexity of multi-reflected wa... |
