摘    要:
三维地震资料的高保真融合处理,可使资料的信噪比得到提高,方位角信息得到增加,构造成像更加清晰准确,从而提高潜山构造碳酸盐岩缝洞体识别精度。对冀东油田南堡3号潜山构造先后两次采集的三维地震资料进行了高保真融合处理。结果表明,在三维融合资料预测得到的裂缝发育相对密度平面上,反映出的裂缝分布规律明显,裂缝方向预测精确,且与测井资料吻合较好。这一方法特别适合叠前方位各向异性的碳酸盐岩裂缝检测。

Abstract:
The high-fidelity merging processing is an efficient method suitable for detecting fractures in carbonate rock with the pre-stack azimuth anisotropy. It is successfully used to process the 3-D seismic data from Nanpu-3 buried-hill area in Jidong Field. The result shows that in plane maps of fracture density predicted from the multi-collecting 3-D seismic data through merging processing, the predicting fractures in carbonate rock are well regular in distribution and quite accurate in direction, which is also highly consistent with the logging data.
