摘　　要：针对松辽盆地腰英台地区圈闭幅度小、储层薄的特点,以高分辨率三维地震资料为基础,利用地震属性分析技术、地震相分析技术以及井间约束反演技术等,对研究区进行了综合分析,确定了砂体的沉积相与沉积环境,落实了有利岩性构造圈闭。本区泉四段以河流相为主,分流河道及边滩为砂体分布区;青一段、青二段为三角洲前缘亚相,主要以水下分流河道砂体、河口坝砂体、席状砂体为主。在此基础上,落实了2号、3号、4号和5 号圈闭,布署的2口井均获得了高产油气流。The trap amplitude is small and reservoir is thin in the Yaoyingtai Area, southern Songliao basin. According to this condition and from 3-D high resolution seismic data, seismic attribute extraction, seismic phase analysis and well-constrained inversion technique are applied comprehensively, the sediment environment and sediment state of sand were deduced after the comprehensive analysis, the favorable lithological-structural traps are determined. Implementation of these technologies shows good results.
