摘　　要：为了进一步发挥地震资料在表征井间砂体变化方面的优势，在喇嘛甸油田萨三组开展了密井网条件下地震沉积学技术研究。结果表明：经过地震相位旋转处理后，波阻抗差异明显的储层砂体与地震反射特征对应良好；利用相移地震资料可以直接预测5m以上河道砂体的分布情况；等时地层切片能够较好地反映纵向上的储层沉积特征，进而提高识别河道砂体边界的能力。该技术是密井网条件下井问储层预测的有效方法。In order to make further use of the advantages of the seismic data in the characterization of the sandbody changes among the wells, the technical studies on the seismic sedimentology are conducted for Layer S m in Lama- dian Oilfield under the condition of dense well pattern. The results show that after processing of the seismic phase shift, the correspondences between the reservoir sandbodies with the obvious contrast of the wave impedance and seismic reflection characteristics are much better; with the help of the phase-shift seismic data, the distribution of the channel sandbodies with thickness more than 5m can be directly predicted; the isochronie stratal slicings can very well reveal the vertical sedimentary characteristics of the reservoirs, thus the ability to identify the sandbody edges can be greatly improved, so the sedimentology has become the effective approach for the reservoir prediction in the density well pattern.
