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 faci-es-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 sub-lacustrine fans of 447 km2 in area are oriented south-north 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.%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.
