摘要
油气生成和聚集的基本单元是盆地。由于盆地内部在纵向上和平面上存在着明显的成藏条件、油气富集程度和油气藏特征方面的差异性,在盆地之下还要划分出次一级的评价单元。根据对世界上各种盆地的分析,盆地内纵向上地层层系之间的成藏条件和勘探工程条件的差异性大于盆内各个构造带之间的差异性。以层系为基础形成的成藏组合作为商业性的勘探单元适用于各类盆地,特别是对长期发育的多旋回盆地更具有重要意义。
Basin is the essential unit for hydrocarbon generation and migration.But among the hydrocarbon accumulation conditions,the abundance of hydrocarbon and the reservoir characters,there are many differences longitudinally and horizontally within a basin,so the sub unit of explorating evaluation needs be divided.After analyzing all kinds of basins in the world,it is found that in the hydrocarbon accumulation and the explorating-engineering conditions in the same basin there are many bigger differences in different longitudinal formations than in different structural belts.Accumulation association which is based on the longitudinal formations,they can fit all kinds of basins well when used as the basic exploration unit,and is particularly valueable for the long-time developped multicycle basins.
