大庆探区三维地震勘探成效

在指出三维地震既是松辽盆地北部中浅层、深层和海拉尔盆地勘探成效的基础，也是解决中浅层岩性油藏、深层特殊岩性复合天然气气藏和海拉尔盆地复杂断块复式油气藏勘探的有效手段的基础上，阐明三维地震在松辽盆地北部深层勘探获得了重大突破、使海拉尔盆地获得了新生、是其他外围盆地获得发现的希望等观点。建议继续加大三维地震勘探工程量，为隐蔽油气藏精细勘探提供技术保障。

Achievements of 3D Seismic Exploration in Daqing Exploration Area

Through analysis on 3D seismic exploration in Daqing exploration area,this paper indicates that 3D seismic is not only the basis of exploration achievements of shallow-middle part and deep part of Songliao Basin and Hailaer Basin,but also an effective method for exploration in shallow-middle lithologic reservoirs,deep special lithologic compound gas reservoirs in Songliao Basin and complex fault block reservoirs.It illustrates that 3D seismic exploration makes great achievement in shallow-middle part,deep part of northern Songliao Basin and Hailaer Basin,showing potential of new discovery of other peripheral basins.It suggests to increase 3D seismic work in order to provide technical support for detailed exploration of subtle reservoirs.
