英文摘要	松辽盆地属于大型陆相中生界含油气盆地,通过高分辨率三维地震资料分析,发现在松辽盆地北部嫩江组一段发育大规模重力流水道系统,嫩江组二三段发育多套滑塌体.研究认为嫩江组一段发育的大型重力流水道系统是由于河流直接入湖而形成;嫩江组二三段发育的3套滑塌体是由于三角洲前缘古地形坡度大、沉积物发生重力滑动所导致.研究松辽盆地大型陆相坳陷湖盆发育的沉积物重力流分布特征及其形成机制对在湖相泥岩中寻找岩性油气藏具有一定的指导意义.; Songliao Basin is a large-scale Mesozoic continental petroliferous basin. Based on analysis of high-resolution 3D seismic data, a large-scale sediment gravity flow channel system is identified in the Member 1 of Nenjiang Formation, and multiple sets of slip blocks are identified in the Member 2-3 of Nenjiang Formation in the north Songliao Basin. It indicates that this channel system resulted from the rushing of river into lake, and the 3 slip blocks resulted from gravity slumping of delta front sediment due to its great slope gradient, which will be transported by the earthquake or flood. It has extremely important meaning to hydrocarbon reservoirs within lacustrine mudstones of large-scale depression-lacustrine basin that we have made clear about the generation mechanism of sediment gravity flow in the Nenjiang Formation in the Songliao Basin.; "国家重点基础研究发展规划"项目; EI; 中文核心期刊要目总览(PKU); 中国科技核心期刊(ISTIC); 中国科学引文数据库(CSCD); 0; 3; 555-565; 24
