The seismic events, recorded from seismic survey, are the reflection of either the existance of the wave impedance interface, or in most cases, the existance of the density interface. In areas where the seismic survey and the gravity investigaton have been made, the density differences among the upper and the lower impedance interfaces could be successfully determined by the shape of such interfaces and the change of the gravity anomaly, and hence the density of the interested interval...

The seismic events, recorded from seismic survey, are the reflection of either the existance of the wave impedance interface, or in most cases, the existance of the density interface. In areas where the seismic survey and the gravity investigaton have been made, the density differences among the upper and the lower impedance interfaces could be successfully determined by the shape of such interfaces and the change of the gravity anomaly, and hence the density of the interested interval could be determined. In this paper the interval-density determination by gravity and seismic data was described and its preliminary results were presented.

地震剖面上的反射波组,既反映了波阻抗界面的存在,也常常反映了密度界面的存在。在既有地震资料又有重力调查资料的地区,能够利用波阻抗界面的分布形态和重力异常的变化,成功地确定波阻抗界面的上、下岩层间的密度差,从而也就能求得所研究剖面段的层密度。本文讨论了利用重力和地震资料确定层密度的方法和试验所取得的初步结果。

Anisotropic medium research is an important field in exploration seismology.The azimuthal interface is a special phenomenon in anisotropic medium. First, the meaning of azimuthal interface is explained briefly. Then, extensive dilatancy anisotropic (EDA) medium is taken as an example to discuss three types of azimuthal interface, whose wave equations for numerical modeling are given respectively.

Anisotropic medium research is an important field in exploration seismology.The azimuthal interface is a special phenomenon in anisotropic medium. First, the meaning of azimuthal interface is explained briefly. Then, extensive dilatancy anisotropic (EDA) medium is taken as an example to discuss three types of azimuthal interface, whose wave equations for numerical modeling are given respectively. Finally, wave field numerical modeling is done by using finite element method. The modeling result demonstrates that the azimuthal interface is also wave impedance interface. This method may be applied to TIM, PTL and other hexagonal anisotropic media.

研究各向异性介质是勘探地震学中的一个重要内容。方位界面是各向异性介质中的一种特殊现象。本文首先解释了方位界面的含义;然后以裂隙各向异性介质(EDA)为例,讨论了方位界面存在的三种情况,并给出每种情况下的数位模拟波动方程;最后,用有限元方法作了波场数值模拟。模拟结果表明方位界面也是波阻抗界面。本文讨论问题的方法可以扩展到TIM、PTL等其它六方各向异性介质。

The amplitude anomalies on reflection profile generated from controllably explosive source in southern Guizhou which represents a marine sedimentary environment indicate thebright, faded and darken spots. The inter'Pretation of these spots may imply that there is presence ofoil and gas reservoirs marked by the bright spots. The faded Spots might reflect a wave impedance interface between gas reservoirs and non-gas-bearing beds, whereas the darken spotS reveal the interlayer reflection caused by a shift...

The inter'Pretation of these spots may imply that there is presence ofoil and gas reservoirs marked by the bright spots. The faded Spots might reflect a wave impedance interface between gas reservoirs and non-gas-bearing beds, whereas the darken spotS reveal the interlayer reflection caused by a shift in lithology.

黔南海相沉积地区,在可控震源与炸药震源的地震普查勘探中,地震反射剖面上,出现的振幅异常,有“亮点”、“平点”与”暗点”显示。研究认为:“亮点”可能为油气层的显示;“平点”可能是含气储层与不含气层之间形成的波阻抗界面;“暗点”可能为岩性变化的层间反射。
