摘要： 松辽 盆地西、南部沉积体系中部含油组合(青山口组、姚家组)河口坝、沿岸坝较为发育,其单层厚度大、横向迁移分布面积广,由河口坝、沿岸坝形成的厚层底水油气藏是该高砂地比发育区的一种重要的岩性油气藏。从河口坝、沿.岸坝的成因、分布以及内部结构研究入手,探讨了河口坝、沿岸坝与小断距断层和低幅度构造的成因关系,在分析了河口坝、沿岸坝含油气特征的基础上,探讨了其成藏机理、成藏主控因素以及分布规律,指出了勘探的有利目标区。

Abstract: The deposits of mouth bar and lakeshore bar are found at the middle oil-bearing assemblage (Qingshankou and Yaojia formations) in southern and western depositional systems, Songliao basin, characterized by large thickness and wide extension. The thick reservoirs with bottom water shaped by these bars are kinds of significant lithologic reservoirs in this area with high ratio of sand/total strata thickness. Based on the 0-rigin, distribution and internal structure of the bars, the genetic relationship between the bars and faults of minor slip and structures of low am-plitude is discussed. The petroliferous features of the bars are analyzed,by which the petroleum accumulation mechanism,mainly controlled factors and distribution are revealed, and the favorable target areas for petroleum exploration are pointed out in this paper.

Key words: Songliao basin, mouth bar, lakeshore bar, thick strata, bottom water reservoir, petroleum accumulation
