摘　　要：针对埕岛油田东南部馆上段河道砂体储层预测较为困难的问题,在分析储层基本特征和地球物理特征的基础上,采用均方根振幅属性、分频属性、地层切片、地震波形指示反演以及三维可视化显示等技术,对馆上段河道砂体储层进行了定性和定量预测。研究结果表明:地震属性对储层的平面展布刻画较为清晰,地震波形指示反演技术使储层的纵横向识别精度同步提高,三维可视化技术可快速直观地对地震属性和砂体进行合理地质解释。综合预测结果与已钻井具有很高的符合率,克服了单一属性预测所带来的多解性和不确定性,可为油田精细勘探开发提供有效技术支撑。Aiming at the issue that the reservoir prediction of channel sand body in upper member of Guantao Formation in the southeast of Chengdao oilfield is relatively difficult, on the basis of analyzing the basic characteristics and geophysical characteristics of reservoir, the techniques like RMS amplitude attribute, separate frequency seismic attribute, strata slice, seismic waveform indication inversion and 3D visualization display were used to carry out qualitative and quantitative prediction on the channel sand body reservoir of upper member of Guantao Formation. The study results show that the depiction on horizontal distribution of reservoir by seismic attributes is relatively in focus, the seismic waveform indication inversion technique allows the vertical and horizontal identification accuracy of reservoir to be synchronously improved, and the 3D visualization technique can quickly and intuitively carry out reasonable geologic interpretation on seismic attributes and sand bodies. The integrated prediction results have a high coincidence rate with the drilling results, which overcomes the ambiguity and uncertainty brought by single attribute prediction, and can provide effective technical support for the fine exploration and development of the oilfield.
