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。
Over the past three years, Daqing Oilfield has stepped up its research efforts in high-resolution 3D seismic exploration technology and has gradually developed the lithologic exploration of thin and medium layers in the middle and shallow layers of the Songliao Basin, the deep natural gas exploration in the northern Songliao Basin and the Hailar fault High-resolution 3D seismic acquisition, processing and interpretation technology series of complex fault block exploration in the basin, and continuous improvement of seismic data quality. The T2 seismic reflection frequency is 70-80Hz, the T2 reflection frequency is 60-70Hz and the frequency of T5 reflection is about 40Hz. The seismic reflection T2 frequency of the Hailaer basin is 55-60Hz, About 45Hz frequency. During 2001-2003, Daqing Oilfield implemented a total of 4730.7km2 of high-resolution 3-D earthquakes, increasing reserves of lithologic reservoirs in the northern Songliao Basin. Large-scale gas reservoirs in deep volcanic rocks were found to be high-yielding fault block oil in the Xing’anling Group of the Hailar Basin Tibet, Budat Hill buried hill reservoirs and Tongbomiao lithologic reservoir exploration breakthrough has played a key role.
