【摘要】 为研究准噶尔盆地南缘地区地层中地震波的衰减机制及该区地震波传播、衰减规律 ,采用实验室测定的方法 ,对该区岩石的吸收特性进行了测试和研究。根据实验观测结果 ,该区地震波速度与介质品质因子具有较好的对数线性关系 ;该区品质因子受岩石所处环境条件及岩石性质的影响比较大 ,其中岩石饱和度和介质所受的应力大小对品质因子的影响尤为突出更多还原

【Abstract】 In order to study the attenuation mechanism of wave velocity in the strata in Zungaria Basin and its propagation and attenuation regualation, the characteristics that the rock in the research area absorbs seismic wave were measured in a lab. According the lab result, in this area, the seismic wave velocity has a logarithmic linear correlation with the medium quality factor; the quality factor is effected most by the lithology of the rock and the conditions where it lies in, especially the water saturation level of the rock and the stress upon the rock.更多还原
