| 摘 要： | 海拉尔盆地属于断陷盆地,断层发育,断块复杂,速度横向变化大;松辽盆地深层资料复杂,断层接触关系不清楚,火山岩特征不明显.为解决上述问题,利用克希霍夫叠前深度偏移技术对海拉尔盆地的巴彦塔拉、铜钵庙南工区和松辽盆地的丰乐工区的三维地震资料进行了处理,并与常规处理结果进行了对比分析.叠前深度偏移结果在构造信息和能量信息上均优于常规处理结果,经叠前深度偏移处理后的剖面,断层成像清晰,归位准确,地质形态更细致.

| Abstract: | Haila'er basin is a faulted-basin with complex faults and large variable lateral velocity. Songliao basin is a primary gas exploration area in the Daqing oilfield. Deep layers are mainly characterized by inconspicuous faulted contact and lava characteristics at the Songliao basin. Kirch-hoff prestack depth migration technology has been used in Bayan tala zone, southern Tongbo temple zone and Fengle zone. The result has been compared to the result of conventional prestack time migration technology. Prestack depth migration technology is better than conventional poststack time migration technology in structure and energy information. The sections of prestack depth migration have clearly imaging, exact location and fine geological configuration. |
