摘　　要：苏丹GU油田的3D地震资料信噪比和分辨率较低,该区处于断陷盆地、构造复杂,精确构造解释是保证有效开发的前提。在对该区地震资料进行重新精细构造解释过程中,综合运用了合成地震记录标定技术、方差体技术、蚂蚁体识别小断层技术、时深转换技术、三维可视化等技术,使断层解释和构造解释精度有了很大提高,为建立精确的地质模型和油田开发打下了良好基础。The 3D seismic data is of low S/N and resolution in GU oilfield,Sudan.The oilfield is located in a faulted basin and the structures are complex,which means that accurate structural interpretation is the prerequisite to ensure effective development.We integrated synthetic seismogram calibration,variance cube,ant cube,time-depth transition and 3D visualization technique to re-interpret the seismic data in this area.Fine structure interpretation has significantly improved the accuracy of fault and structure interpretation,which also laid a competent foundation for fine geologic modeling and oilfield development.
