In the east part of China,shallow gas reservoir ususlly produces bright spot reflection in seismic section. Data stacking affects amplitudes, which makes it difficult to use bright spot technique in gas detection. The bright spot due to shallow gas reservoir can be determined by analysing AVO information of P-wave and converted shear wave, instead of conventional stacked section. A method is given of deriving zero-offset longitudinal and converted shear waves from conventional seismic data. A way of making relative...

In the east part of China,shallow gas reservoir ususlly produces bright spot reflection in seismic section. Data stacking affects amplitudes, which makes it difficult to use bright spot technique in gas detection. The bright spot due to shallow gas reservoir can be determined by analysing AVO information of P-wave and converted shear wave, instead of conventional stacked section. A method is given of deriving zero-offset longitudinal and converted shear waves from conventional seismic data. A way of making relative wave impedance inversion is also described. Excellent feasibility of this method is shown by an example of a shallow gas reservoir detection.

东部地区,浅层气藏一般呈亮点反射特征。由于叠加对振幅的影响,给使用亮点技术检测油气带来困难。本文提出用AVO纵波信息代替常规叠加剖面,并结合转换横波信息来检测浅层亮点气。文中给出了从常规地震资料中提取自激自收纵波、转换横波的方法及其相对波阻抗反演方法,并以一浅层气藏的检测为例,说明该方法有良好的应用效果。

球面波的平面波分解可以完成球面波波场向平面波波场的转换。这对于与振幅密切相关的波阻抗反演来说是非常重要的。为了提高平面波分解的运算速度,本文借用零阶 Bessel 函数近似形式提出了一种快速的近似算法,并进行了误差分析。由理论模型的试算结果得知,这种近似算法是可行的。将此注用于实际资料处理,对改善深层反射能量,提高同相轴的连续性和信噪比均有作用。

Wave impedance inversion using wave equation has not been used in practicalseismic data processing because of some troubles such as too much computation,poor stability and so on. Overlapped segmental inversion using 1-D wave equationcan well remove the troubles because of its quite small computation,high accuracyand good stability. The excellent effect has been seen in processing the seismic datafrom the east and west parts of the Changyuan prospect in Daqing district.

利用波动方程兵演波阻抗,由于计算工作量大、稳定性差等原因,一直没有在地震勘探资料处理中得到实际应用。本文提出的一维波动方程逐段折叠民演方法能较好地克服上还缺陷,具有计算量相对较小、精度高、稳定性好等特点,并在大庆长垣东部和西部的实际资料处理中见到了良好的效果。
