摘　　要：综合利用钻井资料和三维地震资料,通过精细井震标定、地震正演、地震属性分析、古地貌分析和相控储层预测技术,在松辽盆地英台～他拉哈地区青一段、青二段发现深水湖底扇群。湖底扇分布受控于西部坡折带,呈南北向展布,在空间上呈透镜状分布,扇体总面积约447 km2。深水湖底扇烃源岩条件优越,储盖关系良好,具有较大油气勘探潜力,是松辽盆地不可忽视的勘探区域。With the comprehensive application of drilling data and 3-D seismic data,including wire-line-log calibration,seismic forward simulation,seismic at-tribute analysis,paleo-geomorphic analysis and facies-controlled reservoir prediction technology,a series of deepwater sub-lacustrine fan have been discovered in Qingl and Qing2 Group,Yingtai-Talaha area.Largely controlled by the western slope belt,the sublacustrine fans of 447 km2 in area are oriented southnorth displays lenticular shape in space distribution.Due to the favorable condition of hydrocarbon source rocks and well relationship of reservoir-cap rock,the deepwater sub-lacustrine fans have a huge petroleum exploration potential and can never be ignored in Songliao basin.
