通过对二连盆地已发现地层岩性油藏富集因素的分析, 认为在具备基本成藏条件的情况下, 形成规模富集岩性油藏主要受丰富的油源、优质的砂岩体圈闭、存在主汇流通道等3 个主要因素的控制。丰富的油气资源是形成富集的物质基础; 分布面积广、厚度大的优质砂体圈闭是形成富集的关键; 主汇流通道是形成富集油藏的最佳途径。

Based on the analysis of the enrichment factors for stratigraphic-lithologic reservoirs found in Erlian Basin, the enrichment of the stratigraphic-lithologic reservoirs is considered to be controlled by three main factors, including abundant oil sources, high quality sand body traps and main confluent passageway. Abundant oil sources are the background for the enrichment; high quality sand body traps which spread broadly are the key point for the enrichment; and the main confluent passageway is the best way for enrichment of the stratigraphiclithologic reservoirs.
