| 摘 要： | 本文利用叠前精细预处理、三维剩余速度分析，蒙特卡洛法自动速度拾取和三维克希霍夫叠前深度偏移等技术对海拉尔地区的三维地震资料进行了叠前深度偏移处理。与常规叠后时间偏移结果相比。浅、中层断层成像清楚。断面波发育，基底成像效果明显改进。深部反射结构清楚。地层接触关系清晰。为在该地区进一步进行油气勘探奠定了坚实基础。

| Abstract: | The paper used prestack fine pre-processing,3-D residual velocity analysis,Monte Carlo automatic velocity pick and 3-D Kirchhoff depth migration to carry out prestack depth migration processing of 3-D seismic data in Haila'er area.In comparison with ordinary poststack time migration,the results are characteristics of clear imaging of faults in shallow and medium beds,development of fault plane reflection,considerable improvement of basement imaging,distinct deep reflection structure and clear contact relation between the layers,which laid a solid foundation for further oil/gas exploration in the region. |
