摘要: 东濮盆地是我国东部目前重点油气勘探地区之一,现已证实在下第三系各类砂岩体中聚集丰富的油气。查明盆地内砂体类型、特征、成因及分布规律,对今后油气勘探及开发有着十分重要的意义。Abstract: Dongpu Basin is a faulted basin formed by the disintegration of North China platform due to the intense block movement in Late Mesozoic. Continental sandstone and mudstone interbedded with halite and gypsum rock, 7000m thick, were deposited in Early Tertiary. The centre of the salt lake is in the northern part of the basin, where sandbodies are well developed.According to the sandbody geometry, sedimentary sequence, grain size, rocks and minerals, as well as electric loggin g, four main types of sandbodies can be distinguished.
