| 摘 要： | 四川盆地蜀南地区下二叠统茅口组缝洞型储层具有强烈的非均质性特征,而且埋藏相对较深,信噪比和分辨率较低,地震预测的难度大。这里通过模型正演,分析不同道距二维地震资料对茅口组单缝洞体储层的分辨能力,并且在资料处理中,研究了高密度地震资料对抑制空间假频,以及提高横向分辨率的影响,最后通过实际资料对比和速度反演,进一步分析证实了高密度采集地震资料,能够有效提高缝洞型储层的预测精度。

| Abstract: | For the strong heterogeneity characteristics and buried comparatively deeper,as well as signal-tonoise ratio and resolution is relatively low,Seismic Reservoir Prediction of the lower Permian Maokouan strata fractured-cave reservoirs in southern Sichuan basin is very difficult.Based on forward modeling of two-dimensional geologic structure,this paper analyzes the resolution of two-dimensional seismic data to the single fractured-cave reservoirs by different offsets,and It also studies how the high density s... |
