| 摘 要： | 以济阳坳陷东营凹陷北部陡坡带民丰地区古近系沙四下亚段(E2s34)发育的近岸水下扇内的砂砾岩体为研究目标,利用该地区600km2三维叠前时间偏移地震资料和6口钻井、测井资料,选取对有效砂砾岩体敏感的测井曲线进行分析。通过测井曲线重构的拟声波三维地震反演方法对三维地震数据体进行反演处理和重构,来提高地震对有效砂砾岩体储集层的识别能力。结果表明,有效砂砾岩体地震参数分布区间在12000以上,而砂砾岩体范围为10000～12000.基于此反演数据体,实现了对研究区目的层近岸水下扇有效砂砾岩体储集层预测的目的。

| Abstract: | The selected well logs that are sensitive to the effective glutenite body are analyzed using the seismic data of 3-D prestack time migration in regional range of 600 km2 and drilling-logging data of Eogene Shasixia member (Es4) in Dongying sag of Jiyang depression basin. The 3-D seismic data volume is processed and reconstructed by means of quasi-acoustic inversion method reconstructed from well logs for the purpose of improvement of identifying ability on various effective glutenite reservoirs. The results... |
