摘　　要：近三年来,大庆油田加大了高分辨率三维地震勘探技术的攻关力度,逐步形成了适合于松辽盆地北部中浅层薄互层岩性勘探、松辽盆地北部深层天然气勘探和海拉尔断陷盆地复杂断块勘探的高分辨率三维地震采集、处理和解释技术系列,地震资料品质不断提高。松辽盆地北部地震资料T1反射视主频70?80Hz,T2反射视主频60?70Hz,T5反射视主频40Hz左右;海拉尔盆地地震资料T2反射视主频55?60Hz,T5层反射视主频45Hz左右。在2001年到2003年期间,大庆油田共实施高分辨率三维地震4730.7km2,在松辽盆地北部岩性油藏的储量增长、深层火山岩天然气大型气藏发现和海拉尔盆地兴安岭群高产断块油藏、布达特群潜山油藏和铜钵庙岩性油藏勘探突破中发挥了关键作用。Daqing Oil Field has strengthened the efforts for study of high-resolution 3D seismic exploration technology in the recent three years and gradually developed its high- resolution 3D seismic data acquisition, processing and interpretation technological families, which are suitable for lithological exploration of shallow and middle-depth layers and thin layers in the northern part of Songliao Basin, deep-layer natural gas exploration in the area and exploration of complicated faulted blocks in Hailaer Fault Depression. The quality of seismic data has been raised continually. In the northern part of Songliao Basin, the re?ection video frequency is 70 ~ 80Hz for the seismic data T1, the re?ection video frequency 60 ~ 70Hz for the seismic data T2, and the re?ection video frequency is about 40Hz for the seismic data T5. In Hailaer Basin, the re?ection video frequency is 55~60Hz for the seismic data T2 and the re?ection video frequency about 45Hz for the seismic data T5. Daqing Oil Field conducted high-resolution 3D seismic survey for 4730.7 km2 between 2001 and 2003. Those technology have played a key role in boosting the reserves of lithologic oil reservoirs in the northern part of Songliao Basin, discovering the large-scale natural gas reservoir of deep-layer volcanic rock in the basin and high-yield faulted block oil reservoirs in Xing anling in Hailaer Basin, and making breakthroughs in exploration of Budatecun buried hill oil reservoir and Tongbomiao lithologic oil reservoir.
