摘　　要：潜江凹陷蚌湖向斜在潜三段-四段沉积时发育滩坝岩性油藏,层与层之间成藏差异大,富集因素不清。以Eq4^(0)油组为例,通过对有效烃源岩识别及评价,分析出烃源岩厚度和有机碳含量与含油饱和度具有正相关的关系,得出小层烃源岩控富,对于同类型油藏高效勘探具有重要的指导意义。Beach bar lithologic reservoir was developed in the Banghu syncline during the deposition of the Eq3 and Eq4 members of Qianjiang sag.The reservoir-forming difference between layers is larger,and the enrichment factors are unclear.Taking Eq40 oil formation as an example,through the identification and evaluation of effective source rocks,the positive correlation between the thickness of source rocks,the content of organic carbon and the oil saturation is analyzed,and it is concluded that the sublayer source rocks control the enrichment.This insight has important directive significance for the efficient exploration of this type of reservoirs.
